Humans evolved to share beds – how your sleeping companions may affect you now

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/goffredina-spano-2240566">Goffredina Spanò</a>, <a href="https://theconversation.com/institutions/kingston-university-949">Kingston University</a> and <a href="https://theconversation.com/profiles/gina-mason-2240569">Gina Mason</a>, <a href="https://theconversation.com/institutions/brown-university-1276">Brown University</a></em></p> <p><a href="https://www.cell.com/trends/ecology-evolution/fulltext/S0169-5347(24)00176-9">Recent research</a> on animal sleep behaviour has revealed that sleep is influenced by the animals around them. Olive baboons, for instance, sleep less as group sizes increase, while mice can synchronise their rapid eye movement (REM) cycles.</p> <p>In western society, many people expect to sleep alone, if not with a romantic partner. But as with other group-living animals, human co-sleeping is common, despite some <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945710000377">cultural</a> and <a href="https://www.sciencedirect.com/science/article/abs/pii/S2352721820303053?via%3Dihub">age-related variation</a>. And in many cultures, bedsharing with a relative is considered typical.</p> <p>Apart from <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945710000377">western countries</a>, caregiver-infant co-sleeping is common, with rates as high as <a href="https://www.sciencedirect.com/science/article/abs/pii/S1087079216000265">60-100%</a> in parts of South America, Asia and Africa.</p> <p>Despite its prevalence, infant co-sleeping is controversial. Some western perspectives, that value self-reliance, argue that sleeping alone promotes self-soothing when the baby wakes in the night. But <a href="https://www.tandfonline.com/doi/abs/10.1080/00221325.2021.1905599">evolutionary scientists argue</a> that co-sleeping has been important to help keep infants warm and safe throughout human existence.</p> <p><a href="https://www.sleephealthjournal.org/article/S2352-7218(22)00077-8/abstract">Many cultures</a> do not expect babies to self-soothe when they wake in the night and see night wakings as a normal part of breastfeeding <a href="https://www.sciencedirect.com/science/article/pii/S1389945713002220?via%3Dihub">and development</a>.</p> <p>Concerns about Sudden Infant Death Syndrome (Sids) have often led paediatricians to discourage bed-sharing. However, when studies control for <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0107799">other Sids risk factors</a> including unsafe sleeping surfaces, Sids risk does not seem to differ statistically between co-sleeping and solitary sleeping infants.</p> <p>This may be one reason why agencies such as the <a href="https://publications.aap.org/pediatrics/article/150/1/e2022057990/188304/Sleep-Related-Infant-Deaths-Updated-2022?autologincheck=redirected">American Academy of Pediatrics</a>, the <a href="https://www.nice.org.uk/guidance/qs37/chapter/Quality-statement-5-Safer-practices-for-bed-sharing">National Institute for Health and Care Excellence</a> and the <a href="https://www.nhs.uk/conditions/baby/caring-for-a-newborn/reduce-the-risk-of-sudden-infant-death-syndrome/">NHS</a> either <a href="https://publications.aap.org/pediatrics/article/150/1/e2022057990/188304/Sleep-Related-Infant-Deaths-Updated-2022">recommend that</a> infants “sleep in the parents’ room, close to the parents’ bed, but on a separate surface,” or, if bedsharing, to make sure that the infant <a href="https://www.nice.org.uk/guidance/qs37/chapter/Quality-statement-5-Safer-practices-for-bed-sharing">“sleeps on a firm, flat mattress”</a> without pillows and duvets, rather than discouraging co-sleeping altogether.</p> <p>Researchers don’t yet know whether co-sleeping causes differences in sleep or, whether co-sleeping happens because of these differences. However, experiments in the 1990s suggested that co-sleeping can <a href="https://onlinelibrary.wiley.com/doi/10.1002/ajpa.20736">encourage more sustained and frequent bouts of breastfeeding</a>. Using sensors to measure brain activity, this research also suggested that infants’ and caregivers’ sleep may be lighter during co-sleeping. But researchers speculated that this lighter sleep may actually <a href="https://www.tandfonline.com/doi/full/10.1080/00221325.2021.1905599">help protect against Sids</a> by providing infants more opportunities to rouse from sleep and develop better control over their respiratory system.</p> <p>Other advocates believe that co-sleeping <a href="https://www.sciencedirect.com/science/article/abs/pii/S0163638319301237">benefits infants’ emotional and mental health</a> by promoting parent-child bonding and aiding infants’ <a href="https://www.tandfonline.com/doi/full/10.3109/10253890.2012.742057">stress hormone regulation</a>. However, current data is inconclusive, with most studies showing <a href="https://www.sciencedirect.com/science/article/abs/pii/S0163638319301249?via%3Dihub">mixed findings</a> or <a href="https://www.tandfonline.com/doi/full/10.1080/14616734.2024.2380427">no differences</a> between co-sleepers and solitary sleepers with respect to short and long-term mental health.</p> <h2>Co-sleeping in childhood</h2> <p>Childhood co-sleeping past infancy is also fairly common according to <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945713011076?via%3Dihub">worldwide surveys</a>. A <a href="https://publications.aap.org/pediatrics/article-abstract/126/5/e1119/65347/Relationship-Between-Bed-Sharing-and-Breastfeeding">2010 survey</a> of over 7,000 UK families found 6% of children were constant bedsharers up to at least four years old.</p> <p>Some families adopt co-sleeping <a href="https://capmh.biomedcentral.com/articles/10.1186/s13034-023-00607-w">in response to</a> their child having trouble sleeping. But child-parent bedsharing in many countries, including some western countries <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1471-6712.2005.00358.x">like Sweden</a> where children often co-sleep with parents until school age, is viewed culturally as part of a nurturing environment.</p> <p>It is also common for siblings to share a room or even a bed. A <a href="https://www.tandfonline.com/doi/full/10.1080/00221325.2021.1916732">2021 US study</a> found that over 36% of young children aged three to five years bedshared in some form overnight, whether with caregivers, siblings, pets or some combination. Co-sleeping decreases but is still present among older children, with up to <a href="https://onlinelibrary.wiley.com/doi/10.1111/fare.12955">13.8% of co-sleeping parents</a> in Australia, the UK and other countries reporting that their child was between five and 12 years old when they engaged in co-sleeping.</p> <p>Two recent US studies using wrist-worn actigraphs (motion sensors) to track sleep indicated that kids who bedshare may have <a href="https://jcsm.aasm.org/doi/10.5664/jcsm.11352">shorter sleep durations</a> than children who sleep alone. But this shorter sleep duration <a href="https://www.tandfonline.com/doi/full/10.1080/00221325.2021.1916732">is not explained by</a> greater disruption during sleep. Instead, bedsharing children may lose sleep by <a href="https://www.tandfonline.com/doi/full/10.1080/00221325.2021.1916732">going to bed later than</a> solitary sleepers.</p> <p>The benefits and downsides of co-sleeping may also differ in children with conditions such as <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945717303842">autism spectrum disorder</a>, <a href="https://link.springer.com/article/10.1007/s10802-017-0387-1">mental health disorders</a> and <a href="https://onlinelibrary.wiley.com/doi/10.1111/dmcn.13300">chronic illnesses</a>. These children may experience heightened anxiety, sensory sensitivities and physical discomfort that make falling and staying asleep difficult. For them, co-sleeping can provide <a href="https://link.springer.com/article/10.1007/s11325-018-1710-y">reassurance</a>.</p> <h2>Adults sharing beds</h2> <p>According to <a href="https://www.sleepfoundation.org/wp-content/uploads/2018/10/NSF_Bedroom_Poll_Report_1.pdf">a 2018 survey</a> from the US National Sleep Foundation, 80-89% of adults who live with their significant other share a bed with them. Adult bedsharing has shifted over time from pre-industrial <a href="https://academic.oup.com/ahr/article-abstract/106/2/343/64370?redirectedFrom=fulltext">communal arrangements</a>, including whole families and other household guests, to <a href="https://academic.oup.com/jdh/article-abstract/23/3/275/359439?redirectedFrom=fulltext">solo sleeping</a> in response to hygiene concerns as germ theory became accepted.</p> <p>Many couples find that bedsharing boosts their <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC1978364/">sense of closeness</a>. Research shows that bedsharing with your partner can lead to <a href="https://onlinelibrary.wiley.com/doi/10.1155/2017/8140672">longer sleep times</a> and a <a href="https://academic.oup.com/sleep/article-abstract/17/4/308/2753131">feeling of better sleep</a> overall.</p> <p>Bedsharing couples also often <a href="https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2020.00583/full">get into sync</a> with each other’s sleep stages, which can enhance that feeling of intimacy. However, it’s not all rosy. Some studies indicate that females in heterosexual relationships may struggle more with sleep quality when bedsharing, as they can be <a href="https://link.springer.com/article/10.1111/j.1479-8425.2007.00320.x">more easily disturbed</a> by their male partner’s movements. Also, bedsharers can have less <a href="https://pubmed.ncbi.nlm.nih.gov/27624285/">deep sleep</a> than when sleeping alone, even though they feel like their sleep is better together.</p> <p>Many questions about co-sleeping remain unanswered. For instance, we don’t fully understand the developmental effects of co-sleeping on children, or the benefits of co-sleeping for adults beyond female-male romantic partners. But, some work suggests that co-sleeping can <a href="https://link.springer.com/article/10.1007/s11325-018-1710-y">comfort us</a>, similar to other <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jsr.14174">forms of social contact</a>, and help to enhance <a href="https://onlinelibrary.wiley.com/doi/10.1002/ajpa.20736">physical synchrony</a> between parents and children.</p> <p>Co-sleeping doesn’t have a one-size-fits-all answer. But remember that western norms aren’t necessarily the ones we have evolved with. So consider factors such as <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945716301265">sleep disorders</a>, health and age in your decision to co-sleep, rather than what everyone else is doing.<!-- Below is The Conversation's page counter tag.

"A wonderful human being": Tributes flow for George Negus

<p>Tributes have poured in for George Negus, a founding presenter of Nine's <em>60 Minutes</em> and ABC's <em>Foreign Correspondent, </em>following his death at age 82. </p> <p>News of the broadcaster's death was announced by his family in an emotional statement saying that he had <a href="https://www.oversixty.com.au/health/caring/george-negus-dies-at-age-82" target="_blank" rel="noopener">died peacefully</a> surrounded by loved ones after a "gracious decline" from Alzheimer's disease. </p> <p>His family also said while Negus would be celebrated for his "unique contribution to journalism, football, and the environment" he would also want to be remembered for the  "incredible family man he was". </p> <p>"To us, 'Negsy' was the greatest father, grandfather, and partner there ever was," they said in the statement. </p> <p>"We created a beautiful life together and we will miss him dearly.</p> <p>"We would ask for privacy and time to farewell George in our own way with family, and his and our closest friends."</p> <p>Now, tributes have poured in from fellow colleagues, with TV personality Ray Martin saying that Negus was "more than a colleague, he was a mate".</p> <p>"He was probably the strongest TV character I can remember on Australian television," Martin said.</p> <p>"He was outrageous, he was charismatic, he was loud, he was heavily opinionated, he was funny but he was just a great bloke."</p> <p>Fellow journalist Liz Hayes has honoured him for being a "trailblazer" in Australian journalism, and praised his  "larger than life" personality. </p> <p>"George always had an insatiable appetite for information, but he was a regular guy too," Hayes said.</p> <p>"This is a guy who loved the cooking segment on the <em>Today</em> show, this is a guy who enjoyed sport and he was a family man."</p> <p>Prime Minister Anthony Albanese also paid tribute to Negus, remembering him as "a giant of Australian journalism".</p> <p>"His courage, curiosity and integrity gave millions of Australians a sense of the big issues on <em>60 Minutes</em>, and a window to the world through<em> Foreign Correspondent</em>," he said.</p> <p>"George sought and served the truth with steely determination and a twinkle in his eye, and along the way, he made even the smallest TV screen feel that much bigger.</p> <p>"He was a wonderful human being and his loss will be deeply felt by so many Australians.</p> <p>"We offer his family the heartfelt condolences of our nation. May he rest in peace."</p> <p>Negus is survived by his partner Kirsty, his two sons Ned and Serge as well as the rest of his family. </p> <p><em>Images: Nine News</em></p>

Making art is a uniquely human act, and one that provides a wellspring of health benefits

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/girija-kaimal-1486183">Girija Kaimal</a>, <a href="https://theconversation.com/institutions/drexel-university-1074">Drexel University</a></em></p> <p>When you think about the word “art,” what comes to mind? A child’s artwork pinned to the fridge? A favorite artist whose work always inspires? Abstract art that is hard to understand?</p> <p>Each of these assumes that making art is something that other people do, such as children or “those with talent.”</p> <p>However, as I explain in my book “<a href="https://global.oup.com/academic/product/the-expressive-instinct-9780197646229?q=the%20expressive%20instinct&amp;lang=en&amp;cc=ca">The Expressive Instinct</a>,” art is intrinsic to human evolution and history. Just as sports or workouts exercise the body, creating art exercises the imagination and is essential to mental as well as physical well-being.</p> <p>I am a <a href="https://scholar.google.com/citations?user=C8R2XOYAAAAJ&amp;hl=en">professor of art therapy</a> who studies how creative self-expression affects physical and emotional health. In our clinical research studies, my colleagues and I are finding that any form of creative self-expression – including drawing, painting, fiber arts, woodworking or photography – can <a href="https://doi.org/10.1080/08322473.2017.1375827">reduce stress</a>, improve mood and increase self-confidence.</p> <p>As a sickly child who needed to stay home from school a lot, I found that making art helped me cope. Today, creating art is my sanctuary. I use it as a sounding board to better understand myself and a way to recharge and learn from the challenges of life.</p> <h2>The uniquely human attribute of creativity</h2> <p>Although everyone has their own concept of what defines art, one thing is universally true: Creativity is a defining feature of the human species.</p> <p>How so? Well, human brains are not computers processing data. They are biological prediction machines that perceive the environment through memories and the senses, with the capacity to <a href="https://doi.org/10.3389/fnhum.2010.00025">use that information to imagine</a> plausible future scenarios.</p> <p>These inherent predictive and imaginative capacities are the wellspring of humanity’s abilities to survive and thrive – because self-expression is a safety valve that helps us cope with uncertainty. No one truly knows the future; they must live each day not sure of what will happen tomorrow. Art can help us all practice this imaginative muscle in a useful way.</p> <p>In our study examining brain activity while using virtual reality tools to create 3-D digital artwork, my team demonstrated that <a href="https://doi.org/10.1080/07421656.2021.1957341">creative expression is a natural state of being</a>. The brain naturally uses fewer cognitive resources to be expressive and creative, compared with the <a href="https://doi.org/10.1080/07421656.2021.1957341">brain power needed to do a rote task</a> that requires conscious effort.</p> <p>Seemingly ordinary everyday activities can provide opportunities to tap into one’s natural creativity and imagination: whipping up a meal from leftovers, figuring out an alternate route to work, dancing a little jig in response to hearing a song, or planting and tending a garden.</p> <p>We have repeatedly found in our studies that even a single session of real and honest self-expression can improve self-confidence and <a href="https://doi.org/10.1177/1534735420912835">reduce feelings of stress</a>, <a href="https://doi.org/10.1016/j.ejon.2019.08.006">anxiety and burnout</a>.</p> <p>This is partly because <a href="https://doi.org/10.1016/j.aip.2017.05.004">creativity activates reward pathways</a> in the brain. Using our hands and bodies to express ourselves activates dopamine pathways and helps us feel good. Dopamine is a neural messenger that is associated with feeling a <a href="https://doi.org/10.1016%2Fj.ajpath.2015.09.023">sense of hope, accomplishment or reward</a>. Our brains are wired to secrete <a href="https://theconversation.com/why-does-experiencing-flow-feel-so-good-a-communication-scientist-explains-173505">feel-good hormones whenever we move</a>, create something or engage in any type of expressive activity.</p> <p>Tapping into the creative resources within is <a href="https://theconversation.com/drawing-making-music-and-writing-poetry-can-support-healing-and-bring-more-humanity-to-health-care-in-us-hospitals-204684">one of the most underrated seeds of well-being</a> in the world.</p> <p>By comparison, bottling up or <a href="https://www.scientificamerican.com/article/why-the-secrets-you-keep-are-hurting-you/">denying these feelings can cause distress</a>, anxiety and fear because we have not processed and expressed them. This is probably one of the reasons why every community around the world has its own creative and expressive practices. Even our ancestors in Indigenous communities all around the world intuitively knew that <a href="https://doi.org/10.1016/j.aip.2021.101879">self-expression was essential</a> to emotional health and social connection.</p> <p>Being unable to share our lives, <a href="https://www.scientificamerican.com/article/why-the-secrets-you-keep-are-hurting-you/">keeping secrets</a> and feeling isolated and lonely tend <a href="https://doi.org/10.1016/j.neubiorev.2020.02.002">to worsen our health</a>. To our brains, social isolation feels like a chronic disease because it interprets this loneliness and inability to express as a threat to survival.</p> <p>Since creative expression can engage the senses, it can also be a body workout: a sensual as well as emotional and cognitive experience. Being active in expression – be it art, music, dance, drama, writing, culinary arts or working with nature – imparts a sense of confidence and hope that <a href="https://global.oup.com/academic/product/the-expressive-instinct-9780197646229?q=the%20expressive%20instinct&amp;lang=en&amp;cc=ca">challenges can be navigated and overcome</a>.</p> <h2>The role of art therapy</h2> <p>Given the integral role of art in our lives, it makes sense that making art can help people manage transitions, adversity and trauma, such as the stresses of puberty, the death of a loved one or <a href="https://doi.org/10.1016/j.ejon.2019.08.006">experiencing a serious illness</a>.</p> <p>According to a global study, 1 in 2 people will experience a <a href="https://doi.org/10.1016/S2215-0366(23)00193-1">mental-health-related challenge in their lifetime</a>, whether from life’s challenges, genetic predispositions or a combination of the two.</p> <p>This is where art therapy can come in. Art therapy is <a href="https://arttherapy.org/about-art-therapy/">a regulated mental health profession</a> in which clinical psychotherapists with extensive clinical training offer psychotherapy to patients with diagnosed mental health needs.</p> <p>The origins of art therapy go back to <a href="https://doi.org/10.1136/bmjopen-2017-021448">attempts to treat soldiers struggling with post-traumatic stress</a> during the 20th century’s two world wars. Today there is evidence that traumatic experiences tend to be stored as <a href="http://orcid.org/0000-0002-7316-0473">sounds, images and physical sensations</a> in the brain. When someone <a href="https://doi.org/10.1001/jama.2019.20825">lacks the words</a> to process these experiences through traditional talk therapy, art therapy can provide an indirect way to express and externalize those feelings and memories.</p> <figure><iframe src="https://www.youtube.com/embed/e-IiUcUVAwk?wmode=transparent&amp;start=3" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">The process of making art can help people process feelings that they aren’t able to put into words.</span></figcaption></figure> <p>One of art therapy’s unique strengths is that it provides nonverbal ways of communicating, processing and eventually managing the symptoms of post-traumatic stress disorder, or PTSD. In fact, in a recent study, my team has found that a personal history of trauma is related to <a href="https://doi.org/10.3389/fpsyg.2024.1337927">how people react to evocative images</a>. Images of distress and pain resonate with us when we have known similar kinds of distress ourselves. This implies that our life stories make us sensitized to distress in others and even personalize it more.</p> <p>Creative self-expression is especially relevant in coping with trauma because it provides an outlet through which a person <a href="https://doi.org/10.1177/1534735420912835">can regain a sense of agency</a> and control.</p> <h2>How to bring creativity into daily life</h2> <p>For those new to exploring art as a creative pursuit or for well-being reasons, engaging in creative activities begins with letting go of unrealistic expectations. Being creative isn’t about becoming a famous artist or even a mediocre one. It is about allowing ourselves to flex the creative muscle that we all have and enjoying all the sensory and emotional aspects of imagining.</p> <p>Next, think about activities that made you feel free to explore when you were a child. Did you like singing, playing in the outdoors, dancing, making up pretend plays, or writing little tales? Allow yourself to indulge in any and all of these creative pursuits that made you feel relaxed and joyful.</p> <p>A <a href="https://doi.org/10.1016/j.aip.2021.101879">cultural tradition</a>, tinkering with electronics, making a gift for someone or simply paying attention to everyday beauty – any of these can be a creative activity. And just like any muscle, the more you exercise it, the stronger it becomes. Over time, you will notice yourself getting more confident and adventurous in your creative practices.</p> <p>Whatever it is, make time for this creative pursuit every week – which is possibly the hardest step of them all. If it seems “unimportant” compared with the demands of daily life, such as work or family, try thinking of it as another form of sustenance.</p> <p>Remember that creativity is just as critical to human health as <a href="https://theconversation.com/helping-children-eat-healthier-foods-may-begin-with-getting-parents-to-do-the-same-research-suggests-225157">eating nutritious meals</a> or <a href="https://theconversation.com/yoga-modern-research-shows-a-variety-of-benefits-to-both-body-and-mind-from-the-ancient-practice-197662">getting exercise</a> and <a href="https://theconversation.com/whats-the-best-diet-for-healthy-sleep-a-nutritional-epidemiologist-explains-what-food-choices-will-help-you-get-more-restful-zs-219955">good rest</a>.

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/dr-neil-robinson-1312179">Dr Neil Robinson</a>, <a href="https://theconversation.com/institutions/university-of-salford-878">University of Salford</a></em></p> <p>Dark tourism has become a much more well-covered pasttime in recent years, in which a macabre fascination lead tourists to travel to various places not served by Thomas Cook: the sites of battles and genocides, war cemeteries, prisons, and even <a href="http://www.theatlantic.com/international/archive/2014/07/the-rise-of-dark-tourism/374432/">current warzones such as Syria</a>.</p> <p>The 20th century alone has provided such a <a href="http://www.therichest.com/expensive-lifestyle/location/10-great-places-to-visit-for-dark-tourism/">long list of places</a> at which catastrophes or great loss of life and suffering has occurred. Sites visited range from the spot from which JFK was assassinated, to prisons such as Alcatraz in San Francisco, through to battlefields of the World Wars, or the vestiges of genocides such at Auschwitz in Poland or Tuol Sleng in Phnom Penh, Cambodia. It’s not everybody’s cup of tea, but we shouldn’t condemn those for whom this is an interest.</p> <p>Dark tourism appears to be a manifestation of our media-rich society through which information found online may persuade us to see historical sites in person. But its origins can be traced back much further than the fascination with death and disasters of the 19th and 20th century. In the 11th century, people and pilgrims often visited places with religious significance such as Jerusalem, where the location of Christ’s crucifixion is a popular attraction; tourists visited Gettysburg, the site of the bloodiest battle of the American Civil War in 1863; and in more recent centuries, the Grand Tour offered an opportunity for the wealthy to experience Europe, with sites such as the classical ruins of the Colosseum in Rome – which in the name of entertainment saw execution, torture and death – one of the must-see attractions.</p> <p>Today, in parallel with the growth in popularity of dark tourism is the enormous growth of social media and the 24-hour news economy. The ease of access to such blanket coverage through the web, Facebook and Twitter has increased people’s awareness of, and fascination for, these historical sites of war, conflict and catastrophe. For example, the last decade has brought a surge in visitor numbers to <a href="https://theconversation.com/from-fiction-to-gallows-humour-how-chernobyl-survivors-are-still-coping-with-trauma-57923">Chernobyl</a>, where guides take visitors around the abandoned city of Pripyat (radiation levels permitting) which has been deserted since the nuclear power plant explosion on April 26, 1986. The 30th anniversary this year has in itself <a href="http://www.dailymail.co.uk/travel/travel_news/article-3526271/Chernobyl-tourists-pose-photos-eerie-sites.html">added to interest in visiting</a> the overgrown and crumbling city.</p> <p>As with tourism of any kind, this greater footfall brings benefits. In this case, not just the economic boost but also as a tool of education and even conflict resolution. For example, the <a href="http://www.belfasttours.com/package/belfast-political-mural-tour">taxi tours of Belfast’s murals</a>, which document Northern Ireland’s Troubles, offer visitors a way to understand the history and provide the communities involved a means to reflect and move on from the conflict. This model is <a href="http://www.h-net.org/reviews/showpdf.php?id=25852">viewed with interest</a> and hope by moderates on both sides of the Arab-Israeli divide searching for a peaceful solution for the long term.</p> <p>The tours of <a href="http://whc.unesco.org/en/list/916">Robin Island prison</a> in South Africa, where Nelson Mandela spent 18 years incarcerated among many others, starkly present how those imprisoned by a corrupt and discriminatory political regime can later engage in peace and reconciliation. The <a href="http://www.bruisedpassports.com/africa/5-reasons-you-must-go-for-a-township-tour-in-south-africa">Soweto township tours</a> in Johannesburg have acted in part as a means through which generations of South Africans can better understand their country’s dark past and help to establish truth and reconciliation for the future.</p> <p>Dark tourism should not in my opinion by viewed as unethical, repugnant or even a self-indulgent activity. Certainly some dark tourists may engage in their pursuits for all the wrong reasons, seeing death and destruction as a commodity to be consumed with little thought for those who caught up in its wake. But others visit such sites to pay their respects, to better understand the magnitude of death and destruction, and to inform the outside world of the details of terrible events – even in some case offering to help. These are positive effects that may come from so much pain and suffering.</p> <p>We should strive to better understand the origins of the terrible events of human history to be more able to prevent us repeating them. In this regard, that more people visit sites associated with dark tourism and learn about them should be seen as a positive.<!-- Below is The Conversation's page counter tag.

"Force of nature": Tributes flow for Shannen Doherty

<p>Shannen Doherty has passed away aged 53. </p> <p>The beloved actress, known for her roles on <em>Little House on the Prairie</em>, <em>Charmed</em> and <em>90210</em>, died over the weekend following a nine-year battle with breast cancer. </p> <p>Doherty's death was confirmed by her publicist, Leslie Sloane, who said in a statement: "It is with a heavy heart that I confirm the passing of actress Shannen Doherty. On Saturday, July 13, she lost her battle with cancer after many years of fighting the disease."</p> <p>"The devoted daughter, sister, aunt and friend was surrounded by her loved ones as well as her dog, Bowie. The family asks for their privacy at this time so they can grieve in peace."</p> <p>Tributes have flowed in for Doherty from friends, co-stars and loved ones, who have remembered her as a "force of nature". </p> <p>"Shannen Doherty had the heart of a lion," fellow<em> Charmed </em>co-star Rose McGowan wrote in a tribute shared to Instagram. </p> <p>"Passion for craft is often mislabelled as trouble. Shannen was passion," McGowan continued.</p> <p>"I met her in the 90s and was awed. Getting to really know her later in life, a beautiful gift. This woman fought to live," McGowan added, before praising Doherty's work ethic which was "inspiring to the end".</p> <p>"Shannen's great love for directing, for acting, Holly [Marie Combs], her friends, her parents, dog and her beloved fans was legendary."</p> <p>"Our lives had been intertwined in a unique way. We laughed at dark forces who wanted us to hate each other, instead we chose love and respect. A soft-hearted badass as there ever was. A force of energy that will live forever in hearts," McGowan wrote. </p> <p>"Rest now warrior, we will never forget you dear sister."</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/C9aLxGVvLH_/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/C9aLxGVvLH_/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Rose McGowan (@rosemcgowan)</a></p> </div> </blockquote> <p>Fellow Charmed co-star Alyssa Milano - who Doherty had a complicated relationship with - also paid tribute to her via a statement shared with<em> People</em>. </p> <p>"It's no secret that Shannen and I had a complicated relationship, but at its core was someone I deeply respected and was in awe of," Milano wrote.</p> <p>"She was a talented actress, beloved by many and the world is less without her.

Hope: A double-edged sword in the human experience

<p>Hope has long been cherished as a source of strength in times of adversity. Yet, as explored in this edited extract from his new book <em>The Human Condition</em> by author Tony Grey, this fundamental emotion is not without its complexities and potential pitfalls.</p> <p>---</p> <p>As in the host of challenges explored in <em>The Human Condition</em>, the feeling of expectation and desire for something beneficial to happen, which we call hope, is as fundamental to the human condition as the will to survive; they’re linked within the evolutionary imperative. As Cicero pointed out, “dum spiro spero” (while I breathe I hope). Hope is a rolling prayer to life as time moves on, a whisper to the soul that things will turn out all right. </p> <p>The sentiment is generally unchallenged. Why should it be? In times of trouble, we need the balm of hope. Samuel Johnson said, “Hope is a species of pleasure, and perhaps, the chief pleasure this world affords.”</p> <p>While usually positive about hope, Greek philosophers were sometimes ambivalent about it, citing its propensity, through wishful thinking, to encourage indolence or actually cause harm. In Sophocles’ play Antigone, the Chorus sings, “Hope whose wanderings are so wide is to many men a comfort, but to many a false lure of giddy desires.” Plato observes that hope breeds a confidence which can exacerbate a precondition of arrogance in the powerful, leading to serious wrongdoing. “It is among these men that we find the ones who do the greatest evils.” </p> <p>Napoleon and Hitler are examples. And so is the Japanese government responsible for the Pearl Harbour attack.  At the World War Two surrender on the deck of the USS Missouri, a Japanese general was heard to say when he looked at the sky blackened by Allied aircraft flying past and the sea bursting with warships, “How did we ever hope we could win?”</p> <p>On the other hand, Plato stressed the motivational properties of hope when directed towards a good aim. And Aristotle links hope with the virtue of megalopsychia (high-mindedness) resulting from its inspirational role.</p> <p>I have an experience of this in my family. My nephew was born to my sister with intellectual disability, and other difficulties. His condition seemed hopeless. Nevertheless, from the first, hope was my sister’s support; it gave her the energy to carry on. Through the gloom it afforded a glimpse into the future where progress beckoned. And all along she demonstrated that hope is ineluctably linked to love.</p> <p>Aided by her husband, the father, she worked day and night teaching and inspiring the boy. When old enough he went to a special needs school and gradually progressed, indefatigably supported at home. Over time his condition improved so that eventually he could take and keep a simple job, cook food, and have friends (similarly disabled), a state absolutely unforeseeable at his early stage of life. Throughout all the difficulties, frustrations and threats of despair, hope sustained my sister and guided her to the wonderful achievement of saving a human life.</p> <p>In most instances, hope is personal in the sense that something specific to the individual or those who are close is wanted. However, it can range far beyond that into areas involving others such as team sports, politics, economic activity, justice, national and tribal identity, international relations – notably war, and pandemics like Covid. Within these fields, hope calls out for the survival and well-being of humanity and its prospects for moral and material progress. Such hope embraces faith in something bigger than the individual. If human beings have a purpose, its linked to that, and its fulfillment is somehow bound up in hope.</p> <p>This approach cries out for exploring a whole array of other challenges inherent in the human condition.</p> <p><strong>ABOUT THE AUTHOR</strong></p> <p>Tony Grey is an accomplished author residing in Sydney. His latest book, <em>The Human Condition</em>, ambitiously explores the hurly burly of human existence, and is available now for purchase through Halstead Press Publishers. Tony is the founder of Pancontinental Mining, a former director of Opera Australia and the Conservatorium of Music, and a former trustee of the Art Gallery of New South Wales. Other books by Tony Grey include <em>Jabiluka</em>, <em>East Wind</em> and <em>Seven Gateways</em>.

"An insult to human dignity": Mother of Bondi stabbing victim hits out at the media

<p>The mother of Bondi stabbing victim Jade Young has hit out at how social media and major news outlets reported on her daughter's death. </p> <p>Jade Young, 47, was one of six people fatally stabbed by Joel Cauchi during his violent rampage at Bondi Junction Westfield on April 13th. </p> <p>Following the tragedy, graphic videos and images of the attacks were circulated online.</p> <p>Now, Jade's mother Elizabeth Young, writing in the <a href="https://www.smh.com.au/national/nsw/my-daughter-was-killed-in-the-bondi-junction-attack-how-my-family-found-out-is-shameful-20240429-p5fnbw.html" target="_blank" rel="noopener">Sydney Morning Herald</a> on Wednesday, said it was “shameful” how her family found out about Jade’s death.</p> <p>“Members of my family recognised Jade and her husband Noel in uncensored vision being played on a mainstream TV news feed, with vision of Jade lying on the ground at the shopping centre, receiving CPR,” she wrote.</p> <p>“The vision, shared on social media and picked up — and used by — multiple news media programs shared my daughter’s final moments with millions. Finding out that a loved one has been murdered is a horror that I do not wish on anyone. But seeing the vision of their last moments and knowing it has been broadcast to millions of people is an appalling breach of privacy and an insult to human dignity.”</p> <p>Ms Young went on to say how some of the major media organisations that shared violent images of the Bondi stabbing “approached our family within hours of the attack, offering their condolences … and the opportunity to share our family’s story”.</p> <p>“These same media organisations reported the failure of a certain popular social media platform to take down videos, without acknowledging their own complicity,” she said.</p> <p>“I am not surprised at their hypocrisy, but I am angry.”</p> <p>“Sharing violent images or personal material from the lives of victims of crime is not free speech — it is enormously profitable for some but it’s speech with a steep price for the victims,” she said.</p> <p>“Those who run social media platforms are remote from the pain inflicted by their uploads and the dystopia they have helped create. It is the victims who bear the cost.”</p> <p>Last week, hundreds of mourners attended a public memorial for Ms Young, an acclaimed architect and mother-of-two, where mourners were encouraged to wear colourful clothing “in memory of Jade”.</p> <p><em>Image credits: Getty Images / Facebook </em></p>

Elephant tourism often involves cruelty – here are steps toward more humane, animal-friendly excursions

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/michelle-szydlowski-1495781">Michelle Szydlowski</a>, <a href="https://theconversation.com/institutions/miami-university-1934">Miami University</a></em></p> <p>Suju Kali is a 50-year-old elephant in Nepal who has been carrying tourists for over 30 years. Like many elephants I encounter through my <a href="https://doi.org/10.1080/10888705.2022.2028628">research</a>, Suju Kali exhibits anxiety and can be aggressive toward strangers. She suffers from emotional trauma as a result of prolonged, commercial human contact.</p> <p>Like Suju Kali, many animals are trapped within the tourism industry. Some venues have no oversight and little concern for animal or tourist safety. Between 120,000 and 340,000 animals are used globally in a variety of wildlife tourism attractions, including <a href="https://doi.org/10.1371/journal.pone.0138939">endangered species</a> like elephants. Over a quarter of the world’s <a href="https://www.iucnredlist.org/species/7140/45818198">endangered elephants</a> reside in captivity with little oversight.</p> <p>Wildlife tourism – which involves viewing wildlife such as primates or birds in conservation areas, feeding or touching captive or “rehabilitated” wildlife in facilities, and bathing or riding animals like elephants – is <a href="https://doi.org/10.1080/14724049.2022.2156523">tricky business</a>. I know this because I am <a href="https://scholar.google.com/citations?user=YbweA2MAAAAJ&amp;hl=en">a researcher studying human relationships with elephants</a> in both tourism and conservation settings within Southeast Asia.</p> <p>These types of experiences have long been an <a href="https://kathmandupost.com/money/2021/06/17/tourism-is-nepal-s-fourth-largest-industry-by-employment-study">extremely popular and profitable</a> part of the <a href="https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1002074">tourism market</a>. But now, many travel-related organizations are urging people not to participate in, or <a href="https://www.usatoday.com/story/travel/destinations/2018/04/27/animal-welfare-travelers-how-enjoy-wildlife-without-harming/544938002/">calling for an outright ban on, interactive wildlife experiences</a>.</p> <p>Tourism vendors have started marketing more “ethical options” for consumers. Some are attempting to truly improve the health and welfare of wildlife, and some are transitioning captive wildlife into touch-free, non-riding or lower-stress environments. In other places, organizations are attempting to <a href="https://www.fao.org/documents/card/es/c/b2c5dad0-b9b9-5a3d-a720-20bf3b9f0dc2/">implement standards of care</a> or create manuals that outline good practices for animal husbandry.</p> <p>This marketing, academics argue, is often simply “<a href="https://doi.org/10.1016/j.gecco.2017.11.007">greenwashing</a>,” <a href="http://dx.doi.org/10.1080/13683500.2023.2280704">applying marketing labels to make consumers feel better</a> about their choices without making any real changes. Worse, research shows that some programs marketing themselves as ethical tourism may instead be widening economic gaps and harming both humans and other species that they are meant to protect.</p> <h2>No quick fix</h2> <p>For example, rather than tourist dollars trickling down to local struggling families as intended by local governments, many tourism venues are owned by nonresidents, <a href="http://dx.doi.org/10.3126/japfcsc.v2i1.26746">meaning the profits do not stay in the area</a>. Likewise, only a small number of residents can afford to own tourism venues, and venues do not provide employment for locals from lower income groups.</p> <p>This economic gap is especially obvious in Nepalese elephant stables: Venue owners continue to make money off elephants, while elephant caregivers continue to work 17 hours a day for about US$21 a month; tourists are led to believe they are “<a href="https://www.cabidigitallibrary.org/doi/book/10.1079/9781800624498.0000">promoting sustainability</a>.”</p> <p>Yet, there are no easy answers, especially for elephants working in tourism. Moving them to sanctuaries is difficult because with no governmental or global welfare oversight, elephants may end up in worse conditions.</p> <p>Many kindhearted souls who want to “help” elephants know little about their biology and mental health needs, or what it takes to keep them healthy. Also, feeding large animals like Suju Kali is pricey, <a href="https://doi.org/10.3390/ani14010171">costing around $19,000 yearly</a>. So without profits from riding or other income, owners – or would-be rescuers – can’t maintain elephants. Releasing captive elephants to the jungle is not a choice – many have never learned to live in the wild, so they cannot survive on their own.</p> <h2>Hurting local people</h2> <p>Part of the problem lies with governments, as many have marketed tourism as a way to fund conservation projects. For example in Nepal, a percentage of ticket sales from elephant rides are given to community groups to use for forest preservation and support for local families.</p> <p>Increasing demand for <a href="https://www.routledge.com/Tourism-and-Animal-Ethics/Fennell/p/book/9781032431826">wildlife-based tourism</a> may increase traffic in the area and thus put pressure on local governments to further limit local people’s access to forest resources.</p> <p>This may also lead to <a href="https://www.worldanimalprotection.org/latest/news/un-world-tourism-organisation-urged-create-better-future-animals/">increased demands on local communities</a>, as was the case in Nepal. In the 1970s, the Nepalese government removed local people from their lands in what is now Chitwan National Park as part of increasing “conservation efforts” and changed the protected area’s boundaries. Indigenous “Tharu,” or people of the forest, were forced to abandon their villages and land. While some were offered access to “buffer zones” in the 1990s, many remain poor and landless today.</p> <p>In addition, more and more desirable land surrounding conservation areas in Nepal is being developed for tourist-based businesses such as hotels, restaurants and shops, <a href="http://dx.doi.org/10.3126/japfcsc.v2i1.26746">pushing local poor people farther away</a> from central village areas and the associated tourism income.</p> <p>Some activists would like humans to simply release all wildlife back into the wild, but <a href="https://www.cabidigitallibrary.org/doi/book/10.1079/9781800624498.0000">there are multiple issues</a> with that. Elephant habitats throughout Southeast Asia have been transformed into croplands, cities or train tracks for human use. Other problems arise from the fact that tourism elephants have <a href="https://doi.org/10.4324/9781315457413">never learned</a> how to be elephants in their natural elements, as they were <a href="https://www.pugetsound.edu/sites/default/files/file/8342_Journal%20of%20Tourism%20%282009%29_0.pdf">separated from their herds</a> at an early age.</p> <p>So tourism may be vital to providing food, care and shelter to captive elephants for the rest of their lives and providing jobs for those who really need them. Because elephants can live beyond 60 years, this can be a large commitment.</p> <h2>How to be an ethical tourist</h2> <p>To protect elephants, tourists should check out reviews and photos from any venue they want to visit, and look for clues that animal welfare might be impacted, such as tourists allowed to feed, hold or ride captive wildlife animals. Look for healthy animals, which means doing research on what “healthy” animals of that species should look like.</p> <p>If a venue lists no-touch demonstrations – “unnatural” behaviors that don’t mimic what an elephant might do of their own accord, such as sitting on a ball or riding a bike, or other performances – remember that the behind-the-scenes training used to achieve these behaviors can be <a href="https://doi.org/10.21832/9781845415051-014">violent, traumatic or coercive</a>.</p> <p>Another way to help people and elephant is to to use small, local companies to book your adventures in your area of interest, rather than paying large, international tourism agencies. Look for locally owned hotels, and wait to book excursions until you arrive so you can use local service providers. Book homestay programs and attend cultural events led by community members; talk to tourists and locals you meet in the target town to get their opinions, and use local guides who provide wildlife viewing opportunities <a href="https://nepaldynamicecotours.com/">while maintaining distance from animals</a>.</p> <p>Or tourists can ask to visit <a href="https://www.americanhumane.org/press-release/global-humane-launches-humane-tourism-certification-program/">venues that are certified</a> by international humane animal organizations and that <a href="https://www.su4e.org/">do not allow contact</a> with wildlife. Or they can opt for guided hikes, canoe or kayak experiences, and other environmentally friendly options.</p> <p>While these suggestions will not guarantee that your excursion is animal-friendly, they will help decrease your impact on wildlife, support local families and encourage venues to stop using elephants as entertainment. Those are good first steps.<!-- Below is The Conversation's page counter tag.

How to fall asleep without sleeping pills: 7 natural sleep aids that actually work

<p>It’s 3am and you’re suddenly wide awake. Try these seven science-backed strategies to fall back to sleep fast.</p> <p><strong>Give meditation a try </strong></p> <p>As a mindfulness coach, I’m very aware of the day-to-day anxieties and worries that can interfere with a good night’s sleep. One of the most effective natural sleep aids is a quick meditation session to ease yourself out of those stresses. If you’ve never meditated before, you’ll likely find the meditation interrupted by thoughts flashing through your mind.</p> <p>It’s important for you to know that this isn’t a failure on your part, and that you aren’t doing anything wrong. Thinking is just what the brain does, as naturally as lungs take in air. The point is to be non-judgmental yet aware of your thoughts, bodily experiences and breath, moment by moment.</p> <p><em>Sleep better, feel better! <a href="https://gaiam.innovations.com.au/p/gaiam-wellness/rollers-resistance/27-72435-gaiam-strengthen-stretch-kit?affiliate=GAIAM6O" target="_blank" rel="noopener">This Blackout Sleep Mask from Gaiam</a> will help you feel well rested and renewed. </em></p> <p><strong>Stop wanting to fall asleep</strong></p> <p>It’s counterintuitive, isn’t it? Sometimes trying too hard to do something is the very thing that prevents us from achieving it – and that’s never more true than when it comes to falling asleep. Desperately wanting to sleep will only stoke anxieties that will further stress your brain, essentially feeding it the message that it’s not safe to sleep.</p> <p>Throw in those worries about your to-do list at work the following day, and the whole thing can snowball into a panic attack. Try letting go of that feeling that you absolutely must sleep now, and observe your own anxieties for what they are without judgment. When you stop looking at sleep as a goal, you’ll find it easier to fall asleep.</p> <p><em>Before you climb into bed, set aside 10-15 minutes to help relax your body and mind, with <a href="https://gaiam.innovations.com.au/p/gaiam-wellness/restore-massage/27-73353-gaiam-wellness-acupressure-neck-back-pillow?affiliate=GAIAM60" target="_blank" rel="noopener">this wellness acupressure neck and back pillow from Gaiam</a>.</em></p> <p><strong>Start a journal </strong></p> <p>If you find yourself struggling to fall asleep, pick up a pen and paper (not your phone!), and start writing: simply scribble down an account of what’s going on inside your head. Although there’s no “right” way to journal, you might start by listing the events of your day, and from there, how those events and encounters made you feel.</p> <p>Building this structured picture of your thoughts may help you see that the problem that’s keeping you up at night, and is likely less overwhelming than you thought. Why my insistence on a pen and paper? First off, studies show the simple motor action that’s involved in the act of handwriting has a calming effect. Secondly, the light emitted by laptops and phones isn’t conducive to falling asleep.</p> <p><strong>Find yourself a "3am friend"</strong></p> <p>Some of us are lucky to have a ‘3am friend’, that close confidant you can call up in the wee hours knowing that they won’t hold it against you in the morning. Although it’s great to have someone to talk to when you want to fall asleep, it’s important that the conversation doesn’t just rehash the anxieties that are preventing you from catching shut-eye in the first place.</p> <p>Rather than using the call to seek solutions for those issues, talk about things that calm your nerves, or even have them assist you in deep breathing. It may sound silly, but doing a series of deep, relaxing breaths can help you let go of the troubles that are keeping you wide awake.</p> <p><strong>Take a warm shower</strong></p> <p>Taking a warm shower not only relaxes your muscles and soothes minor aches and pains, but it also raises your core body temperature. As soon as you step out of the shower, your body starts working at lowering that temperature, which is something that normally happens when you’re falling asleep naturally.</p> <p>(That’s why we always feel the need for a blanket when we sleep, no matter how warm it is!) By kick-starting that temperature-lowering process, you’re tricking your body into falling asleep fast.</p> <p><strong>Stretch yourself to sleep </strong></p> <p>Anxiety keeping you up? Research suggests mild stretching can help take the edge off and relax muscles that have become stiff and sore after a long day. We’re not talking intricate yoga poses or acrobatics here, either: Simple stretches like an overhead arm stretch and bending over to touch your toes should do the trick. Ramp up the relaxation potential with a soundtrack of ambient noise at a volume that’s just barely audible.</p> <p>There are plenty of white noise apps that are free to download, but soft music can work as well (so long as there are no lyrics). Just remember, if you’re using an electronic device to play these sleep-promoting sounds, make sure it’s placed screen-down so you’re not distracted by the light it emits.</p> <p><em>Stretching is healing, and this <a href="https://gaiam.innovations.com.au/p/gaiam-wellness/rollers-resistance/27-72435-gaiam-strengthen-stretch-kit?affiliate=GAIAM60" target="_blank" rel="noopener">Strengthen and Stretch Kit from Gaiam</a> is a great way to start. An on-line workout is also included to get you started.</em></p> <p><strong>Read (or listen!) to something new</strong></p> <p>When you’re struggling with insomnia, it might be tempting to pull an old favourite off the bookshelf. In reality, it’s better to read or listen to an audio book that covers a topic on which you know absolutely nothing. New information, while taking attention away from the stressors that are keeping you up at night, gives your brain enough of a workout to make it tire more quickly than when it’s engaged with familiar subjects and concepts.</p> <p>Again, if it’s an audio book or podcast you’re listening to, make sure the light-emitting side of the device is face down to keep the room as dark as possible. Darkness and warmth play an essential part in the production and maintenance of melatonin, the hormone that plays the central role falling asleep.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article by </em><em>Deepak Kashyap </em><em style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/conditions/sleep/how-to-fall-asleep-without-sleeping-pills-7-natural-sleep-aids-that-actually-work" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Our dogs can terrify (and even kill) wildlife. Here’s how to be a responsible owner this summer

<p><em><a href="https://theconversation.com/profiles/melissa-starling-461103">Melissa Starling</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>In Australia, dog ownership often goes hand-in-hand with a love for the great outdoors. Whether it’s walking on the beach, going camping, or having a barbecue in the park, we tend to keep our canine companions close as we soak up the sun.</p> <p>But many of us forget a key fact about our dogs: they are predators. Even the fluffy little 5kg ball that spends most of its time in your lap derives from an apex predator – and its predatory instincts can kick in at any time.</p> <p>And while many of our dogs don’t have the same hunting skills as their distant ancestors (who had to hunt for a living), wildlife doesn’t know that.</p> <p>The impacts of domestic dogs on wildlife aren’t well studied, and likely vary depending on the environment. Nonetheless, there’s good evidence domestic dogs, when left unobserved, can have detrimental effects in the places they visit.</p> <p>With that in mind, here are some things to consider next time you take your pup out for a bushwalk.</p> <h2>How dogs impact ecosystems</h2> <p>There are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0006320717305967">five main ways</a> domestic dogs can negatively impact the natural environments they visit. These are:</p> <ol> <li>direct physical harm through predatory behaviour</li> <li>disturbance through chasing and harassment</li> <li>increased exposure to diseases</li> <li>interbreeding, which can alter the gene pool of wild canid populations</li> <li>increased competition for resources.</li> </ol> <p>The good news is the last three points aren’t particularly relevant in Australia. For one thing, there’s little overlap between diseases common in domestic dogs and Australian wildlife. There’s also little resource overlap, except perhaps in some areas where feral or semi-feral dogs live alongside dingoes.</p> <p>And regarding potential interbreeding, while it was once thought this could threaten the dingo gene pool, <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/mec.16998">recent research</a> suggests it’s not nearly as common as we thought.</p> <p>As such, the main harms Aussie dog owners should focus on are physical harms through predatory behaviour and disturbance to ecosystems.</p> <h2>Dogs can kill</h2> <p>We know dogs are capable of injuring and killing wildlife, but it’s difficult to determine how common this is, because many events go unreported. While smaller animals such as lizards, gliders and possums are at higher risk, larger species such as koalas can also fall prey to dogs.</p> <p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0206958">One study</a> that looked at wildlife coming into care at Queensland rehabilitation centres reported dog attacks as the cause in about 9% of cases. These cases often resulted in severe injury or death.</p> <p>Dog owners should be especially wary of small, localised populations of vulnerable species. A <a href="https://ri.conicet.gov.ar/bitstream/handle/11336/202640/CONICET_Digital_Nro.29048152-7a5c-4ea2-8068-e73d42cba01d_B.pdf?sequence=2&amp;isAllowed=y">study</a> in Argentina’s Patagonia region details several cases of dogs decimating local penguin populations after gaining access to protected island areas during low tide.</p> <p>Not to mention, dog attacks on wildlife can bring risk to dogs as well. Kangaroos can defend themselves with <a href="https://www.abc.net.au/news/2023-10-16/mildura-man-fights-kangaroo-to-protect-dog/102983926">their powerful limbs</a>, monitor lizards are equipped with sharp claws and teeth, and many snake species <a href="https://www.brisbanetimes.com.au/national/queensland/dogs-twice-as-likely-to-die-from-snake-bite-as-cats-research-finds-20200519-p54ufd.html">are highly venomous</a>.</p> <h2>The impact of harassment</h2> <p>You might think it’s harmless for your dog to chase wildlife if it never manages to catch the animals it chases, but that isn’t true. Wild animals optimise their behaviours to meet their needs for foraging, breeding and resting, and being chased by a dog can disrupt this.</p> <p>For example, certain threatened bird species will nest on the beach and find foraging opportunities based on the tides. One dog forcing one bird to abandon this important activity may have a small impact. But if it happens repeatedly throughout the day, it can become a <a href="https://wilderness-society.org/wp-content/uploads/2019/04/Dogs-as-agents-of-disturbance-Michael-A.-Weston-and-Theodore-Stankowich.pdf">much bigger problem</a>. It may even drive animals out of the area.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2391219/">Research</a> conducted in Sydney has shown the mere presence of a leashed dog is enough to temporarily, yet dramatically, reduce the number of bird species detected.</p> <h2>Keep an eye on your furry pal</h2> <p>Responsible dog ownership involves making sure our dogs have a minimal impact on others, including wildlife. How can we achieve this when our dogs are simply engaging in behaviours that come naturally to them, and may even be rewarding for them?</p> <p>Training your dog to have general obedience – especially to come when called – is worth sinking considerable time and effort into. This can save both your dog and any wildlife they may be after. For instance, calling a dog away from a snake is one of the most effective ways of managing snake bite risk.</p> <p>One <a href="https://www.researchgate.net/publication/333344634_Applying_Social_Marketing_to_Koala_Conservation_The_Leave_It_Pilot_Program">pilot study</a> in Victoria found positive outcomes from a program that helped owners train their dogs to be more obedient around wildlife.</p> <p>That said, recall training is an art form, and recalling a dog that likes to run off and chase animals can be a huge challenge.</p> <p>Another solution is to rely on leashes when passing sensitive areas, or where there’s a risk of wildlife harassment. In Australia, many beaches that allow dogs have signs with information about vulnerable birds in the area and how to protect them from your dog.</p> <p>This could mean keeping your dog off rock platforms, leashing them when you see birds foraging on the beach, or keeping them out of fenced areas. Some areas are simply too vulnerable for dogs to run amok, so always look for signs and read them carefully.</p> <p>If you’re hiking, use a long line (a leash that’s more than five metres long) and look for signs of your dog detecting something of interest. Often their ears will come up high and forward, and they will freeze and stare intently.</p> <p>At this point, it doesn’t matter what they’re excited about: take the opportunity to leash them or shorten their leash, and get their attention before they can take off. Investing in a long leash will allow your dog more freedom without putting wildlife at risk.</p> <p>If your dog does injure an animal, you should quickly contact a wildlife rescue organisation or take the animal to a veterinary practice or sanctuary. For small animals, even minor injuries from a dog will usually require veterinary attention.</p> <p>It’s our responsibility to be respectful visitors when we’re out in nature, and to make sure our dogs are too. <!-- Below is The Conversation's page counter tag.

Taste depends on nature and nurture. Here are 7 ways you can learn to enjoy foods you don’t like

<p><em><a href="https://theconversation.com/profiles/nicholas-archer-181464">Nicholas Archer</a>, <a href="https://theconversation.com/institutions/csiro-1035">CSIRO</a> and <a href="https://theconversation.com/profiles/astrid-poelman-1481227">Astrid Poelman</a>, <a href="https://theconversation.com/institutions/csiro-1035">CSIRO</a></em></p> <p>You’re out for dinner with a bunch of friends, one of whom orders pizza with anchovies and olives to share, but you hate olives and anchovies! Do you pipe up with your preferred choice – Hawaiian – or stay quiet?</p> <p>This scene plays out every day around the world. Some people ferociously defend their personal tastes. But many would rather expand their palate, and not have to rock the boat the next time someone in their friend group orders pizza.</p> <p>Is it possible to train your tastebuds to enjoy foods you previously didn’t, like training a muscle at the gym?</p> <h2>What determines ‘taste’?</h2> <p>Taste is a complex system we evolved to help us navigate the environment. It helps us select foods with nutritional value and reject anything potentially harmful.</p> <p>Foods are made up of different compounds, including nutrients (such as proteins, sugars and fats) and <a href="https://www.youtube.com/watch?v=2P_0HGRWgXw">aromas</a> that are detected by sensors in the mouth and nose. These sensors create the <a href="https://www.youtube.com/watch?v=MZn2PMUWO-Y">flavour of food</a>. While taste is what the tastebuds on your tongue pick up, flavour is the combination of how something smells and tastes. Together with texture, appearance and sound, these senses collectively influence your food preferences.</p> <figure><iframe src="https://www.youtube.com/embed/MZn2PMUWO-Y?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Flavour is the overall impression you get when eating.</span></figcaption></figure> <p>Many factors influence food preferences, including age, genetics and environment. We each live in our own sensory world and no two people will have the same <a href="https://theconversation.com/curious-kids-why-do-some-people-find-some-foods-yummy-but-others-find-the-same-foods-yucky-77671">experience while eating</a>.</p> <p>Food preferences also change with age. Research has found young children have a <a href="https://pubmed.ncbi.nlm.nih.gov/24452237/">natural preference</a> for sweet and salty tastes and a dislike of bitter tastes. As they grow older their ability to like bitter foods grows.</p> <p>Emerging evidence shows bacteria in saliva can also produce enzymes that influence the taste of foods. For instance, saliva has been shown to cause the release of sulphur aromas in cauliflower. The <a href="https://www.acs.org/pressroom/presspacs/2021/acs-presspac-september-22-2021/childrens-dislike-of-cauliflower-broccoli-could-be-written-in-their-microbiome.html">more sulphur that is produced</a>, the less likely a kid is to enjoy the taste of cauliflower.</p> <h2>Nature versus nurture</h2> <p>Both genetics and the environment play a crucial role in determining food preferences. Twin studies estimate genetics have a moderate influence on food preferences (between 32% and 54%, depending on the food type) in <a href="https://www.sciencedirect.com/science/article/pii/S000291652305027X?via%3Dihub">children</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/27385609/">adolescents</a> and <a href="https://www.cambridge.org/core/journals/twin-research-and-human-genetics/article/dietary-patterns-and-heritability-of-food-choice-in-a-uk-female-twin-cohort/8507AAF01330C599BAC62BCC0EF4CF06">adults</a>.</p> <p>However, since our cultural environment and the foods we’re exposed to also shape our preferences, these <a href="https://pubmed.ncbi.nlm.nih.gov/24452237/">preferences are learned</a> to a large degree.</p> <p>A lot of this learning takes place during childhood, at home and other places we eat. This isn’t textbook learning. <a href="https://www.cabidigitallibrary.org/doi/10.1079/9780851990323.0093">It’s learning</a> by experiencing (eating), which typically leads to increased liking of the food – or by watching what others do (modelling), which can lead to both positive or negative associations.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S000291652305027X?via%3Dihub">Research</a> has shown how environmental influences on food preferences change between childhood and adulthood. For children, the main factor is the home environment, which makes sense as kids are more likely to be influenced by foods prepared and eaten at home. Environmental factors influencing adults and adolescents are more varied.</p> <h2>The process of ‘acquiring’ taste</h2> <p>Coffee and beer are good examples of bitter foods people “acquire” a taste for as they grow up. The ability to overcome the dislike of these is largely due to:</p> <ul> <li> <p>the social context in which they’re consumed. For example, in many countries they may be associated with passage into adulthood.</p> </li> <li> <p>the physiological effects of the compounds they contain – caffeine in coffee and alcohol in beer. Many people find these effects desirable.</p> </li> </ul> <p>But what about acquiring a taste for foods that don’t provide such desirable feelings, but which are good for you, such as kale or fatty fish? Is it possible to gain an acceptance for these?</p> <p>Here are some strategies that can help you learn to enjoy foods you currently don’t:</p> <ol> <li> <p>eat, and keep eating. Only a small portion is needed to build a liking for a specific taste over time. It may take 10–15 attempts or more before you can say you “like” the food.</p> </li> <li> <p><a href="https://www.sciencedirect.com/science/article/pii/S0950329302001106">mask bitterness</a> by eating it with other foods or ingredients that contain salt or sugar. For instance, you can pair bitter rocket with a sweet salad dressing.</p> </li> <li> <p>eat it repeatedly in a positive context. That could mean eating it after playing your favourite sport or with people you like. Alternatively, you could eat it with foods you already enjoy; if it’s a specific vegetable, try pairing it with your favourite protein.</p> </li> <li> <p>eat it when you’re hungry. In a hungry state you’ll be more willing to accept a taste you might not appreciate on a full stomach.</p> </li> <li> <p>remind yourself why you want to enjoy this food. You may be changing your diet for health reasons, or because you’ve moved countries and are struggling with the local cuisine. Your reason will help motivate you.</p> </li> <li> <p>start young (if possible). It’s easier for children to learn to like new foods as their tastes are less established.</p> </li> <li> <p>remember: the more foods you like, the easier it’ll become to learn to like others.</p> </li> </ol> <p>A balanced and varied diet is essential for good health. <a href="https://www.sciencedirect.com/science/article/pii/S0195666315003438?ref=pdf_download&amp;fr=RR-2&amp;rr=82a5fd5069821f63">Picky eating</a> can become a problem if it leads to vitamin and mineral deficiencies – especially if you’re avoiding entire food groups, such as vegetables. At the same time, eating too many tasty but energy-dense foods can increase your risk of chronic disease, including obesity.</p> <p>Understanding how your food preferences have formed, and how they can evolve, is a first step to getting on the path of healthier eating.<!-- Below is The Conversation's page counter tag.

6 natural remedies for tinnitus

<p>As anyone who’s ever experienced will agree, tinnitus is about as fun as repeatedly stubbing your big toe. But the good news is needn’t suffer in silence. There is a range of natural remedies available, and while these won’t eliminate tinnitus completely they may be used to help manage the condition.</p> <p>Before we go through some of the natural remedies, it might be useful to take a moment to understand what tinnitus actually is. Tinnitus is a physical condition that is usually caused by a fault in the hearing system where someone experiences noises or ringing in their ears when there is no external noise presents. It’s important to know tinnitus is symptom, and not a disease. It can be caused by a variety of things including exposure to loud noises, earwax blockages, ear-bone changes and age-related hearing lost. Approximately one in five Australians suffer from tinnitus.</p> <p><strong>1. Gingko biloba</strong></p> <p>Across the board, gingko biloba is generally considered one of the stronger herbal remedies for tinnitus. This widely available herbal remedy is often used to improve blood circulation, which can reduce the ringing sensation and improve the function of your ears. It also contains handy antibacterial and antifungal properties that can help eliminate any existing infections.</p> <p><strong>2. Apple cider vinegar</strong></p> <p>Apple cider vinegar provides a particularly useful daily tonic to help reduce the effects of tinnitus. A natural antifungal and anti-inflammatory agent, apple cider vinegar also works to alkalize your body and help rebalance your internal levels. Again, this remedy is quite helpful when it comes to getting rid of any underlying infections or fungus that may be contributing to your tinnitus.</p> <p><strong>3. Alpha lipoic acid</strong></p> <p>Alpha lipoic acid provides tinnitus sufferers with another handy supplement that can help minimise the effects of this condition. Functioning as an antioxidant, this vitamin-like chemical is known to help treat cell damage and restore natural vitamin levels in your body. Alpha lipoic acid has also been known to help improve neuron function and conduction, which may be contributing factors.</p> <p><strong>4. Holy basil</strong></p> <p>Here’s another natural remedy for treating tinnitus. Holy basil is known to contain a range of antibacterial properties and can be used to help kill the bacteria that may be contributing to the problem. In addition, holy basil can also be used as a way to provide you with relief from more severe forms of ear pain. It won’t solve the problem, but it will make it easier to manage.</p> <p><strong>5. Onions and garlic</strong></p> <p>While they might not make your breath smell the best on a hot date, onions and garlic have been used in the past to provide relief for tinnitus sufferers. Onions contain medicinal and antibacterial properties to help fight infections, while garlic can help reduce inflammation and improve blood circulation, which is particularly useful for tinnitus that is caused by high altitudes.</p> <p><strong>6. Saline solution</strong></p> <p>Here’s another nifty way to treat tinnitus naturally. Saline solution can help clear any blocked nasal passages and ease the pressure caused by excessive fluids that are building up in your sinuses. This simple remedy is a great way to provide effective relief from particular forms of tinnitus. </p> <p>So there you go, six handy ways to help relive yourself of the effects of tinnitus. Ultimately we would recommend that you go to a doctor and get a proper diagnosis if you happen to be suffering from tinnitus, but at the very least it’s handy to know that these natural remedies are around.</p> <p><em>Image credits: Getty Images</em></p>

It is a vital part of many ecosystems and cultures. Yet human activities in the current era, sometimes called the “<a href="https://theconversation.com/did-the-anthropocene-start-in-1950-or-much-earlier-heres-why-debate-over-our-world-changing-impact-matters-209869">Anthropocene</a>”, are reshaping patterns of fire across the planet.</p> <p><a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">In our new research</a>, published in the Annual Review of Environment and Resources, we used satellite data to create global maps of where and how fires are burning. We calculated about 3.98 million square kilometres of Earth’s land surface burns each year. We also examined research spanning archaeology, climatology, ecology, Indigenous knowledge and paleoecology, to better understand the causes and consequences of fires.</p> <p>Our international team found strong evidence fires are burning in unexpected places, at unusual times and in rarely observed ways. These changes in fire patterns are threatening human lives and modifying ecosystems.</p> <p>But the future does not have to be bleak. There are many opportunities to apply knowledge and practice of fire to benefit people and nature.</p> <h2>Here’s how fire patterns are changing</h2> <p>Exploring multiple approaches and scales enables a deeper understanding of where, when and how fires burn.</p> <p>Satellite data provide evidence of changes in fire patterns at a global scale. <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2020RG000726">Annual fire season length</a> increased by 14 days from 1979 to 2020 and <a href="https://www.nature.com/articles/s41586-021-04325-1">night fires</a>, which indicate fires that cannot be quickly controlled, increased in intensity by 7.2% from 2003 to 2020.</p> <p>Other changes are apparent only when we look at data from particular regions. An increase in fire size and the frequency of large fires has recently been observed in <a href="https://www.pnas.org/doi/abs/10.1073/pnas.2103135118">forests and woodlands of the western United States</a>. Meanwhile fire-dependent grasslands and savannahs across <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/gcb.14711">Africa</a> and <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2019GL082327">Brazil</a> have experienced reductions in fire frequency.</p> <p>It’s also important to consider the timescale and type of fire when interpreting changes. In Australia, <a href="https://www.nature.com/articles/s41467-021-27225-4">satellite records show</a> the frequency of very large forest fires has increased over the past four decades. At longer time scales, <a href="https://link.springer.com/article/10.1007/s13280-020-01339-3">charcoal and pollen records</a> indicate the frequency of low-intensity fires <a href="https://esajournals.onlinelibrary.wiley.com/doi/10.1002/fee.2395">decreased in parts of southeastern Australia</a> following British colonisation in 1788.</p> <h2>Changes in fire affect air, land and water</h2> <p>Many animals and plants have evolved strategies that enable them to thrive under particular fire patterns. This means changes to fire characteristics can <a href="https://www.science.org/doi/10.1126/science.abb0355">harm populations and ecosystems</a>.</p> <p><a href="https://conbio.onlinelibrary.wiley.com/doi/full/10.1111/conl.12905">Large and intense fires</a> are reducing the available forest habitat preferred by the greater glider. But a <a href="https://theconversation.com/research-reveals-fire-is-pushing-88-of-australias-threatened-land-mammals-closer-to-extinction-185965">lack of fire can be problematic too</a>. Threatened species of native rodents can benefit from food resources and habitats that flourish shortly after fire.</p> <p>There is evidence that emissions from recent fires are already modifying the atmosphere. The historically exceptional 2019–20 Australian wildfires produced <a href="https://www.science.org/doi/10.1126/science.abe1415#:%7E:text=Intense%2C%20widespread%20bushfires%20in%20Australia,from%20a%20moderate%20volcanic%20eruption.">record-breaking levels of aerosols</a> over the Southern Hemisphere, as well as substantial carbon emissions.</p> <p>The <a href="https://www.nature.com/articles/s41893-020-00610-5">wildfire smoke-related health costs</a> of the 2019–20 wildfires in Australia included an estimated 429 smoke-related premature deaths as well as 3,230 hospital admissions for cardiovascular and respiratory disorders.</p> <p>Changes in fire patterns are modifying water cycles, too. In the western United States, <a href="https://www.pnas.org/doi/10.1073/pnas.2009717118">fires are reaching higher elevations</a> and having strong impacts on <a href="https://www.pnas.org/doi/10.1073/pnas.2200333119">snow</a> and water availability.</p> <p>New studies are revealing how the air, land and water that support life on Earth are connected by fires. Smoke plumes from the 2019–20 Australian wildfires transported nutrients to the Southern Ocean, resulting in <a href="https://www.nature.com/articles/s41586-021-03805-8">widespread phytoplankton blooms</a>.</p> <h2>Humans are responsible for the changes</h2> <p>Human drivers such as climate change, land use, fire use and suppression, and transportation and extinction of species <a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">are causing shifts in fire patterns</a>.</p> <p>Increasing global temperatures and more frequent heatwaves and droughts increase the likelihood of fire by promoting hot, dry and windy conditions. A pattern of extreme fire weather outside of natural climate variation is already emerging in <a href="https://onlinelibrary.wiley.com/doi/10.1111/gcb.15388">North America</a>, <a href="https://link.springer.com/article/10.1007/s10584-014-1183-3">southern Europe</a> and <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ac1e3a/meta">the Amazon basin</a>.</p> <p>Humans modify fire regimes by changing land use for agricultural, forestry and urban purposes. Until recent decades, large fires in tropical forests were uncommon. But <a href="https://www.nature.com/articles/s41586-021-03876-7">deforestation fires</a> used to clear primary forest for agriculture often promotes more frequent and intense uncontrolled fires.</p> <p>Humans have transported plants and animals across the globe, resulting in novel mixes of species that modify fuels and fire regimes. In many parts of the world, <a href="https://www.pnas.org/doi/abs/10.1073/pnas.1908253116">invasive grasses</a> have increased flammability and fire activity.</p> <p>Social and economic changes propel these drivers. Colonisation by Europeans and the displacement of Indigenous peoples and their skilful use of fire has been linked with fire changes in <a href="https://esajournals.onlinelibrary.wiley.com/doi/10.1002/fee.2395">Australia</a>, <a href="https://www.pnas.org/doi/10.1073/pnas.2116264119">North America</a> and <a href="https://royalsocietypublishing.org/doi/10.1098/rstb.2015.0174">South America</a>.</p> <h2>Using knowledge and practice of fire to achieve sustainability goals</h2> <p><a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">The pace and scale of these changes</a> represent challenges to humanity, but knowledge and practice of fire can help to achieve sustainability goals.</p> <p>This includes:</p> <ul> <li><a href="https://royalsocietypublishing.org/doi/10.1098/rstb.2015.0174">good health and wellbeing</a>, by supporting community-owned solutions and fire practices that increase social cohesion and health</li> <li><a href="https://www.sciencedirect.com/science/article/pii/S0301479718314658">sustainable cities and communities</a>, by designing green firebreaks and mixed-use areas with low fuels, strategically located in the landscape</li> <li><a href="https://www.science.org/doi/10.1126/science.aam7672">life on land</a>, by tailoring use of fire to promote and restore species and ecosystems</li> <li><a href="https://www.nature.com/articles/s41561-021-00867-1">climate action</a>, by applying low-intensity fire to promote the stability of soil organic matter and increase carbon storage</li> <li><a href="https://www.mdpi.com/1660-4601/18/8/3921">reduced inequalities</a>, by allocating resources before, during, and after wildfires to at-risk communities and residents.</li> </ul> <p>As the world changes, society as a whole needs to keep learning about the interplay between people and fire.</p> <p>A deep understanding of fire is essential for achieving a sustainable future – in other words, <a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">a better Anthropocene</a>.<!-- Below is The Conversation's page counter tag.

If the world were coming to an end, what would be the most ethical way to rebuild humanity ‘off planet’?

<p><em><a href="https://theconversation.com/profiles/evie-kendal-734653">Evie Kendal</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>Last week, scientists announced that for the first time on record, Antarctic ice has failed to “substantially recover” over winter, in a “once in 7.5-million-year event”. Climate change is the <a href="https://theconversation.com/antarctica-is-missing-a-chunk-of-sea-ice-bigger-than-greenland-whats-going-on-210665">most likely culprit</a>.</p> <p>Petra Heil, a sea ice physicist from the Australian Antarctic Division, <a href="https://www.abc.net.au/news/2023-07-24/antarctic-sea-ice-levels-nosedive-five-sigma-event/102635204">told the ABC</a> it could tip the world into a new state. “That would be quite concerning to the sustainability of human conditions on Earth, I suspect.”</p> <p>And in March, a senior United Nations disarmament official <a href="https://press.un.org/en/2023/sc15250.doc.htm">told the Security Council</a> the risk of nuclear weapons being used today is higher than at any time since the end of the Cold War.</p> <p>Both warnings speak to concerns about Earth’s security. Will our planet be able to support human life in the future? And if not, will humanity have another chance at survival in space?</p> <h2>‘Billionauts’ and how to choose who goes</h2> <p>Over the past few years, we’ve witnessed the rise of the “billionaut”. The ultra-wealthy are engaged in a <a href="https://theconversation.com/billionaire-space-race-the-ultimate-symbol-of-capitalisms-flawed-obsession-with-growth-164511">private space race</a> costing billions of dollars, while <a href="https://www.forbes.com/sites/oliverwilliams1/2021/12/21/billionaire-space-race-turns-into-a-publicity-disaster/?sh=79056f7e5e4d">regular citizens often condemn</a> the wasted resources and contribution to global carbon emissions.</p> <p>Space – described in the <a href="https://www.unoosa.org/oosa/en/ourwork/spacelaw/treaties/introouterspacetreaty.html">Outer Space Treaty</a> as being the “province of all mankind” – risks instead becoming the playground of the elite few, as they try to escape the consequences of environmental destruction.</p> <p>But if we have to select humans to send into space for a species survival mission, how do we choose who gets to go?</p> <p>In Montreal last month, the <a href="https://irg.space/irg-2023/">Interstellar Research Group</a> explored the question: how would you select a crew for the first interstellar mission?</p> <p>A panel led by <a href="https://www.erikanesvold.com/">Erika Nesvold</a>, a co-editor of the new book <a href="https://global.oup.com/academic/product/reclaiming-space-9780197604793?cc=au&amp;lang=en&amp;">Reclaiming Space</a>, discussed the perspectives of gender minorities, people with disabilities and First Nations groups regarding the ideal composition for an off-world crew.</p> <p>I was on the panel to discuss my contribution to the book, which explores how we can promote procreation in our new off-world society, without diminishing the reproductive liberty of survivors.</p> <h2>The ultra-wealthy and reproductive slavery</h2> <p>The first step in deciding how to allocate limited spaces on our “lifeboat” is identifying and rejecting options that are practically or ethically unacceptable.</p> <p>The first option I rejected was a user-pay system, whereby the wealthy can purchase a seat on the lifeboat. A 2022 Oxfam report showed the investments of just 125 billionaires collectively contribute 393 million tonnes of carbon dioxide equivalent per year: <a href="https://www.oxfam.org/en/press-releases/billionaire-emits-million-times-more-greenhouse-gases-average-person#:%7E:text=Recent%20data%20from%20Oxfam's%20research,%C2%B0C%20goal%20of%20the">a million times more</a> than the average for most global citizens.</p> <p>If the ultra-wealthy are the only ones to survive an environmental apocalypse, there’s a risk they would just create another one, on another planet. This would undermine the species survival project.</p> <p>The second option I rejected was allowing a reproductive slave class to develop, with some survivors compelled to populate the new community. This would disproportionately impact cis-gender women of reproductive capacity, demanding their gestational labour in exchange for a chance at survival.</p> <p>Neither a user-pay system nor reproductive slave labour would achieve the goal of “saving humanity” in any meaningful way.</p> <p>Many would argue preserving human values - including equality, reproductive liberty, and respect for diversity - is more important than saving human biology. If we lose what makes us unique as a species, that would be a kind of extinction anyway.</p> <p>But if we want humanity to survive, we still need to build our population in our new home. So what other options do we have?</p> <h2>Reproduction and diversity</h2> <p>How can we avoid discrimination on the basis of reproductive capacity – including age, sexuality, <a href="https://theconversation.com/infertility-through-the-ages-and-how-ivf-changed-the-way-we-think-about-it-87128">fertility status</a> or personal preference?</p> <p>We could avoid any questions about family planning when selecting our crew. This would align with <a href="https://www.seek.com.au/career-advice/article/illegal-interview-questions-what-employers-have-no-right-to-ask">equal opportunity policies</a> in other areas, like employment. But we would then have to hope enough candidates selected on other merits happen to be willing and able to procreate.</p> <p>Alternatively, we could reserve a certain number of places for those who agree to contribute to population growth. Fertility would then become an inherent job requirement. This might be similar to taking on a role as a <a href="https://theconversation.com/surrogacy-laws-why-a-global-approach-is-needed-to-stop-exploitation-of-women-98966">surrogate</a>, in which reproductive capacity is essential.</p> <p>But what if, after accepting such a position on the mission, someone changed their mind about wanting children? Would they be expected to provide some sort of compensation? Would they be vulnerable to retaliation?</p> <p>The more we focus on procreation, the less diversity we will preserve in the species as a whole – especially if we deliberately select against diverse sexualities, disabilities and older people.</p> <p>A lack of diversity would also threaten the long-term viability of the new society. For example, even if we exclude all physiologically or socially infertile people from the initial crew, these traits will reappear in future generations.</p> <p>The difference is: these children would be born into a less accepting community. Cooperation will be essential for the new human society – so promoting hostility would be counterproductive.</p> <p>So, what options are left? Using a random global sample to select travellers might alleviate concerns about equity and fairness. But the ability of a random sample to maximise our survival as a species would depend on how large the sample can be.</p> <p>A global sample would minimise bias. But there’s a risk it might yield a crew without doctors, engineers, farmers or other essential personnel.</p> <h2>Random selection versus a points-based system</h2> <p>The best balance between competing needs might be a stratified random sampling method, involving randomly selecting survivors from predetermined categories. Reproductive potential might be one category. Others might focus on other elements of practical usefulness or contribution to human diversity.</p> <p>Another option is a points-based system, whereby different skills and characteristics are ranked in terms of their desirability. In this system, an elderly person who speaks multiple languages may score higher than a physiologically fertile young person, due to their ability to substantially contribute to language preservation and education.</p> <p>This does not entirely eliminate the potential for discrimination, of course. Someone would need to decide which traits are most desirable and valuable to the new human society.</p> <p>However we determine our lifeboat candidates, it should be carefully considered. In our attempt to “save humanity”, we must avoid sacrificing the very things that make us human.</p> <hr /> <p><em>Evie Kendal is a contributor to <a href="https://global.oup.com/academic/product/reclaiming-space-9780197604793?cc=au&amp;lang=en&amp;">Reclaiming Space: Progressive and Multicultural Visions of Space Exploration</a> (Oxford University Press)<!-- Below is The Conversation's page counter tag.

Human remains found in search for missing teenager

<p>Tasmanian Police have discovered human remains in their search for missing 14-year-old Shyanne-Lee Tatnell.</p> <p>After a huge ground and air search, the remains were found on a bush track at Nabowla, in the north-east of Tasmania. </p> <p>While police have yet to confirm the remains are those of the missing teen, they have notified Shyanne-Lee's parents of the discovery. </p> <p>Shyanne-Lee went missing almost three months ago on April 30th, and was last seen on a main road in Launceston. </p> <p>Northern District Commander Kate Chambers said a crime scene had been declared where the remains were found. </p> <p>"It is with a heavy heart that I can confirm that remains were located late this afternoon during our extensive search. While these have not yet been forensically confirmed, they are believed to be human remains," Chambers said.</p> <p>"We have been in regular contact with Shyanne-Lee's family throughout the investigative process, and have notified them about this latest development." </p> <p>"Our thoughts continue to be with them and Shyanne-Lee's loved ones during this difficult time."</p> <p>Police went on to confirm that no arrests have been made, but declared that the investigation into Shyanne-Lee's disappearance now likely had a “criminal element” as they are “following a specific line of inquiry".</p> <p>Tasmania Police, with the assistance of NSW Police, the Australian Federal Police, SES and community volunteers, launched what’s believed to be Northern Tasmania’s largest police operation on Wednesday in the search for clues as to Shyanne-Lee’s whereabouts.</p> <p><em>Image credits: Facebook / Tasmania Police</em></p>

10 reasons humans kill animals – and why we can’t avoid it

<p><em><a href="https://theconversation.com/profiles/benjamin-allen-100036">Benjamin Allen</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069"><em>University of Southern Queensland</em></a></em></p> <p>As long as humans have existed, they’ve killed animals. But the necessity of some types of animal killing are now questioned by many. So can humans ever stop killing animals entirely? And if not, what’s the best way forward?</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062">New research</a> I led investigates these questions. My colleagues and I identified the ten main reasons why humans kill animals. We found the need for some types of animal killing is questionable, but several forms are inescapable – a necessary part of humanity’s involvement in a single, functioning, finite global food web.</p> <p>But the debate doesn’t end there. Even if humans must kill animals in some cases, they can modify their behaviours to improve the welfare of animals while they are alive, and to reduce an animal’s suffering when it is killed.</p> <p>Doing so may improve the lives of animals to a greater extent than efforts to eliminate human killing entirely.</p> <h2>Why humans kill animals</h2> <p>Critics of animal-killing come from a variety of perspectives. Some oppose it on <a href="http://refhub.elsevier.com/S0048-9697(23)03906-2/rf0005">moral grounds</a>. Others claim animals should have <a href="https://conbio.onlinelibrary.wiley.com/doi/10.1111/cobi.13494">rights equal</a> to humans, and say animal killing is a criminal act. Many people view any animal killing as <a href="https://conbio.onlinelibrary.wiley.com/doi/10.1111/cobi.13126">cruel</a>, regardless of whether the animal suffers.</p> <p>But as valid and important as these views might be, they largely fail to address <em>why</em> humans kill animals – and why in many cases, it can’t be avoided. Our research sought to shed light on this.</p> <p>We focus our discussion on vertebrate animals which are almost universally recognised as “sentient” (or able to perceive and feel things). We identified ten main reasons humans kill animals:</p> <p><strong>1. Wild harvest or food acquisition:</strong> such as killing wild animals for meat</p> <p><strong>2. Human health and safety:</strong> such as reactively killing an animal when it attacks you</p> <p><strong>3. Agriculture and aquaculture:</strong> such as killing that occurs in the global meat industries, or killing required to produce crops</p> <p><strong>4. Urbanisation and industrialisation:</strong> such as clearing bushland to build homes</p> <p><strong>5. Wildlife control:</strong> such as programs that eradicate introduced animals to stop them killing native ones</p> <p><strong>6. Threatened species conservation:</strong> such as unintentionally killing animals when relocating them</p> <p><strong>7. Recreation, sport or entertainment:</strong> such as trophy hunting or bull fighting, and animal killing required to feed domestic pets</p> <p><strong>8. Mercy or compassion:</strong> such as euthanasing an animal hit by a car</p> <p><strong>9. Cultural and religious practice:</strong> such as animal sacrifice during the Islamic celebration of <a href="https://www.theguardian.com/world/2023/jul/01/sydney-muslims-take-eid-al-adha-livestock-sacrifice-into-their-own-hands">Eid al-Adha</a>, or those associated with the <a href="https://www.jstor.org/stable/1594756">Yoruba</a> religion of West Africa</p> <p><strong>10. Research, education and testing:</strong> such as the laboratory use of rodents or primates.</p> <h2>Understanding human killing behaviour</h2> <p>So how best should we understand the above types of animal killing? Our research considers them in ecological terms – as behaviours consistent with our predatory and competitive roles in the global food web. Such behaviours are intended to improve human prospects for acquiring food or to protect and enhance life. These are innate life objectives for any sentient animal.</p> <p>Maintenance of all life on Earth requires obtaining, using, disposing of and recycling chemical elements. Ecosystems can be thought of as a “battleground” for these elements.</p> <p><a href="https://theconversation.com/peter-singers-fresh-take-on-animal-liberation-a-book-that-changed-the-world-but-not-enough-205830">Some people argue</a> that directly killing animals is unacceptable, or that adopting certain lifestyles or diets, such as veganism, can eliminate or greatly reduce animal killing. But in our view, achieving a no-killing lifestyle is a physical and ecological impossibility.</p> <p>For instance, most plant foods come from crops grown on land where animals have been <a href="https://www.mdpi.com/2076-2615/11/5/1225">killed or displaced</a>. And while an animal-free diet for humans might temporarily reduce the number of animals killed, this won’t last forever. As human populations continue to grow, more land will eventually be needed to meet their food requirements. At that point, humans will have to directly or indirectly kill animals again or risk dying themselves.</p> <p>Humans also need space to live, which <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&amp;fr=RR-2&amp;rr=7e2e8f44ae1aaae3#bbb1045">results in</a> animal killing when habitat is razed.</p> <p>Of course, in rare cases an individual human may live without killing animals directly. Perhaps they live in a cave in the forest, and get sustenance from wild berries and mushrooms. But that human still lives inside the food web, and is competing against other animals for finite resources. In these cases, other animals may suffer and die because the human’s use of berries and caves leaves less food and space for them.</p> <p>Even if that human could do no harm at all to any animal, it’s still impossible for societies at large to live in this way.</p> <p>Some forms of animal killing are certainly not essential for human existence. Good examples are recreational hunting, euthanasia or keeping pets (which requires killing animals to feed them). And we certainly do not condone direct human participation in all forms of animal killing.</p> <p>It’s also important to note that in many cases, current levels of animal killing are <a href="https://www.opsociety.org/stop-unsustainable-fishing/">unsustainable</a>. Human populations have increased to the point where animals must be killed on enormous scales to feed, house and protect ourselves. If this continues, animal <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&amp;fr=RR-2&amp;rr=7e2e8f44ae1aaae3#bbb0905">populations</a> will <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&amp;fr=RR-2&amp;rr=7e2e8f44ae1aaae3#bbb0910">crash</a> – and with them, human populations.</p> <p>Nevertheless, we maintain that the overall necessity of animal killing is an unavoidable reality for humanity as a whole. A variety of direct and indirect forms of animal killing will undoubtedly remain an ongoing human endeavour.</p> <h2>Taking responsibility</h2> <p>So what are the implications of all this? We hope our research leads to a constructive dialogue, which starts with accepting that human existence on Earth is dependent on animal killing. It should then focus on the nuances of animal welfare and sustainability.</p> <p>Humans are the only known animals with an ethical or moral conscience. That means we have <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&amp;fr=RR-2&amp;rr=7e2e8f44ae1aaae3#bbb0650">a responsibility</a> to assume a stewardship role over all other animals, to resolve negative interactions between them as best as possible, and to ensure good welfare for as many animals as we can.</p> <p>Directing our attention in this way is likely to improve the lives of animals to a greater extent than trying to prevent humans from killing animals altogether – efforts my colleagues and I believe will ultimately be in vain.<!-- Below is The Conversation's page counter tag.

"Possibly carcinogenic to humans": WHO's dire warning over common ingredient

<p dir="ltr">The World Health Organisation (WHO) has called for one of the world’s most popular artificial sweeteners to be declared a possible carcinogen. </p> <p dir="ltr">The push will be led by the WHO’s research team for the International Agency for Research on Cancer (IARC), pitting it against the food industry and regulators.</p> <p dir="ltr">The sweetener, known as Aspartame, is used in products from Coca-Cola diet drinks, such as Diet Coke and Coke Zero, to Mars’ Extra chewing gum and some Snapple drinks.</p> <p dir="ltr">Later this month, the IARC will list Aspartame for the first time as “possibly carcinogenic to humans”</p> <p dir="ltr">The ruling from the IARC has assessed whether the sweetener is hazardous to humans or not, although it does not stipulate how much of the product a person can safely consume. </p> <p dir="ltr">This advice for individual consumers comes from a different organisation, known as JECFA (the Joint WHO and Food and Agriculture Organisation’s Expert Committee on Food Additives), who make consumption guidelines alongside national regulators. </p> <p dir="ltr">Despite the claims from the WHO, since as early as 1981 JECFA has said aspartame is safe to consume within accepted daily limits.</p> <p dir="ltr">An adult weighing 60kg would have to drink between 12 and 36 cans of diet soft drink, depending on the amount of aspartame in the beverage, every day to be at risk.</p> <p dir="ltr">Its view has been widely shared by national regulators, including in the United States and Europe.</p> <p dir="ltr">These conflicting reports have angered some regulators and consumers alike, with Japan’s Ministry of Health, Labour and Welfare official Nozomi Tomita writing to the WHO, “kindly asking both bodies to coordinate their efforts in reviewing aspartame to avoid any confusion or concerns among the public.”</p> <p dir="ltr"><em>Image credits: Getty Images</em></p>
