“Hypocrite”: Hughesy's on-air clash with Greens leader

Dave “Hughesy” Hughes had a fiery debate with Australian Greens Leader Adam Bandt about veganism on-air on The Fox’s Fifi, Fev & Nick. Before Bandt appeared on the show, a clip played of Hughesy, who is a vegan, calling for the leader to "quit the party" after learning the Greens leader wasn't a vegan. He questioned how Bandt could advocate for climate action without adopting a plant-based lifestyle, and the Greens leader was brought onto the show to explain his stance. “So you are not a vegan?” Hughesy asked the politician. “I’m not….” replied Bandt. “I applaud those who are, I applaud those who have made the shift. I’ve been thinking about it …” Hughesy then loudly interjected “ … URGH, THINKING ABOUT IT?” The Greens leader replied: “I don’t have a good drop-dead reason, but I’ve been thinking about it, and I can probably give you three justifications for it. "Firstly, we’ve made big changes at home and basically only eat meat for special occasions, the rest of the time we’re vegan or vegetarian at home.” “…. THERE’S ONE WAY, ADAM, THERE’S ONE WAY …” the presenter yelled in response. Hughesy's co-star Fev then tried to make light of the situation and asked him: “What are you doing Dave?" "Adam is doing the version of Leonardo DiCaprio and his private jet flying around the world while banging on about climate change, but you flew to Brisbane on the weekend,” he continued suggesting that Hughesy too was being a hypocrite by getting on a flight recently. “But I don’t bang on about it,” exclaimed Hughesy. “Adam is the leader of the Greens … it’s hypocritical! C’mon, you can do it, Adam, you can become a vegan! Be the change you want to see in the world, buddy!” Hughesy adopted the vegan lifestyle for his own health, but he has previously revealed that it comes with its challenges and his family were also not that enthusiastic about the change.

Walking or running: for the same distance, which consumes more energy?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/clement-lemineur-1529211">Clément Lemineur</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a>; <a href="https://theconversation.com/profiles/clement-naveilhan-1495411">Clément Naveilhan</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a>, and <a href="https://theconversation.com/profiles/francois-dernoncourt-1495410">François Dernoncourt</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a> It’s Monday morning, the alarm goes off and it’s already 7:30 a.m. – and you’re 30 minutes late. Normally you need 45 minutes to walk the 3 kilometres to work, but this morning you’ll be running for 20 minutes. Yes, but by lunchtime you’re feeling more tired and you have the impression that you’ve expended more energy than usual on the trip. Yet you’ve covered the same distance as on the other days. How can this be? The calorie expenditure associated with any activity is called the “metabolic cost”, and corresponds to the energy consumed by our organs to cover a given distance. This metabolic cost can be determined by analysing the oxygen our bodies consume and the carbon dioxide they produce, we can estimate the amount of energy expended, and thus the metabolic cost. It was using this method that <a href="https://pubmed.ncbi.nlm.nih.gov/692303/">researchers had already answered our question back in the 1970s</a>. Perhaps not surprisingly, running consumes more energy than walking for the same distance covered. But why? <h2>Energy lost when running</h2> Imagine you’re watching someone running. Now look closely at the vertical movement (up and down) of their pelvis and head. As you can see from the diagram below, when we run, the distance that our body moves up and down is greater than when we walk. To produce this vertical movement, the muscles of the lower limbs have to generate more force, and that consumes more energy, yet doesn’t bring us any closer to our destination. So when running, part of the energy expended is used to move our bodies <a href="https://pubmed.ncbi.nlm.nih.gov/16029949/">upward rather than forward</a>. The energy needed to cover those 3 km is therefore higher for running than for walking. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=287&fit=crop&dpr=1 600w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=287&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=287&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=361&fit=crop&dpr=1 754w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=361&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=361&fit=crop&dpr=3 2262w" alt="Illustration of the oscillations of running and walking" /></a><figcaption>Running involves much greater vertical oscillation of the centre of mass than walking. This is the main reason why running consumes more energy than walking for the same distance covered. François Dernoncourt, Fourni par l'auteur</figcaption></figure> This difference between walking and running is not confined to what happens during the activity itself. In fact, each physical exercise causes a delayed expenditure of energy, which is added to the expenditure during the activity. Taking this into account, it’s once again running that uses more energy than walking. Immediately after running your 3 km, the increased energy consumption (compared with resting) lasts for several minutes, mainly because of the increase in body temperature and the replenishment of energy reserves. This additional expenditure after running is <a href="https://pubmed.ncbi.nlm.nih.gov/22446673/">more than twice that observed after walking</a>, due to the difference in intensity between the two exercises. <h2>It all depends on speed</h2> Running therefore involves a higher calorie expenditure than walking for the same distance covered. But this is on condition that the walking speed considered is “normal” (around 5 km/h). So, if we walk very slowly, it will take us so long to cover the 3 km that the calorie expenditure will be greater in the end. This is because the body expends a certain amount of energy per unit of time no matter what, regardless of the activity performed (known as the “basal metabolic rate”). The same applies if the walking speed is very fast (<a href="https://pubmed.ncbi.nlm.nih.gov/29925582/">more than 8 km/h</a>): running is more energy-efficient. Here, the coordination required to walk at such a speed means that we need to activate our muscles more, without being able to take advantage of the elasticity of our tendons, as is the case with running. Moreover, we have a very precise intuitive perception of the energy efficiency of a particular style of movement. If we’re on a treadmill whose speed gradually increases, the point at which we spontaneously switch from walking to running coincides with the <a href="https://www.sciencedirect.com/science/article/pii/S096663622100120X">moment when it would become more energy-consuming to walk than to run</a>. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=395&fit=crop&dpr=1 600w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=395&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=395&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=497&fit=crop&dpr=1 754w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=497&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=497&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Modelling of metabolic cost (kilocalories expended per kilogram per kilometre covered) as a function of speed (kilometres per hour) for walking and running.

How would a switch to nuclear affect electricity prices for households and industry?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/roger-dargaville-1832">Roger Dargaville</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Peter Dutton has announced that under a Coalition government, seven nuclear power stations would be built around the country over the next 15 years. Experts have declared nuclear power would be <a href="https://www.abc.net.au/news/2024-06-20/power-prices-wont-fall-with-nuclear/103998172">expensive</a> and <a href="https://www.afr.com/politics/federal/nuclear-to-cost-17b-and-take-until-2040-to-build-csiro-20240521-p5jfaj#:%7E:text=Nuclear%20could%20cost%20up%20to,until%202040%20to%20build%3A%20CSIRO&text=Peter%20Dutton's%20nuclear%20energy%20plans,operational%20until%20at%20least%202040.">slow to build</a>. But what might happen to energy prices if the Coalition were to win government and implement this plan? <h2>How might we estimate the cost of nuclear?</h2> By 2035, 50–60% of the existing coal-fired fleet will very likely <a href="https://aemo.com.au/-/media/files/stakeholder_consultation/consultations/nem-consultations/2023/draft-2024-isp-consultation/draft-2024-isp.pdf">have been retired</a>, including Vales Point B, Gladstone, Yallourn, Bayswater and Eraring – all of which will have passed 50 years old. These five generators contribute just over 10 gigawatts of capacity. It’s probably not a coincidence that the seven nuclear plants proposed by Dutton would also contribute roughly 10 gigawatts in total if built. Neither my team at Monash University nor the Australian Energy Market Operator has run modelling scenarios to delve into the details of what might happen to electricity prices under a high-uptake nuclear scenario such as the one proposed by the Coalition. That said, we can make some broad assumptions based on a metric known as the “levelised cost of electricity”. This value takes into account: <ul> <li> how much it costs to build a particular technology </li> <li> how long it takes to build </li> <li> the cost to operate the plant </li> <li> its lifetime </li> <li> and very importantly, its capacity factor. </li> </ul> Capacity factor is how much electricity a technology produces in real life, compared with its theoretical maximum output. For example, a nuclear power station would likely run at 90–95% of its full capacity. A solar farm, on the other hand, will run at just 20–25% of its maximum, primarily because it’s night for half of the time, and cloudy some of the time. CSIRO recently published its <a href="https://www.csiro.au/en/research/technology-space/energy/gencost">GenCost</a> report, which outlines the current and projected build and operational costs for a range of energy technologies. It reports that large-scale nuclear generated electricity would cost between A$155 and $252 per megawatt-hour, falling to between $136 and $226 per megawatt-hour by 2040. The report bases these costs on recent projects in South Korea, but doesn’t consider some other cases where costs have blown out dramatically. The most obvious case is that of <a href="https://www.edf.fr/en/the-edf-group/dedicated-sections/journalists/all-press-releases/hinkley-point-c-update-1">Hinkley Point C nuclear plant</a> in the United Kingdom. This <a href="https://www.reuters.com/business/energy/edfs-nuclear-project-britain-pushed-back-2029-may-cost-up-34-bln-2024-01-23/">3.2GW</a> plant, which is being built by French company EDF, was recently <a href="https://www.edf.fr/en/the-edf-group/dedicated-sections/journalists/all-press-releases/hinkley-point-c-update-1">reported</a> to be now costing around £34 billion (about A$65 billion). That’s about A$20,000 per kilowatt. CSIRO’s GenCost report assumed a value of $8,655 per kilowatt for nuclear, so the true levelised cost of electricity of nuclear power in Australia may end up being twice as expensive as CSIRO has calculated. <hr /> <iframe id="Aryx7" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/Aryx7/4/" width="100%" height="400px" frameborder="0"></iframe> <hr /> <h2>Other factors play a role, too</h2> Another factor not accounted for in the GenCost assumptions is that Australia does not have a nuclear industry. Virtually all the niche expertise would need to be imported. And very large infrastructure projects have a nasty habit of <a href="https://www.cis.org.au/publication/bungles-blowouts-and-boondoggles-why-australias-infrastructure-projects-cost-more-than-they-should/">blowing out in cost</a> – think of Snowy 2.0, Sydney’s light rail project, and the West Gate Tunnel in Victoria. Reasons include higher local wages, regulations and standards plus aversion from lenders to risk that increases cost of capital. These factors would not bode well for nuclear. In CSIRO’s GenCost report, the levelised cost of electricity produced from coal is $100–200 per megawatt-hour, and for gas it’s $120–160 per megawatt-hour. Solar and wind energy work out to be approximately $60 and $90 per megawatt-hour, respectively. But it’s not a fair comparison, as wind and solar are not “dispatchable” but are dependent on the availability of the resource. When you combine the cost of a mix of wind and solar energy and storage, along with the cost of getting the renewable energy into the grid, renewables end up costing $100–120 per megawatt-hour, similar to coal. If we were to have a nuclear-based system (supplemented by gas to meet the higher demands in the mornings and evenings), the costs would likely be much higher – potentially as much as three to four times if cost blowouts similar to Hinkley Point C were to occur (assuming costs were passed on to electricity consumers. Otherwise, taxpayers in general would bear the burden. Either way, it’s more or less the same people). <h2>But what about the impact on your household energy bill?</h2> Well, here the news is marginally better. Typical retail tariffs are 25-30 cents per kilowatt-hour, which is $250–300 per megawatt-hour. The largest component of your energy bill is not the cost of generation of the electricity; rather, it’s the cost of getting the power from the power stations to your home or business. In very approximate terms, this is made up of the market average costs of generation, transmission and distribution, as well as retailer margin and other minor costs. The transmission and distribution costs will not be significantly different under the nuclear scenario compared with the current system. And the additional transmission costs associated with the more distributed nature of renewables (meaning these renewable projects are all over the country) is included in the estimate. According to my back-of-the-envelope calculations, your retail tariff under the nuclear scenario could be 40–50c per kilowatt-hour. But if you are a large energy consumer such as an aluminium smelter, you pay considerably less per kilowatt-hour as you don’t incur the same network or retailer costs (but the cost of generating electricity in the first place makes up a much bigger proportion of the total cost). So if the cost of electricity generation soars, this hypothetical aluminium smelter’s energy costs will soar too. This would be a severe cost burden on Australian industry that has traditionally relied on cheap electricity (although it’s been a while since electricity could be described as cheap). <h2>A likely increase in energy costs</h2> In summary, in a free market, it is very unlikely nuclear could be competitive. But if a future Coalition government were to bring nuclear into the mix, energy costs for residential and especially industrial customers would very likely increase.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/232913/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/roger-dargaville-1832">Roger Dargaville</a>, Director Monash Energy Institute, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How to sign up for energy bill relief

In the face of rising living costs, thousands of Australians have turned to their energy providers for financial assistance, highlighting the community spirit and support available during these challenging times. Energy companies like AGL Australia and Energy Australia are stepping up to help their customers manage their bills and find relief. AGL Australia has seen a significant increase in its financial hardship program, with 10,000 customers joining in the past year. Energy Australia receives 1,000 calls every weekday from customers seeking bill relief. These numbers reflect the proactive measures Australians are taking to manage their expenses and the readiness of energy providers to offer support. Crystal Noronha, who has worked at the AGL call centre for 11 years, has witnessed firsthand the growing need for assistance. "There's a lot of distress in their voice, there's anxiety," Noronha <a href="https://www.9news.com.au/national/thousands-of-customers-signing-up-for-energy-bill-relief-with-millions-more-eligible/9dc9535b-f94b-42f4-aeaf-6534dc898df2" target="_blank" rel="noopener">shared with 9NEWS</a>. "Some hide away from sharing their difficulties, but we're here to help them." Customers need not face extreme financial hardship to seek help, as everyone is eligible for some form of assistance. Gavin Dufty, from the charity St Vincent De Paul, underscores the commitment of energy companies to support their customers. "Every energy company has a legal obligation to provide support for all households regardless," Dufty explains. The assistance offered varies based on the provider and individual circumstances, ranging from bill extensions and more manageable payment plans to, in some cases, complete debt waivers. Adding to this support, the federal government is taking significant steps to ease the burden on households. Starting July 1, every household will receive a $300 credit into their energy account, providing substantial relief. Additionally, a free government website is available for customers to compare energy plan prices and find the most cost-effective options. These measures reflect a collaborative effort between energy providers and the government to ensure Australians can navigate the financial challenges of today's world. By offering practical solutions and financial relief, they are making a positive impact on the lives of many, ensuring that no one is left to face these difficulties alone. Image: Getty

As part of our research on nitrate and oral health, <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0243755#:%7E:text=Nitrate%2Drich%20beetroot%20juice%20offsets,healthy%20male%20runners%20%7C%20PLOS%20ONE">we studied competitive athletes</a>. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9839431/">Athletes are prone to gum disease</a> due to high intake of carbohydrates – which can cause inflammation of the gum tissues – stress, and dry mouth from breathing hard during training. Our study showed that beetroot juice (containing approximately 12 <a href="https://www.nursingtimes.net/students/an-easy-guide-to-mmols-09-02-2012/">millimole</a> of nitrate) protected their teeth from acidic sports drinks and carbohydrate gels during exercise – suggesting that nitrate could be used as a prebiotic by athletes to reduce the risk of tooth decay. Nitrate offers a lot of promise as an oral health <a href="https://www.nature.com/articles/s41598-020-69931-x">prebiotic</a>. Good oral hygiene and a nitrate rich diet could be the key to a healthier body, a vibrant smile and disease-free gums. This is good news for those most at risk of oral health deterioration such as <a href="https://www.news-medical.net/health/Periodontitis-and-Pregnancy.aspx">pregnant women</a>, and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8771712/">the elderly</a>. In the UK, antiseptic mouthwashes containing <a href="https://www.nature.com/articles/s41598-020-61912-4">chlorhexidine</a> are commonly used to treat dental plaque and gum disease. Unfortunately, these mouthwashes are a blunderbuss approach to oral health, as they indiscriminately remove both good and bad bacteria and increase oral acidity, which can cause disease. Worryingly, early research also indicates that chlorhexidine may contribute to <a href="https://pubmed.ncbi.nlm.nih.gov/30967854/">antimicrobial resistance</a>. Resistance occurs when bacteria and fungi survive the effects of one or more <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4768623/">antimicrobial drugs</a> due to repeated exposure to these treatments. Antimicrobial resistance is a <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(21)02724-0/fulltext">global health concern</a>, predicted to cause 10 million deaths yearly by the year 2050. In contrast, dietary nitrate is more targeted. Nitrate eliminates disease-associated bacteria, reduces oral acidity and creates a balanced <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2944498/">oral microbiome</a>. The oral microbiome refers to all the microorganisms in the mouth. Nitrate offers exciting potential as an <a href="https://www.nature.com/articles/s41598-020-69931-x">oral health prebiotic</a>, which can be used to prevent disease onset or limit disease progression. <h2>How many leafy greens for pearly whites?</h2> So how much should we consume daily? As a rule of thumb, a generous helping of spinach, kale or beetroot at mealtimes contains about 6-10 mmol of nitrate and offers immediate health benefits. Work we have done with our collaborators has shown that treating <a href="https://www.nature.com/articles/s41598-020-69931-x">plaque samples</a> from periodontal disease patients with 6.5 mmol of nitrate increased healthy bacteria levels and reduced acidity. For example, consuming <a href="https://aap.onlinelibrary.wiley.com/doi/full/10.1002/JPER.20-0778">lettuce juice</a> for two weeks reduced gum inflammation and increased healthy bacteria levels in patients with gum disease. Growing evidence suggests that nitrate is a cornerstone of oral health. Crunching on a portion of vegetables at mealtimes can help to prevent or treat oral disease and keeps the mouth fresh and healthy.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221181/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/mia-cousins-burleigh-1201153">Mia Cousins Burleigh</a>, Lecturer, School of Health and Life Sciences, <a href="https://theconversation.com/institutions/university-of-the-west-of-scotland-1385">University of the West of Scotland</a> and <a href="https://theconversation.com/profiles/siobhan-paula-moran-1506183">Siobhan Paula Moran</a>, PhD candidate, School of Health and Life Sciences, <a href="https://theconversation.com/institutions/university-of-the-west-of-scotland-1385">University of the West of Scotland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Aussie grandma and former Greens candidate jailed in Japan claims she was scammed

Donna Nelson, a 57-year-old Perth grandmother, has found herself entangled in a nightmarish situation in a Japanese prison, accused of a crime she vehemently denies. Nelson, an Aboriginal health advocate and former Greens candidate, has been incarcerated for nearly a year without a trial date set, facing allegations of attempting to smuggle two kilograms of meth into Japan. However, her plight is not as straightforward as it may seem, and her family and legal team are tirelessly fighting to clear her name. The ordeal began on January 4, when Nelson was arrested at Narita Airport in Tokyo. Authorities claimed to have discovered drugs concealed within a false compartment in her luggage. According to the prosecution, a customs officer suspected her of acting suspiciously. But the narrative has taken a complex turn as Nelson's defence team unveiled a shocking revelation: she alleges she was deceived and manipulated by a Nigerian scammer who had groomed her for two years. Since her arrest, Nelson has been confined to Chibu prison, located an hour outside Tokyo. Her living conditions are appalling; she spends 23 hours a day isolated in her cell, showers are allowed only every three days, and communication with other inmates and visitors is strictly prohibited. This form of treatment is a reflection of Japan's infamous "hostage justice" strategy, aimed at coercing confessions from detainees. The only individuals granted access to Nelson are her lawyers, Australian embassy representatives, and a pastor. Legal representatives have identified a significant issue with translation throughout the case, and it could very well hinge on an inaccurate translation by the customs officer at the time of her arrest. Rie Nishida from Shinjuku International Law Firm, one of Nelson's lawyers, explained, "The main evidence from the prosecution is mainly a customs officer who said she acted suspiciously. There's a lot of mistranslation that's also the difficulty in this case." This mistranslation issue is not trivial; it extends to the messages exchanged between Nelson and the man she believed she had a romantic connection with, who ultimately turned out to be a scammer. Matthew Owens, another member of the legal team and a translator for the case, noted, "Some of them were completely wrongly translated, so we had to re-translate those messages and submit them back to the prosecutor." Nelson remains steadfast in her conviction that she is innocent of the accusations against her. Her lawyer, Owens, relayed her message, saying, "Donna wants to say that she is going to be able to prove her innocence, she's 100 per cent confident of that, and she wants everyone in Australia and the world to know she is innocent." If found guilty, Nelson could face a harrowing 20-year sentence in a Japanese prison, a terrifying prospect for both her and her family. Her five daughters and grandchildren are distraught, but they are not giving up the fight to prove her innocence. They believe they have evidence to substantiate the claim that she was scammed and unjustly accused. Image: Australian Greens

Why does my hair turn green from the swimming pool?

<a href="https://theconversation.com/profiles/magdalena-wajrak-1432339">Magdalena Wajrak</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> If you are a blonde like me and enjoy laps in a swimming pool, you may have noticed your hair acquires a green tint after frequent swims in chlorinated water. This happens to both bleached and natural blondes. In fact, the green tinge happens to everyone, but it’s less visible on dark hair and those whose hair isn’t damaged by chemical treatments such as bleaching. But what exactly causes this green discoloration, and what can we do about it? Most of us blame the chlorine in the pool water. However, although chlorine does play a part, it is not the main culprit. <h2>Which chemicals in the pool turn the hair green?</h2> The element to blame for the green staining of hair is copper. The main source of copper is copper sulfate (CuSO₄), a compound added to swimming pools to prevent the growth of algae. <a href="https://www.sciencedirect.com/science/article/pii/S1568988320301803?via%3Dihub">Contact with algae</a> can cause skin irritation and respiratory issues, and ingesting water with algae can lead to serious gastrointestinal problems. Only a small amount (around 0.5mg per litre or 0.5 parts per million) of copper sulfate is needed to prevent algal growth. However, copper can also enter swimming pools through the corrosion of water pipes, so concentrations may be higher in some pools. Copper sulfate crystals are greenish-blue in colour. So, when hair comes into contact with copper ions – a positively charged variant of a copper atom with extra electrons – those ions get absorbed by the hair and cause the greenish hue. Scientists were fascinated by the green “pool hair” phenomenon as far back as the 1970s, so we actually have research data on copper being the cause. One very <a href="https://jamanetwork.com/journals/jamadermatology/article-abstract/538197">interesting study in 1978</a> performed experiments by immersing hair samples into water containing different concentrations of copper ions, chlorine and various pH values (neutral and basic). Their results showed hair exposed to free copper ions does turn green. Furthermore, when hair is oxidised (meaning electrons are removed from the hair proteins) by chlorine, it actually damages the hair, enhancing the absorption of copper ions. Hair submerged in water with chlorine but without copper ions did not turn green. Meanwhile, hair exposed to water with only copper ions and no chlorine still formed a green colour. Hence, chlorine by itself does not play a role in causing the green hue we see in “pool hair”, but it does exacerbate it. <h2>So, how does copper get into the hair?</h2> <a href="https://doi.org/10.1007/978-1-4684-0943-7_24">Other research teams</a> have conducted <a href="https://doi.org/10.1071/ch9682437">more extensive studies</a>, using sophisticated instruments, such as scanning electron microscopy, to examine how exactly copper ions attach to the hair. Our hair is predominantly composed of protein called keratin. Keratin is classified as a “structural fibrous protein”, meaning it has an elongated, sheet-like structure. The keratin structure is composed of various <a href="https://chem.libretexts.org/Courses/University_of_Kentucky/UK%3A_CHE_103_-_Chemistry_for_Allied_Health_(Soult)/Chapters/Chapter_4%3A_Structure_and_Function/4.4%3A_Functional_Groups">chemical groups</a> (types of atom groupings with similar properties), such as carboxyl groups, amino groups and disulfide groups. Copper ions have the ability to form bonds with these groups, forming a copper-keratin complex. This complex remains in the hair, causing it to appear green. Interestingly, the most recent study <a href="https://doi.org/10.32657/10356/142466">conducted in 2020</a>, showed copper ions mainly bind to the disulfide groups. This study also found other metal ions such as zinc, lead, chromium and mercury also bind to hair in the same way. This is very useful in <a href="https://theconversation.com/forensic-breakthrough-study-suggests-humans-can-be-identified-by-the-proteins-in-their-hair-65051">forensic analysis</a>, for example, because forensic scientists can analyse hair samples to determine if a person has been exposed to a particular metal. Light-coloured hair already has the most visible green discoloration, but research has shown that damaged hair, caused by bleaching, straightening, or exposure to sun, is the <a href="https://pubmed.ncbi.nlm.nih.gov/19586601/">most susceptible</a> to the binding of copper ions. This is because in damaged hair the disulfide groups have “broken bonds” (the link that holds the elements within these groups together is broken), making it easier for the copper ions to bind to the hair. <h2>Can I prevent the green colour or get rid of it?</h2> To prevent your hair from turning green in a swimming pool, you have two basic options. The first is a physical barrier – just wear a swim cap. The second option is chemical – you can pre-treat your hair with an alkaline shampoo. <a href="https://www.sciencedirect.com/science/article/abs/pii/S0891584918310050">Studies have shown</a> under alkaline pH conditions, the copper ions won’t attach to the hair. To treat your hair before going to the pool, you can either use a shampoo with a pH higher than 7, or you can even try mixing some baking soda into your regular shampoo. But what can you do if your hair has already turned greenish? Well, you can try washing your hair with a shampoo designed to achieve this, typically marketed as a “chlorine removal” shampoo. These products contain a chemical called EDTA – it can bind to metal ions (such as copper) and thus will remove copper from the hair. You may have heard tomato sauce or ketchup is a good way to get the green out of your pool hair – potentially because the red pigments are supposed to “cancel out” the green ones. However, I’m not aware of any scientific evidence this would work. Correction: This article has been amended to clarify that alkaline shampoos have a pH higher than 7, not lower.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/211736/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/magdalena-wajrak-1432339">Magdalena Wajrak</a>, Senior lecturer, Chemistry, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

My Royal Melbourne Seniors Classic Adventure: A day on the greens (and in the bunkers!)

G'day to all past, present, and emerging golf enthusiasts! If you're a senior golfer like me, hunting for inspiration, adventure, and authentic golf yarns — this is for you. Picture this: a crisp August morning, and sixty-two senior golfers gathered on Royal Melbourne's West Course for the Vic Seniors Classic 2023. Here's the story of how it all went down... Before anything else, I mustered the guts to jump in. Ever heard of "imposter syndrome"? Trust me, I was its best mate. But the requirements were clear: age 55+ (I'm a proud 65-year-old), GA Handicap under 24.5 (18.5), and a $225 entry fee. Wait, $225? Given that Royal Melbourne's green fees dance around $1000, caddy fee included, it was a no-brainer. Fueled by the temptation of playing a top-notch course for a quarter of the fee, I submitted my application without hesitation. Before I knew it, my name adorned the list of players. As the day approached, I was geared up to tackle the Royal Melbourne challenge. The 8 am shotgun start meant groups teed off from various holes. I found myself at the 11th tee, flanked by two fierce competitors: Peter (Daily Handicap 1) and Damian (12). Yours truly? A modest 20. Standing over the ball, knees a tad wobbly, I swung that driver. The ball sailed gracefully, landing centre fairway, while their shots had taken a wilder route into the rough. The lesson? 'How near,' not 'how far'. Now, let's talk about those Royal Melbourne greens. Rumour had it, they were "super fast". Super fast? Imagine sliding a ball across your kitchen's polished tiles — yep, that rapid. Around the course, bunkers became my stern mentors — big, deep, and oh-so unforgiving. Post 18 holes, scorecards were in, followed by the triumphant crowning of winners over lunch. Rodney Ware (75 gross) and Kevin Naismith (81 gross) led in men's gross, while Wayne Moon (72 net) and Craig Lonsdale (73 net) dominated the net division. Melinda Crawford (16, scratch stableford) and Louise Yuen (29 handicap points) shone in the women's. Kudos to winners, fellow players, Royal Melbourne and Golf Australia for the unforgettable day. By the way, can you see yourself on those hallowed Royal Melbourne greens? If your inner golfer nods, I'm your cheerleader. Consider joining me for the 2024 Royal Melbourne Seniors Classic. And as I wrap up, let me leave you with the timeless words of the legendary Peter Thomson: "Golf is a game of how near, not how far". Until next time, keep those swings buttery, putts steadfast, and steer clear of those tricky bunkers. PS: My result? T43rd (net) among the 48 male players. Next time I'll be swinging even better. About the Writer: Mike Searles is a Melbourne retiree who's living the golfing dream. Image credits: Getty Images

Calories and kilojoules: how do we know the energy content of food, and how accurate are the labels?

<a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>; <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a>, and <a href="https://theconversation.com/profiles/katelyn-barnes-1238606">Katelyn Barnes</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Everything we consume contains energy our bodies use to move, grow and maintain health. To work out how much energy is in different foods and drinks, we need to first look at a few core concepts. Firstly, you’ve probably heard of the units of measurement for energy – calories – as well as the metric equivalent, which is joules. One calorie is defined as the amount of energy required to raise the temperature of 1 gram of water by 1℃. In human nutrition, the amounts of energy needed to maintain health, and to fuel a body, are much larger than the tiny singular calories used to heat up a gram of water. So, the term “calorie” in nutrition commonly refers to a <a href="https://www.sciencedirect.com/science/article/pii/S0022316622085546">kilocalorie</a> (or kcal), which is 1,000 calories. When you see the word “calories” on a nutrition label, it’s likely referring to kcals. The energy stored in food and drinks is released when the body breaks down one or more of the four macronutrients inside the food (carbohydrates, proteins, fats, alcohol). The body then uses that energy for activities such as keeping our heart beating, our lungs breathing and our muscles moving. When energy in food is estimated, it is the amount of energy food and drinks provide for these bodily processes. The four macronutrients provide <a href="https://www.sciencedirect.com/science/article/pii/S0002916522039454">different amounts of energy</a>: <ol> <li>1 gram of carbohydrate provides about 4 kcal of energy</li> <li>1 gram of fat provides about 9 kcal of energy</li> <li>1 gram of protein provides about 4 kcal of energy</li> <li>1 gram of alcohol provides about 7 kcal of energy.</li> </ol> <h2>How are calories estimated?</h2> There are two ways to estimate the amount of energy in food and drinks. The first is called “bomb calorimetry”. This gold-standard method involves placing a small sample of food or drink inside a device known as a bomb calorimeter. The food is burned in the presence of oxygen, releasing heat. The amount of heat released is directly related to the amount of energy in the food, allowing a calculation to be made. This method is most commonly used for foods rich in fats and is considered the most reliable (but expensive) method. The second method, the Atwater system, is a much less expensive method for estimating energy content. It is more commonly used when calculating energy of most food and drinks sold in supermarkets. Named after legendary food researcher <a href="https://www.sciencedirect.com/science/article/pii/S0022316622065336">Wilbur Atwater</a>, this system uses a standard conversion factor for each macronutrient found in food and drinks. By estimating the amount of each of the four macronutrients, an approximate calculation of the total energy can be made. However, this method requires detailed knowledge of the ingredients within composite foods (such as muesli bars or hamburgers) – which may reduce accuracy. There is also a margin of error to expect with the Atwater system, because it assumes each ingredient is always the same in composition. For example, a cup of oats grown in one part of the country won’t necessarily have the exact same nutritional content as another cup of oats grown elsewhere, due to climate and soil differences. So, this system is an estimation based on an average. Importantly, both methods estimate the amount of energy in food and drinks. But the actual energy our bodies extract from these foods and drinks can vary due to factors such as individual differences in digestion and absorption, as well as food processing and cooking methods. <h2>Why do foods have calories written on them?</h2> In Australia, it’s a <a href="https://www.foodstandards.gov.au/consumer/labelling/panels/Pages/default.aspx">legal requirement</a> for packaged food items to have a nutrition information panel that displays the number of kcal it contains. However, homemade food items sold at places like a fresh market may not be required to provide a nutrition information panel. This will depend on the type of food being sold and the scale of the business operation. Fresh foods such as fruit, vegetables and meat also don’t require a nutrition information panel. To find out the number of kcal in them, you can either run an experiment with a bomb calorimeter or look up an estimated value in an online nutrition database. Food composition databases such as <a href="https://www.calorieking.com/us/en/">CalorieKing</a> compile information about the energy and nutrient content of various foods. Dietitians and other health professionals often use these databases to estimate the energy content of foods to inform dietary recommendations. <h2>Different international standards</h2> Both kJ and kcal refer to energy – they are just two different units of measurements (such as how inches and centimetres are two different units for measuring length). Kilojoules (kJ) is part of the International System of Units (SI). Australia, New Zealand and some parts of Europe use kJ. The United States and the United Kingdom use kcal. To convert between calories and kilojoules you use the conversion factors: <ul> <li>1 kcal = 4.184 kJ</li> <li>1 kJ = 0.24 kcal (about ¼).</li> </ul> For example, if you have a packet of chips with an energy content of 200 kcal, you can convert it to kJ as follows: 200 kcal × 4.184 = 836.8 kJ. As for how many calories are acceptable to eat, the Australian Guidelines for Healthy Eating estimate the average adult requires about 7,000kJ or 1,670Kcal every day. However, differences in age, gender, size, health and physical activity will influence how much energy a person needs. To estimate your personal energy requirements, you can use this <a href="https://www.eatforhealth.gov.au/nutrient-reference-values/nutrients-dietary-energy-calculator#results-energy">nutrients and dietary energy calculator</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/211613/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, Professor of Community Health and Wellbeing, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>; <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, Dietitian, Researcher & Lecturer, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a>, and <a href="https://theconversation.com/profiles/katelyn-barnes-1238606">Katelyn Barnes</a>, Postdoctoral Research Fellow, School of Human Movement and Nutrition Sciences, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Mystery object washed up on WA beach finally identified

Ok space enthusiasts and beachcombers. Here's one for the X-Files – Intergalactic Travel edition. Picture this: A strange and baffling object, looking like it's straight out of a sci-fi flick, decided to take a little trip to Green Head beach, about 250 kilometres north of Perth on the pristine WA coastline. As soon as the locals caught sight of this extraterrestrial-looking thingamajig, the news spread like wildfire, and it made international headlines faster than a speeding rocket, with all kinds of fascinating theories popping up as to what on Earth (or not on Earth) it could be. Was it a UFO? A top-secret government experiment gone awry? Well, turns out it was nothing that exciting. The Australian Space Agency put on their Sherlock Holmes hats and deduced that this enigmatic piece of debris probably came from a satellite launch vehicle. Eureka! Case closed! Of course, when something weird and otherworldly shows up on your doorstep, you can't be too careful. So, the local authorities played it safe and put the object under police guard for an entire week. (Better safe than sorry, right?) And who needs a red carpet when you have a front-end loader to transport your newfound cosmic artifact? The experts were summoned to figure out where this space junk came from, and they concluded it was most likely a fuel tank from some rocket launched by the Indian Space Research Organisation. Professor Alice Gorman from Flinders University explained to <a href="https://www.abc.net.au/news/2023-07-31/australian-space-agency-identifies-space-junk-green-head/102669472" target="_blank" rel="noopener">ABC News</a> that this fuel containment vessel was meant to fall off after launch. And it turns out that statistically, we've been pretty lucky not to have had more collisions with falling rocket parts. Imagine explaining that to your insurance company? "A rocket booster landed on my house. Is that covered?" But here comes the tricky part: What to do with all of this space garbage? Should they ship it back to India like some interstellar postcard, or leave it Down Under as an intergalactic souvenir? While India is technically (and legally) responsible for their space debris, they could decide to gift it to Australia if they so choose. It could be like an exotic space decoration for the country - "The Land of Kangaroos and Rocket Wreckage." Even better, the Green Head community itself appear to have come up with a few fabulous ideas. Forget the Sydney Opera House: let's make the space debris a tourist attraction! Move over, Eiffel Tower - we've got our own piece of space history right here. The WA Premier even suggested storing it next to space debris from NASA's Skylab space station (remember that?) in some kind of attempt to build a cosmic cabinet of curiosities. Of course, the local council is also very keen on keeping this celestial treasure. They're hoping the Indian government won't come back to claim it, to the point that everyone in the surrounding Shire of Coorow is buzzing with excitement over the possibility of having their very own space souvenir to draw crowds of star trekkers. And so while the mystery of the object on the beach has been solved, the debate over its fate is just beginning. Will it become a star attraction in a local park? Or will it be shipped off to India like an interplanetary package return? Only time will tell. Images: Nine News

Mysterious liquid turns popular rock pool green

A mysterious liquid has turned a popular public rock pool at Cronulla beach fluorescent green. The liquid, believed to be a natural fluorescent dye, fluorescein, was seen pouring into the usually clear waters of the pool on Friday. The dye is often used to help experts track the flow of water to identify any leaks and has low toxicity, which means it is harmless despite the daunting colour. “We believe the discolouration is likely to be fluorescein dye, which is commonly used in plumbing/drain testing and dissipates quickly once diluted,” a spokesperson for the New South Wales Environmental Protection Authority said. According to Australian dye manufacturer, Tintex, the dye is also used to “locate leaks in plumbing, tracing pipe locations, detect drain damage and water pathways,” and is odourless and non-toxic to the environment. However, in a safety data sheet, Tintex has also warned about the potential health effects which include eye irritation, skin irritation, irritation of the digestive tract and respiratory tract irritation. Many locals are cautious despite the claim that the dye is mostly harmless. One user wrote on a Facebook page for Cronulla locals that dye was “legal to use in a stormwater drain”. “Doesn’t look good whatever it is,” another responded, while other cautious residents replied that they wouldn’t swim in the area until the dye fully dissipates.

Energy bill relief to benefit just one Aussie demographic

Nearly half a million older Australians will receive hundreds of dollars in energy bill relief as the federal government looks to battle rising power prices. Social Services Minister Amanda Rishworth revealed that all Commonwealth seniors health card holders will be given up to $500 per household. The 490,000-plus recipients will include an extra 16,320 people granted access to the card after the federal government introduced higher income thresholds for eligibility in November 2022. The new income limits are $90,000 for singles and $144,000 (combined) for couples. The government claimed this would benefit 52,000 older people by 2026-27. Rishworth explained the energy relief would be available from July 2023. The Australian Energy Regulator (AER) released its final determination on May 25, with a revised price increase higher than the March draft that saw a 20 to 22 per cent rise. AER chair Clare Savage said it had been a “difficult decision” but high wholesale energy costs continued to hike up retail prices. “No one wants to see rising prices, and we recognise this is a difficult time, that’s why it’s important for consumers to shop around for a better deal,” she said. Following the AER’s announcement, Opposition Leader Peter Dutton appeared on Today and said Prime Minister Anthony Albanese had “lied” to Australians about energy prices. “Let’s be very clear about it, he promised on 97 occasions your bill would go down by $275,” he told Today host Karl Stefanovic. “I think the government’s completely underestimating how much families and small businesses are hurting at the moment.” The bill comes shortly after the Australian Energy Regulator revealed electric prices were set to increase by 25 per cent for about 600,000 customers across three states from July 1. The federal government’s latest budget committed to $3 billion in financial support for those struggling to pay their power bill. Image credit: Shutterstock

“She wasn’t ready to die”: Son speaks after mum on life support dies during power outage

A grieving son is calling for energy companies to do better after his mum, Gloria Shae, 80, who was on life support, died during a power outage in Dubbo. Gloria was found collapsed on the floor after her oxygen machine switched off during an unexpected blackout at around 5am on May 8. The great-grandmother was woken up out of a deep sleep and was later on found trying to reach for her bottled oxygen. Now, her son Brian Shae, has spoken up about the tragic incident and is calling for energy companies to do better. "She wasn't ready to die," Brian said. "She was full of life and energy, she had planned what she was doing the next day. He said that his mother was a registered life support customer with Origin Energy and Essential Energy. Neither Brian, who lives in the same property, nor Gloria were notified about the outage by their energy providers. "If there was some sort of automated system that sent out a text message, I could have been there in 30 seconds, in under a minute,” the grieving son said. "We could have assisted her, we could have got her oxygen bottles to her. "She does have oxygen bottles in the home but at night you rely on the oxygen generator." Although emergency services arrived about 15 minutes after Gloria was found, and they managed to restart her heart, Brian said that by then she was already brain dead. Gloria’s oxygen machine was rented and didn't come fitted with a back-up battery. Providers currently only need to give customers using life support four days' notice if there is a planned power outage, but in the case of a blackout there is nothing in place to contact their customers or the next of kin. Instead, they urge vulnerable customers to have a back-up battery or generator, to call triple-zero in an emergency, and to “have contingency plans in place”. “But how could an 80-year-old lady who has woken up out of a deep sleep (and) short of breath manage to go out (and) start a generator?” Brian asked. Health Minister Ryan Park described the death as a “terrible tragedy” and said that he has spoken with NSW Health. The Health Minister also encouraged energy companies to find better ways to support vulnerable customers. “If there’s anything that we could have done differently, we will look at that,” he added. An Essential Energy spokesperson has also commented and said that the team had personally contacted the family to extend their "deepest condolences". Images: 9News

How to make your next holiday better for the environment

<a href="https://theconversation.com/profiles/brendan-canavan-228682">Brendan Canavan</a>, <a href="https://theconversation.com/institutions/university-of-nottingham-1192">University of Nottingham</a> Being an environmentally friendly tourist can be challenging. Tourism is an industry that brings many <a href="https://www.unwto.org/EU-guidebook-on-sustainable-tourism-for-development">negative environmental impacts</a> – our pleasure often comes at the expense of local habitats or wildlife. Maya Bay on Thailand’s uninhabited Phi Phi Leh island became famous as the location of the 2000 Hollywood movie The Beach. But this led to rapid growth in visitors to the bay – as many as 8,000 a day at its peak – and put enormous strain on the bay’s natural habitats. In 2018, the bay was <a href="https://edition.cnn.com/travel/article/maya-bay-thailand-recovery-c2e-spc-intl/index.html">closed to tourists</a> for four years to let its coral reefs and wildlife recover. But tourism can also be an inspiring way to connect with oneself, with others and with new places. As tourists, we can learn, share and contribute to positive environmental practices. As a tourist, you also have influence. The money you spend, the social interactions you have and the resources you consume all <a href="https://www.sciencedirect.com/science/article/abs/pii/S0261517715300224?casa_token=TaXMOLW6Sp4AAAAA:PEnSG1AaAZ-MiuTNZ1wJfLRrzaNVIbaBsk1cKsP8M-_6KjruLO9tp09BqqzGnJTIZbN8_CoP4Q">help to shape an area</a>. So here are four pieces of advice for making your next holiday better for the environment. <h2>Spend locally</h2> We’ve all heard variations on the mantra “<a href="https://cleanisland.org/history-of-the-leave-only-footprints-initiative/#:%7E:text=%E2%80%9CTake%20only%20memories%2C%20leave%20only,the%20Leave%20Only%20Footprints%20program.">take only memories, leave only footprints</a>”. This message of less consumption and lower impact is a good ethos for environmentally sensitive tourism. The first thing to do is think about how you can leave more positive footprints behind. An excellent way to make the most of your economic footprint is to stay and shop in <a href="https://www.tandfonline.com/doi/full/10.1080/09669580802359293?casa_token=eNeLWWRPHxIAAAAA:9bT4S5-0O5b2JQWrYKgmjtDxrZzlv0P-H-9T2SoWT1fX6tFRkoVenNNcfmJbHV9ebhF2kP7XIEgz">independent businesses</a>. These businesses tend to pay local taxes and are owned by and employ local people. More of the money you spend stays in the immediate area as a result. Where tourist money directly benefits local people and businesses, their support for conservation is <a href="https://www.jstor.org/stable/pdf/26069456.pdf?casa_token=rdKkHk5QviUAAAAA:2ZCqsGG1f-2wFTIdmptbrJDVo8iPjYnam7QPdHXviRy_e0wA7YMY7fc0Qm1smIII4cg6_WriJ1OQwPvxMibmeHQxnO81NPd9jwoeVRudUS2TVv2TNeg">often encouraged</a>. Tourists <a href="https://www.sciencedirect.com/science/article/pii/S0261517709000120#sec5">visiting rhino sanctuaries</a> in Botswana, for example, bring income and support jobs. In 2010, the country’s Khama Rhino Sanctuary employed 26 permanent staff and many more casual labourers. This economic security can, in turn, prompt local people to appreciate the importance of protecting vulnerable animal species like rhinos. <a href="https://www.tandfonline.com/doi/abs/10.1080/09669582.2021.1932927?casa_token=rffO3wgsu6UAAAAA:7dounwsgVunXCW4-NERDNDX9Ks_OVfa3z5TfZDojAdiVVKuXbU52_3DnRNfALNjMCW0PzGPPOu0MQQ">Separate research</a> on people living around Kenya’s Maasai Mara nature reserve found that people whose livelihoods were dependent on tourism were more likely to support efforts to conserve local wildlife. <figure class="align-center "><img src="https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="Two white rhinos drinking from a pond." /><figcaption>Two white rhinos at Khama Rhino Sanctuary, Botswana. <a class="source" href="https://www.shutterstock.com/image-photo/white-rhinoceros-ceratotherium-simum-squarelipped-khama-2060738441">Al Carrera/Shutterstock</a></figcaption></figure> <h2>Tread lightly</h2> Tourism creates waste and uses up resources. Treading carefully will minimise the environmental impact you have on your holiday destination. A simple way to lower your environmental footprint is to use fewer resources at every stage of your holiday. A single tourist uses <a href="https://www.e-unwto.org/doi/pdf/10.18111/9789284414529">300 litres</a> of water in their holiday accommodation on average each night. Reusing towels, flushing the toilet less and shortening your shower time can all help to reduce demand for water resources. Thinking about the footprints you leave as a tourist is a useful mindset. You may even become more aware of the positive legacy you can leave behind. Learn about the local area and the environmental issues that matter there. If habitat loss is a problem, contribute to local organisations that support conservation. Organisations like the <a href="https://www.nationaltrust.org.uk/holidays">National Trust</a> even offer holidays in the UK that help to fund their work. <h2>Place matters</h2> Tourism shifts you away from the familiar and gives you <a href="https://www.sciencedirect.com/science/article/abs/pii/S0160738312001211?casa_token=zHTCleS_F3kAAAAA:jWMOOtEJzH8OXySUqafP5Z7koLFOtNSJ2Ik4ncoA9wPCHTW-1MRNJJwRvYtoopoSqCwTRm_TeA">space for self-reflection</a>. Research has found that people have been <a href="https://www.tandfonline.com/doi/abs/10.1080/02508281.2017.1342349?role=button&needAccess=true&journalCode=rtrr20">inspired by travel to make life changes</a> such as relocating or shifting career. Many keen rock climbers, for instance, adopt a <a href="https://www.tandfonline.com/doi/pdf/10.1080/17450101.2014.977667?casa_token=gCsYfe0mSDkAAAAA:q8f6HbQ9rlwXS5_DGl3De1XUnHXX6U0EC3QUNz65pFivUgPo7RDH0-zGXvspjrTrv73FKkouDPM-">minimalist and mobile lifestyle</a>. <a href="https://www.tandfonline.com/doi/full/10.1080/14616688.2012.762691?needAccess=true">One study</a> on climbers’ lifestyles in the US showed that the challenges of life on the road, gatherings at campgrounds and the considerable amount of time spent in nature can be enriching. Rock climbers’ lifestyles are inspired by and connected to natural settings. And many alternative types of tourism are too. These tourists can become powerful advocates for the protection of the places they care deeply about. Surf tourists, for example, have driven <a href="https://www.sas.org.uk/">various campaigns</a> against the discharge of sewage into UK bathing waters. You and those you travel with can be similar cheerleaders for the places you care about. Join organisations fighting for their conservation, contribute to their sustainable development and share your appreciation of these places with others. <h2>Stay curious</h2> A final thing you can do as a tourist is to keep exploring. It can be tempting to stay in a <a href="https://www.jstor.org/stable/pdf/40970087.pdf?casa_token=zGlcyUgr_JcAAAAA:TzIuU8wrbvXyjAxawpea1Nw35y-5DSZX-MShnpndR4iEwzOQqCul3Hn61SFdotC4dO3hMZ6ddpOI-O0v45K7Jwo6TY9I4FVbUaE8QMuGo7qsBFbvbXE">tourist bubble</a> and not leave the confines of your resort or stick with familiar travel groups and activities. Cruises are a classic example of bubble tourism. The places visited do not really matter; the floating hotel is the main attraction. But cruise tourism rarely benefits local populations and brings <a href="https://www.sciencedirect.com/science/article/abs/pii/S0261517717302418?casa_token=dz_gzPmnVTsAAAAA:o6WggzlegsnTGIh9__NvL7POYKzGB3pHd44TNswicbl0sOSc5uTUYG-G_qZroQ3gaQVchZR5Gw">significant negative environmental impacts</a>.

And in urban areas, their activities are likely to take place in a concentrated geographical area. Thinking about the footprints you leave and the memories you take can help you to become a more environmentally aware tourist.

Federal Budget 2023: How to make the most of the key promises

Treasurer Jim Charles has handed down his first budget for 2023/24, offering a series of measures aimed at tackling the cost-of-living crisis. Millions of Australians will receive a boost from the federal government medical care, bills and welfare payments, amid the forecast that the budget will be be in the black with a surplus of $4bn. Here’s what it means for you: Bill help Those who are on the pension, a seniors card holder or a recipient of family tax benefits A and B will be eligible to get help with energy bills thanks to a deal between the states and Commonwealth that’s worth $1.5bn. That means over five million eligible households and one million eligible small businesses will benefit from the scheme. The relief will come in the form of credits that apply directly to their power bills rather than cash, and the amount they receive will depend on the state they live in. Medicare Relief The incentives paid to GPs who bulk bill 11.6m eligible Australians including children under 16, pensioners and other concession card holders will increase. GPs will be able to claim the incentives for in-person consultations over six minutes long and certain telehealth consultations. GPs who bulk bill patients in the city will be paid a new incentive of $20.65 compared to the previous rate of $6.60, while regional GPs will receive a $31.40 incentive, up from $10.05. Welfare recipients Over 1.1 million vulnerable Australians will benefit from a $40 fortnightly boost from September, if parliament agrees. The increased base rate will apply to people receiving JobSeeker, Youth Allowance, Parenting Payment (partnered), ABSTUDY, Disability Support Pension (Youth) and Special Benefit. Rental assistance For many renters, this budget means that rent is forecasted to increase over the next year as the market tightens. However, for those currently receiving the maximum Commonwealth Rent Assistance allowance their payments will increase by 15 per cent. Here’s what the Federal Budget will look like at a glance: <ul> <li dir="ltr"> Budget deficit of $13.9 billion in 2023/24 </li> <li dir="ltr"> Commonwealth net debt to rise to $574.9 billion (22.3 per cent of GDP) in 2023/24 </li> <li dir="ltr"> Economic growth to fall to 1.5 per cent in 2023/24 </li> <li dir="ltr"> Unemployment rate to rise to 4.25 per cent in 2023/24 </li> <li dir="ltr"> Inflation as measured by CPI to be 3.25 per cent in 2023/24 </li> <li dir="ltr"> Wages to rise by four per cent in 2023/24 </li> </ul> And here are the key measures the federal budget has promised: <ul> <li dir="ltr"> Energy bill relief for five million households and one million businesses </li> <li dir="ltr"> Triple bulk-billing incentives and more funding for urgent care clinics </li> <li dir="ltr"> Base rate of JobSeeker and other payments to be raised for 1.1 million households </li> <li dir="ltr"> Commonwealth Rent Assistant rise for 1.1 million households </li> <li dir="ltr"> Housing boost including tax breaks for build-to-rent investors </li> <li dir="ltr"> $4 billion extra for renewable energy </li> <li dir="ltr"> Tax breaks for small business to write-off assets and reduce energy costs </li> <li dir="ltr"> Targeted help for jobless aged over 55 </li> <li dir="ltr"> Cut to cost of medicines </li> </ul> Image: Getty Images/ Martin Ollman / Stringer

1 in 4 households struggle to pay power bills. Here are 5 ways to tackle hidden energy poverty

<a href="https://energyconsumersaustralia.com.au/news/how-increases-in-energy-prices-are-impacting-consumers#:%7E:text=Energy%2520affordability%2520is%2520not%2520just,in%2520the%2520past%252012%2520months.">One in four Australian households</a> are finding it hard to pay their gas and electricity bills. As winter looms, <a href="https://www.aer.gov.au/news-release/default-market-offer-2023%25E2%2580%259324-draft-determination">energy price rises</a> will make it even harder. Cold homes and disconnections resulting from energy poverty threaten people’s health and wellbeing. <a href="https://www.acoss.org.au/wp-content/uploads/2023/03/ACOSS-cost-of-living-report2-March-2023_web_FINAL.pdf">Income support for welfare recipients</a> and retrofitting homes to make them more thermally efficient – by adding insulation, for example – can ease the burden. And when homes are not too cold or hot, <a href="https://theconversation.com/fuel-poverty-makes-you-sick-so-why-has-nothing-changed-since-i-was-a-child-living-in-a-cold-home-201787">people’s health benefits</a>. This in turn <a href="https://apo.org.au/node/319556">eases pressure on the public health system</a>. However, many people are missing out on assistance as programs often do not recognise their difficulties. Their energy vulnerability is hidden. <h2>What forms does hidden energy poverty take?</h2> <a href="https://www.sciencedirect.com/science/article/pii/S2214629623000737">Our newly published study</a> has revealed six aspects of hidden energy vulnerability. These are: <ol> <li> underconsumption – households limit or turn off cooling, heating and/or lights to avoid disconnections </li> <li> incidental masking – other welfare support, such as rent relief, masks difficulties in paying energy bills </li> <li> some households disguise energy poverty by using public facilities such as showers or pooling money for bills between families </li> <li> some people conceal their hardship due to pride or fear of legal consequences, such as losing custody of children if food cannot be refrigerated because the power has been cut off </li> <li> poor understanding of energy efficiency and the health risks of cold or hot homes adds to the problem </li> <li> eligibility criteria for energy assistance programs may exclude some vulnerable households. For example, people with income just above the welfare threshold are missing out on energy concessions. Energy retailer hardship programs also ignore people who have voluntarily disconnected due to financial hardship. </li> </ol> <h2>5 ways to help these households</h2> Our studies suggest trusted intermediaries such as people working in health, energy and social services can play a vital role in identifying and supporting such households. First, energy efficiency and hardship initiatives may be <a href="https://www.rmit.edu.au/about/schools-colleges/property-construction-and-project-management/research/research-centres-and-groups/sustainable-building-innovation-laboratory/projects/care-at-home-system-improvements">integrated into the My Aged Care in-home care system</a>. Energy poverty risk identification, response and referral could be built into the national service’s assessment form. This could leverage existing client screening processes. The system’s front-line staff could connect at-risk householders with energy counsellors. These counsellors could help people access better energy contracts, concessions, home retrofits and appliance upgrade programs. A new Commonwealth “energy supplement” could help pay for essential energy-related home modifications. This would help avoid My Aged Care funds being diverted from immediate healthcare needs. Second, general practitioners and other health professionals could help identify energy vulnerability among patients with medical conditions of concern. They could also provide letters of support emphasising renters’ health-based need for air conditioners or heaters. Third, energy providers could use household energy data to identify those that seem to be under-consuming or are often disconnected. They could also identify those that are not on “best offer” deals. They could be proactive in checking struggling householders’ eligibility for ongoing energy concessions and one-off debt relief grants offered by states and territories. Energy providers could also make it easier for social housing providers to ensure concessions for tenants renew automatically. Fourth, local councils could use their data to identify at-risk householders. They might include those with a disability parking permit, discounted council rates or in arrears, on the social housing waiting list, Meals on Wheels clients and social housing tenants. Maternal and child health nurses and home and community care workers making home visits could call attention to cold or hot homes. Councils could employ in-house energy counsellors to provide assistance and energy literacy training. Council home maintenance teams could develop bulk-buying, insulation and neighbourhood retrofit programs. Strategies to reduce vulnerability to energy poverty should be part of municipal public health and wellbeing plans. Under these strategies, net-zero-carbon funds set up by states and local councils to reduce emissions could finance targeted housing retrofits. We also suggest setting up a central helpline to improve access to energy assistance via local referrals. Fifth, residential energy-efficiency programs could become more person-centric. For example, we already have <a href="https://www.homescorecard.gov.au/">Residential Efficiency Scorecard</a> audits to assess the thermal quality of a home. These audits could also explore whether concessions and better energy deals are available to the household. <h2>Building capacity at all levels</h2> <a href="https://cur.org.au/cms/wp-content/uploads/2021/08/tackling-hidden-energy-final.pdf">Capacity-building strategies</a> are needed at all levels – individual, community and government – to overcome the <a href="https://www.sciencedirect.com/science/article/pii/S2214629623000737">challenges</a> of reducing energy poverty. Current obstacles include the competing priorities of service providers, lack of time and resources, and <a href="https://www.sciencedirect.com/science/article/abs/pii/S2214629622003553">poor co-ordination between siloed</a> programs and services. Access to essential energy services should be part of state and local governments’ strategic health plans. Housing, energy and health departments could work together to include housing retrofits in preventive health programs. A comprehensive approach is needed to overcome hidden energy poverty. It must include public education, integrated services and well-funded energy-efficiency programs. Regulatory reforms and ongoing funding are both needed to improve the availability of energy-efficient, affordable homes for tenants. Our suggested strategies start with improving the skills and knowledge of trusted intermediaries. Doctors, social workers, housing officers, community nurses and volunteers can play a central role. Using these front-line professionals to help identify and act on energy poverty offers a novel, cost-effective and targeted solution.

"Downhearted": Rod Stewart reveals sad reason for cancellation

Fans of Rod Stewart, Cyndi Lauper and Jon Stevens were left devastated after the trio’s highly anticipated performance was cancelled hours before they were due to take the stage. The sad announcement was made just after midday, with the trio set to perform at 4 pm at A Day on the Green festival in Mt Duneed Estate in Geelong, Victoria. Stewart took to Instagram to share his heartfelt apology, “Hello, my friends. I’m absolutely downhearted that I’m disappointing my fans who bought tickets to A Day on the Green. “Late this morning I was advised that I have a viral infection and my throat is too irritated to sing. I’m only human and sometimes get sick just like you do. “My greatest joy is performing for you, so I’m doing everything I can to get on the mend and back on stage!” <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-captioned="" data-instgrm-permalink="https://www.instagram.com/p/Cp7XzziNTVN/?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/p/Cp7XzziNTVN/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Sir Rod Stewart (@sirrodstewart)</a> </div> </blockquote> On Saturday, the promoters of the event posted an online statement confirming that the show was cancelled.

Hundreds of fans have shared their disappointment, with some saying they had travelled just for the show. “Would’ve been good to receive an email/text and not have to find out from a random in a cafe. Booked a weekend away for my mother-in-law’s 60th birthday which is today, we’re beyond devastated,” one person commented in an Instagram post from A Day on the Green. “A text or email would have been lovely, we just arrived after driving 5 hours and our notification was the sign out the front.

Aussies set for power bill relief just before Christmas

The Albanese government has introduced a bill to help battling Aussies feel some relief during the ongoing cost of living crisis by bringing down the cost of unsustainable energy prices. Treasurer Jim Chalmers says Australians need “urgent, targeted, meaningful action” to take some of the sting out of the increasing power costs, which will be addressed through a new energy package to give households and small businesses some relief. MPs and senators were recalled to Canberra for a special session of parliament on Thursday to debate the government’s package, as it will now sail through both houses after Anthony Albanese secured the Senate support of the Greens, David Pocock, and the Jacqui Lambie Network. Opposition Leader Peter Dutton has confirmed the Coalition will not support the Bill, saying it would be “catastrophic” for Australian economic policy. Once passed, gas prices will be capped at $12 a gigajoule for 12 months, which the government says will slash power bills by about $230. The Queensland and NSW governments will also enforce a cap on coal for the same amount of time, at $125 a tonne. The package also includes $1.5 billion of additional relief to small businesses and some households. In introducing the Bill in the House on Thursday morning, Dr Chalmers said without urgent market intervention, retail gas prices were tipped to increase by a further 20 per cent and electricity prices by 36 per cent in the next financial year. “That’s why urgent action is needed … And when we vote today, every member of this place will make a choice,” he said. “To help Australians with rising energy bills – or to make it even harder for them.” “To save Australian jobs – or to surrender them. “ “We choose to protect households and small businesses. We choose to defend our local industries. And we choose to save local jobs.” Image credits: Getty Images

Building and construction emissions and energy use reaches record levels

Despite improvements in energy efficiency, greenhouse pollution levels from the building and construction sector reached an all-time high in 2021. A new report on the building and construction sector by the United Nations Environment Programme released for COP27 found energy demand in buildings – for heating, cooling, lighting and equipment – increased by 4% from 2020 levels. As a result, the sector’s emissions increased 5% compared to 2020. While the increase partly reflects a re-bound in building and construction activities after the pandemic, energy and emissions levels were also above 2019 levels. This is significant because the sector accounts for around a third of total energy demand, the report says. The UN Secretary General Antonio Guterres told the opening forum of COP27 that the future of the planet is in our hands. “…and the clock is ticking. We are in the fight of our lives. And we are losing. Greenhouse gas emissions keep growing. Global temperatures keep rising. And our planet is fast approaching tipping points that will make climate chaos irreversible. “We are on a highway to climate hell with our foot still on the accelerator. “ With the release of the report, UNEP executive director, Inger Andersen added: “If we do not rapidly cut emissions in line with the Paris Agreement, we will be in deeper trouble.” The UNEP report argues investments in energy efficiency must be sustained in the face of growing crises – such as the war in Ukraine and rising energy and living costs – to help with reducing energy demand, avoiding greenhouse gas pollution and reducing energy cost volatility. “The solution may lie in governments directing relief towards low and zero-carbon building investment activities through financial and non-financial incentives,” Andersen says. Also critical to reducing the sector’s emissions are including buildings in climate pledges under the Paris Agreement – known as Nationally Determined Contributions – and mandatory building energy codes. The report’s recommendations include: building coalitions of stakeholders in support of sustainable buildings, governments introducing mandatory building energy codes and government policies, increasing investment in energy efficiency and commitments from industry.  <img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=222598&title=Building+and+construction+emissions+and+energy+use+reaches+record+levels" width="1" height="1" />  <div id="contributors"> <a href="https://cosmosmagazine.com/earth/building-emissions-reach-record-levels/" target="_blank" rel="noopener">This article</a> was originally published on Cosmos Magazine and was written by Petra Stock.

“Hypocrite”: Hughesy's on-air clash with Greens leader

Walking or running: for the same distance, which consumes more energy?
