GLOBAL INDIGENOUS: 'Ring around the' mercury pollution
Deusdedit RuhangariyoICTAround the World: Tree rings show mercury pollution from Peru's illegal mining, Air New Zealand unveils Māori, Pasifika-inspired new uniforms, and access to food in remote communities receives critical boost in Australia
New research has found that certain tropical trees in the Peruvian Amazon can serve as indicators of mercury pollution from gold mining, providing a cost-effective alternative to expensive air monitoring equipment, Mongabay reported on April 8. An estimated 16 million people globally engage in artisanal and small-scale gold mining, much of it illegal and tied to serious environmental and health risks. In regions like the Peruvian Amazon, mercury is commonly used to extract gold from ore. The resulting gold-mercury amalgam is burned, releasing toxic fumes that endanger both miners and surrounding ecosystems.While past studies have largely focused on mercury's impact on aquatic environments where it bioaccumulates in fish and threatens the people who consume them, this new research turns attention to mercury pollution on land.Monitoring airborne mercury on land has traditionally relied on costly equipment, limiting its use in remote or under-resourced areas. To address this, researchers explored an alternative: analyzing tree cores. Like rings in temperate trees, growth rings in certain tropical species can reveal historical exposure to airborne chemicals.'One challenge is that most tropical trees don't form distinct annual rings,' explained Jacqueline Gerson, lead author of the study and an assistant professor at Cornell University. 'But we identified three species known to produce growth rings and sampled them.'Of the three tree types sampled, only the fig tree (Ficus insipida) reliably produced rings. Core samples were collected in 2019 and dated back to 1941, providing nearly 80 years of environmental data.The team collected samples from five locations spaced about 50 kilometers (30 miles) apart, three near active gold mining and two farther away. Four trees were sampled per site, and their mercury content was compared to data from passive air samplers nearby.The results showed a clear link. 'Where you see elevated mercury concentrations in the air, you're seeing elevated concentrations reflected within the tree itself,' Gerson said.Trees located closer to mining sites had higher mercury levels than those farther away. At the most contaminated sites, researchers could track mercury increases over time. At more distant sites, however, changes over time were less apparent.According to Miles Silman, a biology professor at Wake Forest University who was not involved in the research, this breakthrough offers a scalable solution: 'The takeaway is that now we have a way to monitor Hg [mercury] in the air anywhere in the world, making a problem that was difficult and expensive cheap and accessible.'Gerson added that this method could help countries measure their progress under the Minamata Convention on Mercury, a global treaty aimed at reducing human-caused mercury pollution. 'I think it's a really promising tool,' she said.
Air New Zealand has unveiled its new cabin crew attire, assuring the public that the updated designs respectfully celebrate Māori culture without appropriating it, Te Ao Maori News reported on April 10.Created in collaboration with acclaimed Māori tāmoko artist Te Ringatu Netana (Ngāpuhi, Ngāti Wai, Te Arawa) and fashion designer Emilia Wickstead (Nō te Moana nui ā Kiwa), the design partnership produced a uniform that blends Air New Zealand's values with the cultural richness of Aotearoa.Bari Mio, Air New Zealand's Māori development spokesperson who was involved in selecting the designers, emphasized the airline's commitment to avoiding cultural appropriation and to genuinely representing Aotearoa and te iwi Māori through thoughtful and respectful design choices.'It's crucial that we carefully consider how we incorporate Māori elements, including bringing in Māori artists through ethical and respectful processes,' said Mio. He added that Air New Zealand's unique culture helps distinguish Aotearoa globally.Dr. Bobby Luke, a Māori fashion designer and university lecturer, voiced concerns about large companies using Māori imagery and taonga, stressing the need for processes that are 'culturally informed.'Key garments in the collection include:
• The Fine Print – Dress: Features a tūī knot neckline and kōwhai print, inspired by Ngatoro-i-Rangi's story, symbolizing protection, responsibility and belonging.
• The Collective Thread – Shirt: A bold, inclusive design with the tūī knot neckline, wearable by all staff across roles.

Improvements to the Gunbalanya store in Arnhem Land have been announced as part of the federal government's efforts to address food insecurity in remote communities, National Indigenous Times reported on April 11.Earlier this year, the federal government pledged to ensure that 30 essential grocery items in 76 remote community stores across Australia would be sold at city-equivalent prices. As part of that initiative, they also committed to boosting warehouse capacity to stabilize vulnerable supply chains.These efforts are part of a broader 10-year National Strategy aimed at enhancing food security in remote First Nations communities and ensuring consistent access to affordable, nutritious food.On Thursday, the government announced over $341,000 in funding for upgrades at Gunbalanya's Adjumarllarl Store, located 300 kilometres east of Darwin and 60 kilometres northeast of Jabiru. The funds will be used to purchase new refrigeration and freezer units, as well as upgrading the store's point-of-sale system.'This is great news for the residents of Gunbalanya and another example of the Albanese Labor Government investing in remote communities to improve the lives of First Nations people,' said Minister for Indigenous Australians, Malarndirri McCarthy. 'Our investment will strengthen Adjumarllarl Store's capability to supply Gunbalanya residents with nutritious food all year round, including during the wet season.'The upgrade is one of 15 announced through the $9.6 million Store Efficiency and Resilience Package, which was agreed to before the election was called.According to National Indigenous Times, Lingiari MP Marion Scrymgour, who is defending her seat, welcomed the investment: 'Every person across the country deserves access to nutritious and healthy food all year round. This investment for the people of Gunbalanya will enable Adjumarllarl Store to provide this need to the community.''While the opposition has criticized the government's approach to tackling food insecurity, Indigenous Affairs spokesperson Jacinta Nampijinpa Price argued that 'the government can't continue to subsidize their way out of the cost-of-living crisis.' However, critics have also noted a lack of concrete policy proposals from the coalition in support of Indigenous communities.In response, McCarthy emphasized the importance of bipartisan support and the broader purpose of the funding: 'This package is not just building resilience, it's an investment in the health and wellbeing of First Nations people, and part of our broader commitment to Closing the Gap.'Other stores receiving similar support include Maningrida, Kalkarindji, Timber Creek, Lajamanu, and several stores across Queensland, South Australia, and the Northern Territory.
My final thoughts are in Peru where the use of mercury in illegal gold mining is a serious threat to both people and the planet. In places like the Peruvian Amazon, miners, often driven by poverty, are exposed daily to toxic fumes as they burn mercury to extract gold.It's a silent crisis that's poisoning communities and damaging ecosystems with little oversight or accountability.Mercury doesn't just vanish. Once released, it settles into the land and water, entering the food chain and putting entire communities at risk. It causes long-term health issues, especially for children, and its effects can last for generations. What's worse, most of the focus has been on water pollution, while mercury in the air, right where people live and work, has been harder to track.That's why this new research is so important. By using tropical trees like the fig tree (Ficus insipida), scientists have found a cheaper, natural way to detect mercury pollution over time. Tree rings are acting like environmental time machines, revealing decades of contamination in areas close to mining.The way forward is clear. We need stronger enforcement against illegal mining and real investment in safer, sustainable alternatives.Local communities must be equipped with affordable tools, like tree core monitoring to track pollution and demand accountability. This is about justice, health and protecting the future.

Researchers raise alarm after disturbing behavioral shift among Amazon birds: 'It's very sad'
Recent research is indicating that a mere 1° C (or 1.8° F) increase in average dry season temperatures locally could mean a 63% drop in some Amazonian bird populations, according to a mid-May report from Mongabay. The study, published in the journal Science Advances in January, examined 27 years of data for the populations of 29 Amazon bird species. In that timeframe, 24 of the species showed reductions in population size. Researchers suggest that shrinking insect populations — potentially a result of higher temperatures — mean less food for birds. The heat itself may also act as a direct stressor for the animals. While some might expect seemingly tucked-away portions of the Amazon to be sheltered from the worst of the climate crisis, this study is showing that its effects are reaching even the most remote areas of the planet. "These birds obviously experienced temperature changes of 1° C (1.8° F) or 2° C (3.6 °F) over these millions of years, but they occurred slowly over time, allowing the species time to adapt," study co-author Jared Wolfe told Mongabay. "Right now, we are talking about rapid changes over 10 or 20 years, and these birds don't have the [ability] to keep up with them. And it's very sad," he said. The Amazon rainforest is a hotbed for biodiversity, home to many species that science has yet to fully understand. The delicate balance between the species there provides ecosystem services not only to the region, but the world. Hits to local bird and insect numbers are likely to have a range of ripple effects. But they may also serve as indicators of disasters yet to come, being perhaps simply a more tropical canary in the coal mine. The co-authors highlight in their paper the importance of learning more about conditions that could be protective of vulnerable species. "Identifying the landscape characteristics that confer resilience to tropical forests and formulating policies to safeguard these resilient forests are essential steps toward ensuring the persistence of vulnerable tropical bird communities into the 22nd century," they write. Researchers intend to follow up with a study that zeroes in on isolated bird populations and another observing the effects of irrigation on populations during the dry season. The results could inform best practices for sustaining bird populations and potentially other life forms as global temperatures rise due to human-caused pollution. Still, this study delivers a strong message on its own. "This article unequivocally links climate changes with the birds' survival," Wolfe told Mongabay. "It was just a hypothesis until now, but this analysis confirms that they are playing a significant role in bird deaths in central Amazonia." Do you worry about air pollution in and around your home?

New study raises concerns over troubling phenomenon pushing amphibian species to their limits: 'Will likely exceed our projections'
Planet-warming pollution isn't a future threat to amphibians — it's a problem impacting their survival right now. A recent study published in Nature found that the planet has already heated so much that around 2% of amphibian species are already subject to overheating events in their native homes. If warming remains unchecked, researchers say that number could rise to 7.5% of species pushed past their heat-tolerance limits by the end of the century. As detailed in the study, amphibians — including frogs and salamanders — rely on their environment to regulate their body temperature. If it gets too hot, they experience impacts or simply can't survive — as Mongabay summarized. Heat-trapping pollution has already made the globe unbearable for some species. "We found that currently, about 100 species [104 out of 5,203 studied] are likely experiencing overheating events right now, where environmental temperatures exceed their physiological heat limits," study co-author Alex Gunderson, an ecologist at Tulane University, told Mongabay. To evaluate the climate's impact on amphibians, the researchers used experiment-based heat tolerance data for 524 species and statistical estimates for more than 5,000 species. Altogether, their research covered about 60% of all known amphibian species. They pinpointed global "hotspots" where many amphibians are already overheating, including the southeastern U.S., northern Australia, and the Amazon Rainforest, as Mongabay detailed. However, it's not just geography that matters. Where an amphibian lives within its habitat also plays a role. The study found that aquatic species are generally safest from the effects of planet-warming pollution, while ground-dwelling species face the highest risk of overheating. The study also identified a dangerous tipping point for amphibians — between 2 and 4 degrees Celsius (3.6 to 7.2 degrees Fahrenheit) of planetary warming over preindustrial levels. Gunderson told Mongabay that as the average temperature gets closer to that range, the number of days with heat beyond what amphibians can handle starts to significantly climb. Alarmingly, the United Nations Environment Programme estimated in late 2023 that the planet was on track for about 2.5 to 2.9 degrees Celsius of warming by 2100 without additional reductions in planet-warming pollution. The researchers indicated to Mongabay that their estimates are on the conservative side since they assumed all amphibians can find shade. "Therefore, the impacts of global warming will likely exceed our projections," lead author Patrice Pottier, a researcher at the University of New South Wales, told the news outlet. Amphibians are an essential part of their ecosystems, so any threat to their well-being has the potential to disrupt an area's entire food web — as well as have impacts on humans. Do you think America has a plastic waste problem? Definitely Only in some areas Not really I'm not sure Click your choice to see results and speak your mind. A decline in amphibian populations can have negative human health impacts. Amphibians eat insects that transmit diseases, including mosquitoes. Mongabay cited a 2020 study that showed that the decline of amphibian species in Central America was linked to an increase in malaria. Amphibians help control insect populations in their ecosystems, cycle nutrients, and serve as food for many other species. Their decline is a direct trigger for broader environmental consequences. "They're sort of the potato chips of the forest in many of these ecosystems where they serve as food for birds and bats and mammals and fish," Gunderson told Mongabay. One scientist unaffiliated with the study told Mongabay that research of this kind is often used to help decide where to focus conservation work by identifying at-risk species and triaging where the greatest impact can be made. In the study, the researchers called for increased conservation efforts to protect amphibian habitats worldwide, especially focused on maintaining dense vegetation for shade and abundant water for hydration. "If you provide amphibians with enough water and enough shade, a lot of them can survive extreme heat events," Pottier told Mongabay. "We must protect and restore the environments that allow them to regulate their body temperature." Along with conservation efforts, scientists are employing captive breeding and, in some cases, assisted migration to help vulnerable species survive. In the end, however, none of that will be enough without bigger action to address the root cause — pollution itself.
