How changes in California culture have influenced the evolution of wild animals in Los Angeles

A new study argues that religion, politics and war affect how animals and plants in cities evolve, and the confluence of these forces seem to be actively affecting urban wildlife in L.A.

For decades, biologists have studied how cities affect wildlife by altering food supplies, fragmenting habitats and polluting the environment. But a new global study argues that these physical factors are only part of the story. Societal factors, the researchers claim, especially those tied to religion, politics and war, also leave lasting marks on the evolutionary paths of the animals and plants that share our cities.Published in Nature Cities, the comprehensive review synthesizes evidence from cities worldwide, revealing how human conflict and cultural practices affect wildlife genetics, behavior and survival in urban environments.The paper challenges the tendency to treat the social world as separate from ecological processes. Instead, the study argues, we should consider the ways the aftershocks of religious traditions, political systems and armed conflicts can influence the genetic structure of urban wildlife populations. (Gabriella Angotti-Jones / Los Angeles Times) “Social sciences have been very far removed from life sciences for a very long time, and they haven’t been integrated,” said Elizabeth Carlen, a biologist at Washington University in St. Louis and co-lead author of the study. “We started just kind of playing around with what social and cultural processes haven’t been talked about,” eventually focusing on religion, politics and war because of their persistent yet underexamined impacts on evolutionary biology, particularly in cities, where cultural values and built environments are densely concentrated.Carlen’s own work in St. Louis examines how racial segregation and urban design, often influenced by policing strategies, affect ecological conditions and wild animals’ access to green spaces.“Crime prevention through environmental design,” she said, is one example of how these factors influence urban wildlife. “Law enforcement can request that there not be bushes … or short trees, because then they don’t have a sight line across the park.” Although that design choice may serve surveillance goals, it also limits the ability of small animals to navigate those spaces.These patterns, she emphasized, aren’t unique to St. Louis. “I’m positive that it’s happening in Los Angeles. Parks in Beverly Hills are going to look very different than parks in Compton. And part of that is based on what policing looks like in those different places.” This may very well be the case, as there is a significantly lower level of urban tree species richness in areas like Compton than in areas like Beverly Hills, according to UCLA’s Biodiversity Atlas. A coyote wanders onto the fairway, with the sprinklers turned on, as a golfer makes his way back to his cart after hitting a shot on the 16th hole of the Harding golf course at Griffith Park. (Mel Melcon / Los Angeles Times) The study also examines war and its disruptions, which can have unpredictable effects on animal populations. Human evacuation from war zones can open urban habitats to wildlife, while the destruction of green spaces or contamination of soil and water can fragment ecosystems and reduce genetic diversity.In Kharkiv, Ukraine, for example, human displacement during the Russian invasion led to the return of wild boars and deer to urban parks, according to the study. In contrast, sparrows, which depend on human food waste, nearly vanished from high-rise areas.All of this, the researchers argue, underscores the need to rethink how cities are designed and managed by recognizing how religion, politics and war shape not just human communities but also the evolutionary trajectories of urban wildlife. By integrating ecological and social considerations into urban development, planners and scientists can help create cities that are more livable for people while also supporting the long-term genetic diversity and adaptability of the other species that inhabit them.This intersection of culture and biology may be playing out in cities across the globe, including Los Angeles.A study released earlier this year tracking coyotes across L.A. County found that the animals were more likely to avoid wealthier neighborhoods, not because of a lack of access or food scarcity, but possibly due to more aggressive human behavior toward them and higher rates of “removal” — including trapping and releasing elsewhere, and in some rare cases, killing them. In lower-income areas, where trapping is less common, coyotes tended to roam more freely, even though these neighborhoods often had more pollution and fewer resources that would typically support wild canines. Researchers say these patterns reflect how broader urban inequities are written directly into the movements of and risks faced by wildlife in the city.Black bears, parrots and even peacocks tell a similar story in Los Angeles. Wilson Sherman, a PhD student at UCLA who is studying human-black bear interactions, highlights how local politics and fragmented municipal governance shape not only how animals are managed but also where they appear. (Carolyn Cole / Los Angeles Times) “Sierra Madre has an ordinance requiring everyone to have bear-resistant trash cans,” Sherman noted. “Neighboring Arcadia doesn’t.” This kind of patchwork governance, Sherman said, can influence where wild animals ultimately spend their time, creating a mosaic of risk and opportunity for species whose ranges extend across multiple jurisdictions.Cultural values also play a role. Thriving populations of non-native birds, such as Amazon parrots and peacocks, illustrate how aesthetic preferences and everyday choices can significantly influence the city’s ecological makeup in lasting ways.Sherman also pointed to subtler, often overlooked influences, such as policing and surveillance infrastructure. Ideally, the California Department of Fish and Wildlife would be the first agency to respond in a “wildlife situation,” as Sherman put it. But, he said, what often ends up happening is that people default to calling the police, especially when the circumstances involve animals that some urban-dwelling humans may find threatening, like bears.Police departments typically do not possess the same expertise and ability as CDFW to manage and then relocate bears. If a bear poses a threat to human life, police policy is to kill the bear. However, protocols for responding to wildlife conflicts that are not life-threatening can vary from one community to another. And how police use non-lethal methods of deterrence — such as rubber bullets and loud noises — can shape bear behavior.Meanwhile, the growing prevalence of security cameras and motion-triggered alerts has provided residents with new forms of visibility into urban biodiversity. “That might mean that people are suddenly aware that a coyote is using their yard,” Sherman said. In turn, that could trigger a homeowner to purposefully rework the landscape of their property so as to discourage coyotes from using it. Surveillance systems, he said, are quietly reshaping both public perception and policy around who belongs in the city, and who doesn’t. A mountain lion sits in a tree after being tranquilized along San Vicente Boulevard in Brentwood on Oct. 27, 2022. (Wally Skalij / Los Angeles Times) Korinna Domingo, founder and director of the Cougar Conservancy, emphasized how cougar behavior in Los Angeles is similarly shaped by decades of urban development, fragmented landscapes and the social and political choices that structure them. “Policies like freeway construction, zoning and even how communities have been historically policed or funded can affect where and how cougars move throughout L.A.,” she said. For example, these forces have prompted cougars to adapt by becoming more nocturnal, using culverts or taking riskier crossings across fragmented landscapes.Urban planning and evolutionary consequences are deeply intertwined, Domingo says. For example, mountain lion populations in the Santa Monica and Santa Ana mountains have shown signs of reduced genetic diversity due to inbreeding, an issue created not by natural processes, but by political and planning decisions — such as freeway construction and zoning decisions— that restricted their movement decades ago.Today, the Wallis Annenberg Wildlife Crossing, is an attempt to rectify that. The massive infrastructure project is happening only, Domingo said, “because of community, scientific and political will all being aligned.”However, infrastructure alone isn’t enough. “You can have habitat connectivity all you want,” she said, but you also have to think about social tolerance. Urban planning that allows for animal movement also increases the likelihood of contact with people, pets and livestock — which means humans need to learn how to interact with wild animals in a healthier way.In L.A., coexistence strategies can look very different depending on the resources, ordinances and attitudes of each community. Although wealthier residents may have the means to build predator-proof enclosures, others lack the financial or institutional support to do the same. And some with the means simply choose not to, instead demanding lethal removal., “Wildlife management is not just about biology,” Domingo said. “It’s about values, power, and really, who’s at the table.”Wildlife management in the United States has long been informed by dominant cultural and religious worldviews, particularly those grounded in notions of human exceptionalism and control over nature. Carlen, Sherman and Domingo all brought up how these values shaped early policies that framed predators as threats to be removed rather than species to be understood or respected. In California, this worldview contributed not only to the widespread killing of wolves, bears and cougars but also to the displacement of American Indian communities whose land-based practices and beliefs conflicted with these approaches. A male peacock makes its way past Ian Choi, 21 months old, standing in front of his home on Altura Road in Arcadia. (Mel Melcon / Los Angeles Times) Wildlife management in California, specifically, has long been shaped by these same forces of violence, originating in bounty campaigns not just against predators like cougars and wolves but also against American Indian peoples. These intertwined legacies of removal, extermination and land seizure continue to influence how certain animals and communities are perceived and treated today.For Alan Salazar, a tribal elder with the Fernandeño Tataviam Band of Mission Indians, those legacies run deep. “What happened to native peoples happened to our large predators in California,” he said. “Happened to our plant relatives.” Reflecting on the genocide of Indigenous Californians and the coordinated extermination of grizzly bears, wolves and mountain lions, Salazar sees a clear parallel.“There were three parts to our world — the humans, the animals and the plants,” he explained. “We were all connected. We respected all of them.” Salazar explains that his people’s relationship with the land, animals and plants is itself a form of religion, one grounded in ceremony, reciprocity and deep respect. Salazar said his ancestors lived in harmony with mountain lions for over 10,000 years, not by eliminating them but by learning from them. Other predators — cougars, bears, coyotes and wolves — were also considered teachers, honored through ceremony and studied for their power and intelligence. “Maybe we had a better plan on how to live with mountain lions, wolves and bears,” he said. “Maybe you should look at tribal knowledge.”He views the Wallis Annenberg Wildlife Crossing — for which he is a Native American consultant — as a cultural opportunity. “It’s not just for mountain lions,” he said. “It’s for all animals. And that’s why I wanted to be involved.” He believes the project has already helped raise awareness and shift perceptions about coexistence and planning, and hopes that it will help native plants, animals and peoples.As L.A. continues to grapple with the future of wildlife in its neighborhoods, canyons and corridors, Salazar and others argue that it is an opportunity to rethink the cultural frameworks, governance systems and historical injustices that have long shaped human-animal relations in the city. Whether through policy reform, neighborhood education or sacred ceremony, residents need reminders that evolutionary futures are being shaped not only in forests and preserves but right here, across freeways, backyards and local council meetings.

Chun / Los Angeles Times) The research makes clear that wildlife is not simply adapting to urban environments in isolation; it is adapting to a range of factors, including policing, architecture and neighborhood design. Carlen believes this opens a crucial frontier for interdisciplinary research, especially in cities like Los Angeles, where uneven geographies, biodiversity and political decisions intersect daily. “I think there’s a lot of injustice in cities that are happening to both humans and wildlife,” she said. “And I think the potential is out there for justice to be brought to both of those things.”

Drought is draining water supplies and driving up food costs where you’d least expect

From Mexico City to the Mekong Delta, increasingly severe droughts caused by climate change are laying waste to ecosystems and economies everywhere.

Taking shovels and buckets to a dried-up sandy belt of the Vhombozi River in Zimbabwe last August, groups of Mudzi district villagers gathered to dig with the hope of somehow finding water. The southern African region had entered into a state of severe drought, which had shriveled the Vhombozi, a primary water supply for more than 100,000 people. Before long, a maze of makeshift holes revealed shallow puddles along the otherwise arid riverbed. The frantic digging had worked — there was water. There was just one big problem: It wasn’t blue. It was a muddy brown color, and villagers worried that consuming it would make them ill. But as there were scarcely other options, many took their chances with drinking it and bathing with it.  Almost a year later, the persistent drought has led to a deluge of devastation on the region’s food system. Corn yields dropped 70 percent across the country, causing consumer prices to double. Thousands of cattle were lost to thirst and starvation. A local UNICEF emergency food distribution lost all of the food crops it harvested, which forced the NGO to reduce charitable food provisions from three meals a week to one. Child malnutrition levels in Mudzi doubled, driving up the demand for health care, and causing a quarter of health care clinics to run out of water reserves. Between January and March, about 6 million people in Zimbabwe faced food insecurity. According to a new report by the U.S. National Drought Mitigation Center, or NDMC, and the U.N. Convention to Combat Desertification, or UNCCD, the combined effects of global warming, drought, and El Niño have triggered similar crises all over the world, from Mexico City to the Mekong Delta. Using impact reports alongside government data, scientific and technical research, and media coverage of major drought events, the authors examined case-by-case how droughts compound poverty, hunger, energy insecurity, and ecosystem collapse in climate hot spots around the world. They measured impacts in 2023 and 2024, when the planet saw some of the most widespread and damaging drought events in recorded history. What they found is a lesson and a warning sign: Increasingly severe droughts caused by climate change are laying waste to ecosystems and economies everywhere.  “This report is a blistering reminder that climate change and punishing drought are already devastating lives, livelihoods, and food access,” said Million Belay of the International Panel of Experts on Sustainable Food Systems, and general coordinator of the Alliance for Food Sovereignty in Africa, who wasn’t involved in the research. “We need to get serious about resilience and real adaptation.” A local farmer carries vegetables near a partially dry canal of a Chinampa, or floating garden, in San Gregorio Atlapulco, on the outskirts of Mexico City, Mexico, on May 23, 2024. Daniel Cardenas / Anadolu via Getty Images Mexico City A focal point in the analysis is Mexico, where prolonged drought conditions provoked a water crisis that has had repercussions for food affordability and access.  The situation began to intensify in 2023, when the country entered into a period of historically low rainfall. By June, the bulk of Mexico’s reservoirs dropped below 50 percent capacity. The rainy winter of 2023 brought some relief, but not enough.  By the next summer, 90 percent of the country was experiencing some level of drought, and Mexico City’s water supply system reached a record low of 39 percent capacity. Abnormally low rainfall and high temperatures, made worse by inefficient water infrastructure and overextraction of the city’s aquifer, would persist into early 2025. These struggles to obtain water have been further exacerbated by distribution needs as mandated by a water-sharing treaty Mexico has long shared with the United States.  A severe lack of water has been found to be closely linked with food insecurity, as water scarcity impacts food access through reductions in agricultural production that can fuel food shortages and higher grocery prices. Roughly 42 percent of Mexico’s population was food-insecure in 2021, according to national statistics, with consumer food inflation rates steadily climbing since then. Price hikes were eventually reflected in grocery stores, causing the costs of produce like cilantro to soar by 400 percent, alongside other climbing price tags for goods like onions, broccoli, and avocados.  “Ripple effects can turn regional droughts into global economic shocks,” said NDMC’s Cody Knutson, who co-authored the report. “No country is immune when critical water-dependent systems start to collapse.”  Locals carry banana produce over the dry Solimoes riverbed in the Pesqueiro community in Northern Brazil, on September 30, 2024. Michael Dantas / AFP via Getty Images Amazon Basin During those same years, the Amazon River Basin became another drought and hunger hot spot. According to the new report, climate change caused waterways to drop to historically low levels in September of 2023. Drinking water became contaminated by mass die-offs of marine life, and local communities weren’t able to eat the fish they rely on.  Supply chain transportation was also greatly affected, as the low water levels made it impossible for boats to travel in and out of certain regions. Brazil’s AirForce would be deployed to distribute food and water to several states where river supply routes were impassable.  Residents in some towns dug wells on their own properties to replace river water they would normally depend on for drinking, cooking, and cleaning, according to the U.N.-backed report. Others were stuck waiting on government aid. Disruptions to drinking water and food supplies due to low river levels continued through late 2024 as the drought persisted. By September, waterways that had previously been navigable were bone-dry.  A 2025 report released by the nonprofit ACAPS found that many communities in the Amazon region were already believed to be suffering malnutrition, making them more vulnerable to the emerging health and food insecurity effects of the drought.  Climate change plays “a critical role in food security,” said FAO economist Jung-eun Sohn, who is unaffiliated with the UNCCD report. He noted that warming not only can impact both availability of and access to food, but that natural hazards are “one of three main risks of food insecurity,” along with conflict and economic risks, in hunger hot spots.  A woman stands in a dried-out banana plantation in Ben Tre Province, Vietnam, in 2016. At the time, Vietnam’s Mekong Delta was experiencing its worst drought in 90 years. Christian Berg / Getty Images Mekong Delta  Though a central contributor to the interconnected water-and-food crisis, climate change isn’t the only factor in many hunger hot spots — failing infrastructure and inefficiencies in water delivery systems have also been flagged as critical contributors to widespread water shortages. The compounding effect of El Niño, or a naturally-occurring weather phenomena that drives above-average global heat and more intense natural disasters in parts of the planet, is another culprit.  “It’s now abundantly clear that industrial, chemical-intensive agriculture, with its high water demands and uniform crops, is deeply vulnerable to drought and intensifying the crisis,” said Belay, the IPES expert.  One study found that saltwater intrusion, much like what persistently plagues the Mekong River Delta in Vietnam, also causes a significant reduction in food production. The watershed flows through six Asian countries, and over 20 million people depend on the rice grown in the region, which is Vietnam’s most productive agricultural area. It is also the region of Vietnam that is most vulnerable to hunger, with up to half of its rural households struggling to afford enough food.  A woman looks over her spoiled watermelon field in Ben Tre Province, Vietnam, in 2016. At the time, Vietnam’s Mekong Delta was experiencing its worst drought in 90 years. Christian Berg / Getty Images So when an early heat wave struck the Mekong Delta in 2024, and an abnormally long dry spell followed suit, causing canals to dry up, excessive salinity, heat, and water scarcity killed farmers’ catch in droves, reducing what communities were able to supply and sell, which led to shortages that prompted the local government to intervene and help producers quickly sell their wares. As the drought persisted, communities undertook other desperate measures to mitigate losses; renovating ditches, constructing temporary reservoirs, digging wells, and storing fresh water. Even so, according to the report, up to 110,000 hectares of agricultural resources, including fruit crops, rice fields, and aquaculture, have been impacted in the last year by the drought and excess salinity. The situation contributed to rice shortages, prompting a widespread inflationary effect on market prices. “These instances highlight how interconnected our global economies and food supplies are,” Paula Guastello, NDMC drought impacts researcher and lead author of the report, told Grist. “Drought has widespread implications, especially when it occurs on such a large, intense scale as during the past few years. In today’s global society, it is impossible to ignore the effects of drought occurring in far-off lands.”  All told, the authors argue that without major reductions in greenhouse gas emissions, rising temperatures will lead to more frequent and severe droughts by continuing to inflate heat, evaporation, and volatile precipitation patterns. All the while, urbanization, land use changes, and population growth are expected to continue to strain water resources and influence which assets and areas are most vulnerable to drought impacts. The world’s resilience to those impacts, the report denotes, ultimately depends on the fortification of ecosystems, the adoption of changes to water management, and the pursuit of equitable resource access.  “Proactive drought management is a matter of climate justice, equitable development, and good governance,” said UNCCD Deputy Executive Secretary Andrea Meza in a statement about the report. Stronger early warning systems and real-time drought impact monitoring, for example, those that assess conditions known to fuel food and water insecurity, are some of the ways countries can better fortify their systems in preparedness for the next big drought event. Others include watershed restoration, the broad revival of traditional cultivation practices, and the implementation of alternative water supply technologies to help make infrastructure more climate-resilient. Adaptation methods, however, must also account for the most vulnerable populations, the authors say, and require global cooperation, particularly along critical food trade routes.  “Drought is not just a weather event,” said report co-author and NDMC assistant director Kelly Helm Smith. “It can be a social, economic, and environmental emergency. The question is not whether this will happen again, but whether we will be better prepared next time.” This story was originally published by Grist with the headline Drought is draining water supplies and driving up food costs where you’d least expect on Jul 9, 2025.

Something Strange Is Happening to Tomatoes Growing on the Galápagos Islands

Scientists say wild tomato plants on the archipelago's western islands are experiencing "reverse evolution" and reverting back to ancestral traits

Something Strange Is Happening to Tomatoes Growing on the Galápagos Islands Scientists say wild tomato plants on the archipelago’s western islands are experiencing “reverse evolution” and reverting back to ancestral traits Sarah Kuta - Daily Correspondent July 9, 2025 4:29 p.m. Scientists are investigating the production of ancestral alkaloids by tomatoes in the Galápagos Islands. Adam Jozwiak / University of California, Riverside Some tomatoes growing on the Galápagos Islands appear to be going back in time by producing the same toxins their ancestors did millions of years ago. Scientists describe this development—a controversial process known as “reverse evolution”—in a June 18 paper published in the journal Nature Communications. Tomatoes are nightshades, a group of plants that also includes eggplants, potatoes and peppers. Nightshades, also known as Solanaceae, produce bitter compounds called alkaloids, which help fend off hungry bugs, animals and fungi. When plants produce alkaloids in high concentrations, they can sicken the humans who eat them. To better understand alkaloid synthesis, researchers traveled to the Galápagos Islands, the volcanic chain roughly 600 miles off the coast of mainland Ecuador made famous by British naturalist Charles Darwin. They gathered and studied more than 30 wild tomato plants growing in different places on various islands. The Galápagos tomatoes are the descendents of plants from South America that were probably carried to the archipelago by birds. The team’s analyses revealed that the tomatoes growing on the eastern islands were behaving as expected, by producing alkaloids that are similar to those found in modern, cultivated varieties. But those growing on the western islands, they found, were creating alkaloids that were more closely related to those produced by eggplants millions of years ago. Tomatoes growing on the western islands (shown here) are producing ancestral alkaloids.  Adam Jozwiak / University of California, Riverside Researchers suspect the environment may be responsible for the plants’ unexpected return to ancestral alkaloids. The western islands are much younger than the eastern islands, so the soil is less developed and the landscape is more barren. To survive in these harsh conditions, perhaps it was advantageous for the tomato plants to revert back to older alkaloids, the researchers posit. “The plants may be responding to an environment that more closely resembles what their ancestors faced,” says lead author Adam Jozwiak, a biochemist at the University of California, Riverside, to BBC Wildlife’s Beki Hooper. However, for now, this is just a theory. Scientists say they need to conduct more research to understand why tomato plants on the western islands have adapted this way. Scientists were able to uncover the underlying molecular mechanisms at play: Four amino acids in a single enzyme appear to be responsible for the reversion back to the ancestral alkaloids, they found. They also used evolutionary modeling to confirm the direction of the adaptation—that is, that the tomatoes on the western islands had indeed returned to an earlier, ancestral state. Among evolutionary biologists, “reverse evolution” is somewhat contentious. The commonly held belief is that evolution marches forward, not backward. It’s also difficult to prove an organism has reverted back to an older trait through the same genetic pathways. But, with the new study, researchers say they’ve done exactly that. “Some people don’t believe in this,” says Jozwiak in a statement. “But the genetic and chemical evidence points to a return to an ancestral state. The mechanism is there. It happened.” So, if “reverse evolution” happened in wild tomatoes, could something similar happen in humans? In theory, yes, but it would take a long time, Jozwiak says. “If environmental conditions shifted dramatically over long timescales, it’s possible that traits from our distant past could re-emerge, but whether that ever happens is highly uncertain,” Jozwiak tells Newsweek’s Daniella Gray. “It’s speculative and would take millions of years, if at all.” Get the latest stories in your inbox every weekday.

Thirsty future: Australia’s green hydrogen targets could require vastly more water than the government hopes

To make green hydrogen, take water and split it into hydrogen and oxygen. It sounds simple – but the government’s water-use figures may be a drastic underestimate.

totajla/ShutterstockGreen hydrogen is touted by some as the future – a way for Australia to slowly replace its reliance on fossil fuel exports. The energy-dense gas has the potential to reduce emissions in sectors challenging to decarbonise, such as steelmaking and fertiliser manufacturing. The Albanese government wants it to be a massive new export industry and has laid out a pathway through its National Hydrogen Strategy. Unfortunately, there’s a real gap between rhetoric and reality. Despite ambitious plans, no green hydrogen project has yet succeeded in Australia. The technology’s most prominent local backer, billionaire miner Twiggy Forrest, has dialled down his ambition. Globally, just 7% of announced green hydrogen projects are up and running. Economic viability is one problem. But there’s a much larger issue flying under the radar: water. Hitting the 2050 target of 15 million to 30 million tonnes of hydrogen a year would use 7–15% of the amount Australia’s households, farms, mines and black coal power plants use annually. That’s simply not sustainable. Splitting water Green hydrogen uses renewable energy to power electrolyser machines, which split water molecules into hydrogen and oxygen. On the surface, this is an appealing use of clean energy, especially during solar peak periods. But what the government hasn’t properly accounted for is the water cost for green hydrogen. The strategy states water use is likely to be “considerable but not prohibitive”. This is questionable. For every kilogram of hydrogen produced through electrolysis, nine litres of water are directly consumed. That’s not all. The water needed to make hydrogen has to be extremely pure. Salt water has to be desalinated, and even fresh water needs purification. Equipment also needs cooling, which consumes even more water. All these processes incur substantial indirect water losses, such as the water used for industrial processes and cooling. The volumes used are highly uncertain. They can be up to 20 times greater than the direct water use. A key input value for the government’s hydrogen strategy modelling is taken from a 2015 report by the Argonne National Energy Laboratory in the United States, which assumes each kilogram of green hydrogen produced requires just over 30 litres of water. The Australian hydrogen strategy suggests 30 litres per kilogram of hydrogen would cover “all system losses including purification processes and cooling water required”. But it’s not clear if this figure covers other uses of water in making hydrogen, such as water treatment. Green hydrogen could help industrial sectors transition from fossil fuels. The problem is the water use. Audio und werbung/Shutterstock How much water would this use? According to the government’s modelling, making 15 million tonnes would require 740 billion litres of water. That would be about 7% of the 10,450 billion litres used by all of Australia’s households, farms, mines and black coal power plants. The government’s National Hydrogen Strategy shows the water use by major industries. Their total water use is 10,450 gigalitres annually. Department of Climate Change, Energy, the Environment and Water That’s substantial. One and a half Sydney Harbours worth, every year. But it might be a major underestimate. After all, estimates on indirect water use differ widely. The government’s figures are at the very bottom of the range. For instance, the latest research gives water consumption figures of about 66 litres per kilogram – more than twice as large. Other sources give values between 90 and 300 litres per kilogram of hydrogen – three to ten times higher. Uncertainty in modelling is normal. But the wide research suggesting much higher water use should give rise to real concern. If we take a middle-of-the-range figure of 95 litres per kilogram, this would mean that making 15 million tonnes of green hydrogen would use up 22% of the 10,450 billion litres used by households, farms, mines and black coal power plants annually by 2050. If hydrogen was even thirstier at 310 litres per kilogram, that would translate to 72% of that figure. These estimates are enormous. Even under the most optimistic scenario, the draw on Australia’s scarce freshwater resources would simply be too much. Where would this water come from? Farmers? Groundwater? Environmental flows from rivers? As the Queensland Farmers Federation pointed out in its response to the hydrogen strategy, the figures on water use “beg the question if they are in fact sustainable”. The Water Services Association of Australia has called for much greater attention to the water demands of green hydrogen, which it says are “often seriously underestimated”. What about saltwater? Australia has no shortage of oceans. The problem here becomes energy and wastewater. Desalination is still very energy intensive. Converting saltwater to fresh also produces large volumes of super-salty brine, which must then be managed as waste. Which way forward? Does this mean green hydrogen is a non-starter? Not necessarily. Improved electrolyser technology might offer ways to slash water use, while circular economy approaches such as resource recovery from brine could also reduce losses. But these concerns about water must be front and centre in future discussions about the shape and size of the industry in Australia.

Provocative new book says we must persuade people to have more babies

The population is set to plummet and we don't know how to stop it, warn Dean Spears and Michael Geruso in their new book, After the Spike

A large population may enable innovation and economies of scalePHILIPPE MONTIGNY/iStockphoto/Get​ty Images After the SpikeDean Spears and Michael Geruso (Bodley Head (UK); Simon & Schuster (US)) Four-Fifths of all the humans who will ever be born may already have been born. The number of children being born worldwide each year peaked at 146 million in 2012 and has been falling overall ever since. This means that the world’s population will peak and start to fall around the 2080s. This fall won’t be gradual. With birth rates already well below replacement levels in many countries including China and India, the world’s population will plummet as fast as it rose. In three centuries, there could be fewer than 2 billion people on Earth, claims a controversial new book. “No future is more likely than that people worldwide choose to have too few children to replace their own generation. Over the long run, this would cause exponential population decline,” write economists Dean Spears and Michael Geruso in After the Spike: The risks of global depopulation and the case for people. This, you might think, could be a good thing. Won’t it help solve many environmental issues facing us today? No, say the authors. Take climate change: their argument isn’t that population size doesn’t matter, but that it changes so slowly that other factors such as how fast the world decarbonises matter far more. The window of opportunity for lowering carbon dioxide emissions by reducing population has largely passed, they write. Spears and Geruso also make the case that there are many benefits to having a large population. For instance, there is more innovation, and economies of scale make the manufacture of things like smartphones feasible. “We get to have nice phones only because we have a lot of neighbors on this planet,” they write. So, in their view, our aim should be to stabilise world population rather than letting it plummet. The problem is we don’t know how, even with the right political will. As we grow richer, we are more reluctant to abandon career and leisure opportuntiies to have children While some government policies have had short-term effects, no country has successfully changed long-term population trends, argue the authors. Take China’s one-child policy. It is widely assumed to have helped reduce population growth – but did it? Spears and Geruso show unlabelled graphs of the populations of China and its neighbours before, during and after the policy was in place, and ask the reader which is China. There is no obvious difference. Attempts to boost falling fertility rates have been no more successful, they say. Birth rates jumped after Romania banned abortion in 1966, but they soon started to fall again. Sweden has tried the carrot rather than the stick by heavily subsidising day care. But the fertility rate there has been falling even further below the replacement rate. All attempts to boost fertility by providing financial incentives are likely to fail, Spears and Geruso argue. While people might say they are having fewer children because they cannot afford larger families, the global pattern is, in fact, that as people become richer they have fewer children. Rather than affordability being the issue, it is more about people deciding that they have better things to do, the authors say. As we grow richer, we are more reluctant to abandon career and leisure opportunities to have children. Even technological advances are unlikely to reverse this, they say. On everything other than the difficulty of stabilising the population, this is a relentlessly optimistic book. For instance, say the authors, dire predictions of mass starvation as the world’s population grew have been shown to be completely wrong. The long-term trend of people living longer and healthier lives can continue, they suggest. “Fears of a depleted, overpopulated future are out of date,” they write. Really? Spears and Geruso also stress that the price of food is key to determining how many go hungry, but fail to point out that food prices are now climbing, with climate change an increasing factor. I’m not so sure things are going to keep getting better for most people. This book is also very much a polemic: with Spears and Geruso labouring their main points, it wasn’t an enjoyable read. That said, if you think that the world’s population isn’t going to fall, or that it will be easy to halt its fall, or that a falling population is a good thing, you really should read it.

Summer of Change: New Books to Inspire Environmental Action

America’s summer celebrations are upon us, and these eight books will inspire environmentalists to act for our country and our planet. The post Summer of Change: New Books to Inspire Environmental Action appeared first on The Revelator.

“A patriot…wants the nation to live up to its ideals, which means asking us to be our best selves. A patriot must be concerned with the real world, which is the only place where their country can be loved and sustained. The patriot has universal values, standards by which they judge their nation, always wishing it well — and wishing that it would do better.” — Timothy Snyder, On Tyranny It’s the summer season: Barbeques are firing up, the stars and stripes are in view, and people are preparing to make a difference in the second half of the year. As we look to the “patriotic threesome” of holidays celebrated across the United States — Memorial Day, the Fourth of July, and Labor Day — it’s a good time to ask how you’ll show your patriotism for the planet. It’s especially important this year, given the current wave of misappropriation and compromises facing our natural lands and resources. Eight new environmental books might offer you some ideas on how to accomplish that. They offer ideas for getting involved in politics, improving your activism, and making important changes in your homes and communities. We’ve excerpted the books’ official descriptions below and provided links to the publishers’ sites, but you should also be able to find these books in a variety of formats through your local bookstore or library. Tools to Save Our Home Planet: A Changemaker’s Guidebook edited by Nick Mucha, Jessica Flint, and Patrick Thomas The need for activism is more urgent than ever before and the risks are greater, too. Safe and effective activism has always required smart strategic planning, clear goals and creative tactics, and careful and detailed preparation. Without these, activists can end up injured, penalized, or jailed. If anything, these risks are greater today as powerful forces in government and industry resist the big changes needed to slow the climate crisis and keep Earth livable for generations to come. Tools to Save Our Home Planet: A Changemaker’s Guidebook reflects the wisdom and best advice from activists working in today’s volatile world. A go-to resource for driving change, it offers timely and relevant insights for purpose-aligned work. It is intended as a primer for those new to activism and a refresher for seasoned activists wanting to learn from their peers, a reassuring and inspirational companion to the environmental and justice movements that we desperately need as a society. When We’re in Charge: The Next Generation’s Guide to Leadership by Amanda Litman Most leadership books treat millennials and Gen Z like nuisances, focusing on older leadership constructs. Not this one. When We’re in Charge is a no-bullshit guide for the next generation of leaders on how to show up differently, break the cycle of the existing workplace. This book is a vital resource for new leaders trying to figure out how to get stuff done without drama. Offering solutions for today’s challenges, Litman offers arguments for the four-day workweek, why transparency is a powerful tool, and why it matters for you to both provide and take family leave. A necessary read for all who occupy or aspire to leadership roles, this book is a vision for a future where leaders at work are compassionate, genuine, and effective. Scientists on Survival: Personal Stories of Climate Action by Scientists for XR In this important and timely book, scientists from a broad range of disciplines detail their personal responses to climate change and the ecological crises that led them to form Scientists for XR [Extinction Rebellion] and work tirelessly within it. Whether their inspiration comes from education or activism, family ties or the work environment, the scientists writing here record what drives them, what non-violent direct action looks like to them, what led them to become interested in the environmental crisis that threatens us all, and what they see as the future of life on Earth. Public Land and Democracy in America: Understanding Conflict over Grand Staircase-Escalante National Monument by Julie Brugger Public Land and Democracy in America brings into focus the perspectives of a variety of groups affected by conflict over the monument, including residents of adjacent communities, ranchers, federal land management agency employees, and environmentalists. In the process of following management disputes at the monument over the years, Brugger considers how conceptions of democracy have shaped and been shaped by the regional landscape and by these disputes. Through this ethnographic evidence, Brugger proposes a concept of democracy that encompasses disparate meanings and experiences, embraces conflict, and suggests a crucial role for public lands in transforming antagonism into agonism. The State of Conservation: Rural America and the Conservation-Industrial Complex since 1920 by Joshua Nygren In the twentieth century, natural resource conservation emerged as a vital force in U.S. politics, laying the groundwork for present-day sustainability. Merging environmental, agricultural, and political history, Nygren examines the political economy and ecology of agricultural conservation through the lens of the “conservation-industrial complex.” This evolving public-private network — which united the U.S. Department of Agriculture, Congress, local and national organizations, and the agricultural industry — guided soil and water conservation in rural America for much of the century. Contrary to the classic tales of U.S. environmental politics and the rise and fall of the New Deal Order, this book emphasizes continuity. Nygren demonstrates how the conservation policies, programs, and partnerships of the 1930s and 1940s persisted through the age of environmentalism, and how their defining traits anticipated those typically associated with late twentieth-century political culture. Too Late to Awaken: What Lies Ahead When There Is No Future by Slavoj Žižek We hear all the time that we’re moments from doomsday. Around us, crises interlock and escalate, threatening our collective survival: Russia’s invasion of Ukraine, with its rising risk of nuclear warfare, is taking place against a backdrop of global warming, ecological breakdown, and widespread social and economic unrest. Protestors and politicians repeatedly call for action, but still we continue to drift towards disaster. We need to do something. But what if the only way for us to prevent catastrophe is to assume that it has already happened — to accept that we’re already five minutes past zero hour? Too Late to Awaken sees Slavoj Žižek forge a vital new space for a radical emancipatory politics that could avert our course to self-destruction. He illuminates why the liberal Left has so far failed to offer this alternative, and exposes the insidious propagandism of the fascist Right, which has appropriated and manipulated once-progressive ideas. Pithy, urgent, gutting and witty Žižek’s diagnosis reveals our current geopolitical nightmare in a startling new light, and shows how, in order to change our future, we must first focus on changing the past. How We Sold Our Future: The Failure to Fight Climate Change by Jens Beckert For decades we have known about the dangers of global warming. Nevertheless, greenhouse gas emissions continue to increase. How can we explain our failure to take the necessary measures to stop climate change? Why are we so reluctant to act? Beckert provides an answer to these questions. Our apparent inability to implement basic measures to combat climate change is due to the nature of power and incentive structures affecting companies, politicians, voters, and consumers. Drawing on social science research, he argues that climate change is an inevitable product of the structures of capitalist modernity which have been developing for the past 500 years. Our institutional and cultural arrangements are operating at the cost of destroying the natural environment and attempts to address global warming are almost inevitably bound to fail. Temperatures will continue to rise, and social and political conflicts will intensify. We are selling our future for the next quarterly figures, the upcoming election results, and today’s pleasure. Any realistic climate policy needs to focus on preparing societies for the consequences of escalating climate change and aim at strengthening social resilience to cope with the increasingly unstable natural world. Parenting in a Climate Crisis: A Handbook for Turning Fear into Action by Bridget Shirvell In this urgent parenting guide, learn how to navigate the uncertainty of the climate crisis and keep your kids informed, accountable, and hopeful — with simple actions you can take as a family to help the earth. Kids today are experiencing the climate crisis firsthand. Camp canceled because of wildfire smoke. Favorite beaches closed due to erosion. Recess held indoors due to extreme heat. How do parents help their children make sense of it all? And how can we keep our kids (and ourselves) from despair? Environmental journalist and parent Bridget Shirvell has created a handbook for parents to help them navigate these questions and more, weaving together expert advice from climate scientists, environmental activists, child psychologists, and parents across the country. She helps parents answer tough questions (how did we get here?) and raise kids who feel connected to and responsible for the natural world, feel motivated to make ecologically sound choices, and feel empowered to meet the challenges of the climate crisis—and to ultimately fight for change. Enjoy these summer reads throughout the holidays and get involved with activities and protests that support our environment and wildlife. Whether it’s changing the way you celebrate to more sustainable fun or joining environmental summer pursuits, we hope you’ll make good trouble this holiday season.

Alabama Utility Commission Allowed to Hike Prices Behind Closed Doors, Judge Rules

A judge has ruled that Alabama's Public Service Commission can continue holding private meetings to decide fuel price hikes

MONTGOMERY, Ala. (AP) — Alabama's utility regulators can continue to hold closed-door meetings to determine price hikes, in an apparent departure from common practices in neighboring states, a circuit court judge ruled.The decision on Monday rejected a lawsuit filed by Southern Environmental Law Center on behalf of Energy Alabama, a nonprofit that advocates for renewable energy sources. The watchdog group was denied access to two meetings in 2024 where the public service commission decided how Alabama Power — the state's largest electricity provider — should adjust prices based on volatility in global fuel costs. Montgomery circuit Judge Brooke Reid ruled against the environmental advocates in a one-page order after a hearing in June. She said the group's rights had not been substantially violated. At the June hearing, Reid said the commission’s “interpretation of its own rules should be given deference.”Christina Tidwell, a senior attorney for the Southern Environmental Law Center, blasted Reid’s decision in a statement on Monday.“While other Southern states have meaningful public engagement in fuel cost proceedings, Alabama Power customers will continue to be shut out of the process,” Tidwell wrote. The Alabama Public Service Commission has rules that govern how Alabama Power can change electricity prices to offset increases in fuel costs, which tend to be volatile. Those rules say that the public is entitled to hear evidence and participate in proceedings that adjust fuel costs to ensure these changes are “just and reasonable.”The lawsuit said there have been only two public fuel cost hearings since the commission’s current rules were adopted in 1981. By contrast, the Georgia Public Service Commission, which regulates a sister company of Alabama Power, has held at least 26 public formal fuel cost proceedings, according to the complaint.The last public meeting in Alabama was called because the 2008 financial crisis caused fuel prices to skyrocket rapidly, according to attorneys for the state commission. They argued that the commission hasn't technically initiated a new proceeding since that change 16 years ago, even though rates have been adjusted over 15 times since then, so they are not compelled to invite public input.Attorneys for the state also argued that the public has “plenty of opportunities for input” even without public meetings, because the commission publishes monthly reports on fuel prices online, and rate changes are subject to public appeal. Alabama Power is a subsidiary of Atlanta-based Southern Company, which reported $4.4 billion in profit in 2024, according to annual shareholder reports. Alabama Power serves about 1.5 million of the state’s roughly 5 million residents.Most Alabama residents get electricity through municipal or cooperatively owned utilities. In 2023, the average Alabama Power consumer was paying about $159 per month, compared to the statewide average of approximately $132 per month, according to the most recent data from the U.S. Energy Information Administration. Alabama Power did not respond to an emailed request for comment on Wednesday afternoon inquiring about recent rates.After the ruling, Energy Alabama's executive director Daniel Tait said in a statement that the decision was “disappointing” for “Alabamians who have no choice but to pay the high cost of fossil fuels on their Alabama Power bill.”Riddle is a corps member for The Associated Press/Report for America Statehouse News Initiative.

‘This is a fight for life’: climate expert on tipping points, doomerism and using wealth as a shield

Economic assumptions about risks of the climate crisis are no longer relevant, says the communications expert Genevieve GuentherClimate breakdown can be observed across many continuous, incremental changes such as soaring carbon dioxide levels, rising seas and heating oceans. The numbers creep up year after year, fuelled by human-caused greenhouse gas emissions.But scientists have also identified at least 16 “tipping points” – thresholds where a tiny shift could cause fundamental parts of the Earth system to change dramatically, irreversibly and with potentially devastating effects. These shifts can interact with each other and create feedback loops that heat the planet further or disrupt weather patterns, with unknown but potentially catastrophic consequences for life on Earth. It is possible some tipping points may already have been passed. Continue reading...

Climate breakdown can be observed across many continuous, incremental changes such as soaring carbon dioxide levels, rising seas and heating oceans. The numbers creep up year after year, fuelled by human-caused greenhouse gas emissions.But scientists have also identified at least 16 “tipping points” – thresholds where a tiny shift could cause fundamental parts of the Earth system to change dramatically, irreversibly and with potentially devastating effects. These shifts can interact with each other and create feedback loops that heat the planet further or disrupt weather patterns, with unknown but potentially catastrophic consequences for life on Earth. It is possible some tipping points may already have been passed.Dr Genevieve Guenther, an American climate communications specialist, is the founding director of End Climate Silence, which studies the representation of global heating in the media and public discourse. Last year, she published The Language of Climate Politics: Fossil Fuel Propaganda and How to Fight It, which was described by Bill McKibben as “a gift to the world”. In the run-up to the Global Tipping Points conference in July, Guenther talks to the Guardian about the need to discuss catastrophic risks when communicating about the climate crisis.The future of her son and all children motivates Dr Genevieve Guenther to protect the planet from further global heating. Photograph: Laila Annmarie Stevens/The GuardianThe climate crisis is pushing globally important ecosystems – ice sheets, coral reefs, ocean circulation and the Amazon rainforest – towards the point of no return. Why is it important to talk about tipping points? We need to correct a false narrative that the climate threat is under control. These enormous risks are potentially catastrophic. They would undo the connections between human and ecological systems that form the basis of all of our civilisation.How have attitudes changed towards these dangers? There was a constructive wave of global climate alarm in the wake of the Intergovernmental Panel on Climate Change (IPCC) report on 1.5C in 2018. That was the first time scientists made it clear that the difference between 1.5C and 2C would be catastrophic for millions of people and that in order to halt global heating at a relatively safe level, we would need to start zeroing out our emissions almost immediately. Until then, I don’t think policymakers realised the timeline was that short. This prompted a flurry of activism – Greta Thunberg and Indigenous and youth activists – and a surge of media attention. All of this converged to make almost everybody feel that climate change was a terrifying and pressing problem. This prompted new pledges, new corporate sustainability targets, and new policies being passed by government.This led to a backlash by those in the climate movement who prefer to cultivate optimism. Their preferred solution was to drive capitalist investment into renewable technologies so fossil fuels could be beaten out of the marketplace. This group believed climate fear might drive away investors, so they started to argue it was counterproductive to talk about worst-case scenarios. Some commentators even argued we had averted the direst predictions and were now on a more reassuring trajectory of global warming of a little under 3C by 2100.There is a misconception that wealthier places, such as the UK, Europe (including Italy, pictured) and the US will not be affected by the climate crisis but this is wrong, says Guenther. Photograph: Tiziana Fabi/AFP/Getty ImagesBut it is bananas to feel reassured by that because 3C would be a totally catastrophic outcome for humanity. Even at the current level of about 1.5C, the impacts of warming are emerging on the worst side of the range of possible outcomes and there is growing concern of tipping points for the main Atlantic Ocean circulation (Amoc), Antarctic sea ice, corals and rainforests.If the risk of a plane crashing was as high as the risk of the Amoc collapsing, none of us would ever fly because they would not let the plane take off. And the idea that our little spaceship, our planet, is under the risk of essentially crashing and we’re still continuing business as usual is mindblowing. I think part of the problem is that people feel distant from the dangers and don’t realise the children we have in our homes today are threatened with a chaotic, disastrous, unliveable future. Talking about the risks of catastrophe is a very useful way to overcome this kind of false distance.In your book, you write that it’s appropriate to be scared and the more you know, the more likely you are to be worried, as is evident from the statements of scientists and the United Nations secretary general, António Guterres. Why? Some people at the centre of the media, policymaking and even research claim that climate change isn’t going to be that bad for those who live in the wealthy developed world – the UK, Europe and the United States. When you hear these messages, you are lulled into a kind of complacency and it seems reasonable to think that we can continue to live as we do now without putting ourselves, our families, our communities under threat within decades. What my book is designed to do is wake people up and raise the salience and support for phasing out fossil fuels.[It] is written for people who are already concerned about the climate crisis and are willing to entertain a level of anxiety. But the discourse of catastrophe would not be something I would recommend for people who are disengaged from the climate problem. I think that talking about catastrophe with those people can actually backfire because it’ll just either overwhelm them or make them entrench their positions. It can be too threatening.The Donnie Creek wildfire burns in British Columbia, Canada, in 2023. Photograph: Noah Berger/APA recent Yale study found that a degree of climate anxiety was not necessarily bad because it could stir people to collective action. Do you agree? It depends. I talk about three different kinds of doomerism. One is the despair that arises from misunderstanding the science and thinking we’re absolutely on the path to collapse within 20 or 30 years, no matter what we do. That is not true.Second, there’s a kind of nihilistic position taken by people who suggest they are the only ones who can look at the harsh truth. I have disdain for that position.Finally, there’s the doomerism that comes from political frustration, from believing that people who have power are just happy to burn the world down. And that to me is the most reasonable kind of doomerism. To address that kind of doomerism, you need to say: “Yes, this is scary as hell. But we must have courage and turn our fear into action by talking about climate change with others, by calling our elected officials on a regular basis, by demanding our workplaces put their money where their mouth is.”You need to acknowledge people’s feelings, meet them where they are and show how they can assuage their fear by cultivating their bravery and collective action.The most eye-opening part of your book was about the assumptions of the Nobel prize winner William Nordhaus that we’ll probably only face a very low percentage of GDP loss by the end of the century. This surely depends on ignoring tipping points? The only way Nordhaus can get the result that he does is if he fails to price the risk of catastrophe and leaves out a goodly chunk of the costs of global heating. In his models, he does not account for climate damages to labour productivity, buildings, infrastructure, transportation, non-coastal real estate, insurance, communication, government services and other sectors. But the most shocking thing he leaves out of his models is the risk that global heating could set off catastrophes, whether they are physical tipping points or wars from societal responses. That is why the percentage of global damages that he estimates is so ridiculously lowballed.The idea that climate change will just take off only a small margin of economic growth is not founded on anything empirical. It’s just a kind of quasi-religious faith in the power of capitalism to decouple itself from the planet on which it exists. That’s absurd and it’s unscientific.Some economists suggest wealth can provide almost unlimited protection from catastrophe because it is better to be in a steel and concrete building in a storm than it is to be in a wooden shack. How true is that? There’s no evidence that these protections are unlimited, though there are economists who suggest we can always substitute technologies or human-made products for ecosystems or even other planets like Mars for Earth itself. This goes back to an economic growth theorist named Robert Solow, who claims technological innovation can increase human productivity indefinitely. He stressed that it was just a theory, but the economists advising Ronald Reagan and Margaret Thatcher in the 1980s took this as gospel and argued it was possible to ignore environmental externalities – the costs of our economic system, including our greenhouse gas pollution – because you could protect yourself as long as you kept increasing your wealth.Floods due to heavy rains at Porto Alegre airport left a plane stranded on the runway in Rio Grande do Sul, Brazil, last year. Photograph: Diego Vara/ReutersExcept when it comes to the climate crisis? Yes, the whole spectacle of our planet heating up this quickly should call all of those economic assumptions into question. But because climate change is affecting the poor first and worst, this is used as evidence that poverty is the problem. This is a misrepresentation of reality because the poor are not the only ones who are affected by the climate crisis. This is a slow-moving but accelerating crisis that will root and spread. And it could change for the worst quite dramatically as we hit tipping points.The difference between gradual warming and tipping points is similar to the difference between chronic, manageable ailments and acute, life-threatening diseases, isn’t it? Yes. When people downplay the effects of climate change, they often represent the problem as a case of planetary diabetes – as if it were a kind of illness that you can bumble along with, but still have a relatively good quality of life as long as you use your technologies, your insulin, whatever, to sustain your health. But this is not how climate scientists represent climate change. Dr Joelle Gergis, one of the lead authors on the latest IPCC report, prefers to represent climate change as a cancer – a disease that takes hold and grows and metastasises until the day when it is no longer curable and becomes terminal. You could also think of that as a tipping point.This is a fight for life. And like all fights, you need a tremendous amount of bravery to take it on. Before I started working on climate change, I didn’t think of myself as a fighter, but I became one because I felt I have a responsibility to preserve the world for my son and children everywhere. That kind of fierce protectiveness is part of the way that I love. We can draw on that to have more strength than our enemies because I don’t think they’re motivated by love. I believe love is an infinite resource and the power of it is greater than that of greed or hate. If it weren’t, we wouldn’t be here.Tipping points: on the edge? – a series on our future Composite: Getty/Guardian DesignTipping points – in the Amazon, Antarctic, coral reefs and more – could cause fundamental parts of the Earth system to change dramatically, irreversibly and with devastating effects.

Costa Rica Loses Ocean Award Amid Shark Conservation Controversy

Following recent statements by Costa Rica’s Minister of Environment, Franz Tattenbach, international organizations Fins Attached and Marine Watch International, in association with the Rob Stewart Sharkwater Foundation, have announced the revocation of the 2024 Oceans Advocate Rob Stewart Award, which had been presented to Costa Rica in November of last year. The decision follows Tattenbach’s remarks describing the organizations’ post-award cooperation proposal as “blackmail.” He stated, “No aceptamos premios internacionales condicionados,” emphasizing that Costa Rica’s environmental policy “is not for sale.” In response, the organizations accused the minister of failing to honor commitments made during the award process. These included advancing marine conservation through technological and scientific cooperation, protecting critical marine habitats, and strengthening protections for endangered species like hammerhead sharks. “Promises made by the minister were not only broken but abandoned,” the organizations stated. “Meaningful recognition must be earned through demonstrable action and accountability.” Fins Attached rejected the “blackmail” characterization, clarifying that their proposal was a good-faith offer of scientific and logistical support to advance marine conservation. The revocation adds to growing criticism of Costa Rica’s marine policies, with a 2024 Environment Ministry report highlighting a 15% decline in marine biodiversity since 2018, attributed partly to lax fishing regulations. The organizations also cited a report by the International Fund for Animal Welfare (IFAW), which identifies Costa Rica as the top Latin American exporter of shark fins to Asian markets between 2003 and 2020, with over 5,600 metric tons exported. In 2025, the Center for the Rescue of Endangered Marine Species (CREMA) denounced the authorization of 12.6 tons of hammerhead shark fins transferred from Nicaragua through Costa Rica for re-export between September 2023 and September 2024. Minister Tattenbach has since stated that the Executive Branch has begun including a ban on the transit of hammerhead sharks and their parts through Costa Rican territory, aiming to prevent the country from being used as a trafficking route for hammerhead sharks.

Climate Activist Throws Bright Pink Paint on Glass Covering Picasso Painting in Montreal

The stunt is part of an environmental organization's efforts to draw attention to the dangerous wildfires spreading through Canada

Climate Activist Throws Bright Pink Paint on Glass Covering Picasso Painting in Montreal The stunt is part of an environmental organization’s efforts to draw attention to the dangerous wildfires spreading through Canada The activist threw paint on Pablo Picasso’s L'hétaïre (1901). Last Generation Canada A climate activist threw pink paint at Pablo Picasso’s L’hétaïre (1901) at the Montreal Museum of Fine Arts last week. The 21-year-old man, identified as Marcel, is a member of Last Generation Canada, an environmental organization that works to combat climate change. After splashing Picasso’s portrait with the paint, Marcel made a speech in French to the gallery, which was captured on video and posted on social media by Last Generation Canada. “There are more than 200 wildfires in Canada at this moment, 83 of which are not protected [and] which are out of control,” he said. “There are too many problems here. There are people who are dying. … If Canada doesn’t do much, soon we will all be dying.” Quick fact: Picasso’s blue period Pablo Picasso created L’hétaïre during his famous “blue period,” when the artist painted monochromatic artworks in shades of blue and blue-green. Canada is in the midst of its wildfire season, which occurs between April and October. The blazes have consumed almost nine million acres across four Canadian provinces, report the New York Times’ Nasuna Stuart-Ulin and Vjosa Isai. This season is a particularly bad one. In early June, satellite data revealed that the number of fire hotspots was four times higher than normal, per the Associated Press’ M.K. Wildeman. Marcel’s stunt is part of a three-week “action phase” by Last Generation Canada, according to a statement from the organization. The group is demanding that the Canadian government form a “Climate Disaster Protection Agency” to aid those “whose homes, communities, lives and livelihoods have been destroyed by extreme weather, including wildfires worsened by the burning of fossil fuels.” Picasso’s L’hétaïre, which was on loan from the Pinacoteca Agnelli in Turin, Italy, was covered by a layer of protective glass, and the pink paint caused no visible damage, according to a statement from the museum. Two museum security guards confronted Marcel and turned him over to the Montreal police. Officials tell Hyperallergic’s Maya Pontone that Marcel has been released from custody and will later appear in court. “It is most unfortunate that this act carried out in the name of environmental activism targeted a work belonging to our global cultural heritage and under safekeeping for the benefit of future generations,” Stéphane Aquin, the director of the museum, says in the statement. “Museums and artists alike are allies in the fight for a better world.” In recent years, damaging the glass protecting famous artworks has become a popular method of protest among some climate change groups. However, one of the best-known groups, a British organization called Just Stop Oil, announced in March that it would start winding down such tactics after the United Kingdom decided to stop issuing new oil and gas licenses. “We value paint strokes and color composition over life itself,” Marcel says in the statement from Last Generation Canada. “A lot more resources have been put in place to secure and protect this artwork than to protect living, breathing people.” The Montreal Museum of Fine Arts was displaying L’hétaïre as part of the exhibition “Berthe Weill, Art Dealer of the Parisian Avant-Garde,” focused on the 20th-century French gallery-owner who exhibited Picasso’s early work. After the June 19 incident, the museum was closed for a short period before reopening later that day. L’hétaïre has not yet returned to the gallery. “I am not attacking art, nor am I destroying it. I am protecting it,” says Marcel in a social media post by Last Generation Canada. “Art, at its core, is depictions of life. It is by the living, for the living. There is no art on a dead planet.” Get the latest stories in your inbox every weekday.
