American government built the meat industry. Now can it build a better food system?

News Feed
Friday, August 9, 2024

Over the last decade, it seemed possible for animal welfare advocates to dream that the US might be on the cusp of a meat-free revolution. The plant-based meat maker Beyond Meat’s valuation soared after it debuted on the stock market in 2019, a bet on future growth. Oatly couldn’t produce enough of its dairy-free milk to keep up with demand, and plant-based Impossible Burgers were being served at both high-end restaurants and fast food chains like White Castle and Burger King. In 2020, Impossible Foods founder Pat Brown even declared that the world could replace the use of animals altogether for food by 2035.  But much of that optimism has since curdled into pessimism. Sales in the alternative meat sector have slowed and a number of startups have perished, leading multiple news outlets to eulogize the nascent industry. The industry’s problems can largely be chalked up to the cold hard fact that so far, it’s failed in its fundamental proposition: Consumers don’t think their products taste good enough to forgo conventional meat. Premature media hype, meat industry-funded attack ads, high price tags, and a flurry of imitators flooding the market with mediocre or downright bad products don’t help, either. This story is part of How Factory Farming Ends Read more from this special package analyzing the long fight against factory farming here. This series is supported by Animal Charity Evaluators, which received a grant from Builders Initiative. The essential problem that plant-based meat was supposed to solve remains unchanged. Per capita, US meat consumption is only projected to increase over the next decade, even as climate scientists say meat and dairy consumption in rich countries must decline rapidly to meet global climate targets.  The initial enthusiasm for plant-based meat was rooted in the idea that it was a more promising path to end the factory farming of animals than traditional activism. Instead of changing people’s minds about what to eat, plant-based entrepreneurs and advocates sought to change meat itself. Based on the numbers, the payback on that bet is mixed.  Grocery store plant-based meat sales in dollars soared from 2017 to 2021, but have since slightly declined. Even more troubling is the steep decline in the number of plant-based meat units sold at grocery stores, which fell 26 percent over the last two years (conventional meat sales dipped by just 6 percent over the same period). Plant-based meat sales in restaurants and cafeterias — along with grocery stores outside the US — have remained flat or grown only slowly over the past few years. But progress doesn’t always move in a straight line, and this could be a mere lull — a market correction after years of unstable growth and investor hype. In an attempt to jumpstart the plant-based industry again, a number of nonprofits and companies have set their sights on state legislatures and Capitol Hill, intensifying their lobbying to advance their cause (and bottom lines).  Some are focused on directing more R&D funding to “alternative protein,” an umbrella term that encompasses plant-based products, like those from Oatly and Beyond Meat, along with high-tech fermentation and lab-grown or “cell-cultivated” meat — real meat made by directly growing animal cells, without the slaughter of a cow, chicken, pig or fish. Just as the federal government’s early R&D funding for solar and wind power helped deliver cheap, abundant renewable energy, alternative protein advocates say R&D funding could enable the sector to lower the prices and improve the taste and texture of its products. Some plant-based advocates are pushing in a more low-tech direction, working with schools and other federally-funded institutions to serve more beans, lentils, whole grains, and vegetables. Jessica Almy, head of government relations for the Good Food Institute, an organization that advocates for alternative protein, said her organization seeks to create a “level playing field” between the conventional meat industry and the animal-free upstarts. “The big idea here is that alternative proteins would compete in the free market,” she said, “and that consumers ultimately would decide the winners and the losers.”  Currently, the meat market is not so free. The meat and dairy industries, which are powerful forces in Washington, have long benefited from a sprawling web of subsidies, R&D programs, and government grants, receiving about 800 times more public funding than the alternative protein sector from 2014 to 2020 despite the far greater costs they exert on the environment.  “Our national policies continue to favor and fund high-emissions industries who promote unsustainable food systems and diets,” as Pearson Croney-Clark, public affairs manager for Oatly, put it in an email to Vox. Consumers’ choices are determined by a number of factors beyond taste and price, like our upbringing and social norms. The very idea of meat’s necessity at every meal is stubbornly engrained in America’s DNA, too. US factory farming has scaled to fulfill that belief, though the treatment of animals represents nothing short of a moral atrocity future generations will look back on in horror. We’ve long had a bounty of plant-based foods ready to replace much of it — think beans, lentils, whole grains, vegetables, and tofu — that might find more purchase among the American public if served up in more creative ways. Better tasting and more affordable plant-based meat products would help, too. To give the plant-based food movement a fighting chance to bring our food system in line with planetary boundaries, we have to shift a policy landscape that for too long has benefitted the foods that do the most harm to the environment, animals, and public health. The movement’s fledgling influence campaign has already shown that progress is possible, and its broader agenda — a number of incremental but promising reforms — holds potential to actually move the needle on American meat consumption.   Getting the next generation of meat alternatives from lab to table The cost of various clean energy technologies, such as solar panels and wind turbines, have plummeted in recent decades. We can thank the federal government, which funded early stage R&D, for much of that progress. That’s just as true for America’s highly industrialized meat and dairy industry, which has benefited from over a century of government support to build factory farming. Alternative protein advocates say investing more of America’s agricultural R&D budget in their sector could be crucial to improving products, and thereby increase their commercial viability. “Early stage R&D is more of a focus for this sector in particular because the products are so early in their development, and we think they can be so much better than they are,” Almy said.  Understanding how policy and industry shape our food choices As consumers, we like to think we have a lot of choice. But policymakers and meat industry lobbyists heavily influence our food system:  How public universities hooked America on meat How a shipping error more than a century ago launched the $30 billion chicken industry Big Milk has taken over American schools It’s not just Big Oil. Big Meat also spends millions to crush good climate policy. Have questions, comments, or ideas? Email me: kenny.torrella@voxmedia.com. Advocates like Almy are starting to get what they want. In 20212, Congress approved around $5 million annually for the USDA to conduct in-house alternative protein research, and it’s already been dispersed to agency labs around the country. Projects include investigating how different strains of lentils and chickpeas affect flavor, the functional properties of soybeans, and food safety measures.  It’s still a paltry 0.1 percent of the USDA’s $5 billion annual R&D budget. But it was a start. The USDA also recently funded university research into breeding a higher protein strain of fava beans and developing plant-based seafood, and the US Department of Defense has taken some interest in the sector, too. There’s also been movement at the state level: In 2022, California invested $5 million into alternative protein research at public universities, while Illinois has helped launch a biotechnology hub that will in part work on alternative protein projects.  R&D is even more crucial to cell-cultivated meat, which promises to provide precisely the same animal-based product consumers eat today — provided the cost can come down from the rafters. While the US government has approved two cell-cultivated meat companies to sell their products, they aren’t yet for sale. Startups still need to overcome a range of technical and economic challenges to scale up and compete with conventionally grown meat on cost, and some scientists believe they never will. Those challenges include making animal cells grow faster, preventing bacterial contamination, and building an affordable supply chain of feed for the cells. A couple cell-cultivated startups have gone under and several have laid off employees. Venture capitalists have poured around $3 billion across more than 150 startups globally, which sounds like a lot, but it’s a pittance compared to how much has been invested into other sustainable technologies. Considering the enormous difficulty in shifting consumers’ diets to be more climate friendly, cell-cultivated meat proponents say it’s more than worthy of government R&D funding. That has finally begun to trickle in. A few years ago, scientists at the University of California-Davis and Tufts University received millions of dollars from government agencies to study cell-cultivated meat. Sean Edgett, chief legal officer of Upside Foods — a large cell-cultivated meat startup — described these programs as doing important “table stakes” work, basic research that can help new companies get off the ground more easily and build a talent pipeline for companies like Upside. The alternative protein industry is working to expand the pot of federal and state research dollars through the next Farm Bill and other pieces of legislation. Rep. Julia Brownley (D-CA) introduced the PROTEIN Act last year, which would establish alternative protein research centers in at least three universities and a dedicated research program under the USDA. Meanwhile, Rep. Jim McGovern (D-MA) has introduced the PLANT Act to provide support for farmers who grow common ingredients in plant-based products and set up a program to help companies better market their products, similar to an existing USDA program for conventional dairy businesses.   Making school food climate-friendly With 5 billion meals served at school cafeterias each year through the National School Lunch Program, the lunch line has long been considered an opportunity to build a more healthy and sustainable food system.  But even in crunchy California, for example, meat and dairy dominates school food, with only 8 percent of entrees entirely plant-based. Evening out that ratio could help improve student health, as a more “flexitarian” diet — one lower in animal-based foods and higher in plant-based foods — can improve metabolic health and reduce risk of Type 2 diabetes, heart disease, and some cancers.  The US federal dietary guidelines report that children and teenagers tend to under-consume plant-based foods. Changing that, at least in the school cafeteria, would also increase kids’ intake of fiber, a critical nutrient that 95 percent of Americans don’t get enough of and is found only in plant foods. To that end, a coalition of environmental, public health, and animal welfare organizations recently secured a substantive win in the USDA’s recent updates to school nutrition standards. Those updates include giving schools more flexibility to serve beans, lentils, and tofu, allowing nuts and seeds to be served as a meat alternative, and allowing the option to serve hummus and other bean dips as a snack. “That increased flexibility is a real opportunity,” said Audrey Lawson-Sanchez, executive director of Balanced, a plant-based nutrition group in the coalition. “Now it really is going to be about making sure that [school] food service teams… actually have the skills and the resources” to act on the flexibility.  The demand is there, Lawson-Sanchez said, pointing to an Illinois law that went into effect last August which requires schools to serve plant-based meals to kids who request them. So far, she said, students at around 15 percent of the state’s 852 school districts have asked for them. Lawson-Sanchez’s group set up a pilot program at eight schools to help them meet those requests, and one was so successful that it now has one fully plant-based day per week and one 50 percent plant-based day per week.  But schools need money to implement new programs, and plant-based advocates have drawn inspiration from the USDA’s Farm to School grant program, which helps schools set up gardens and bring local food into K-12 cafeterias by working with farmers. A specifically plant-based version could be used to train school chefs, develop new recipes, and market new dishes to students; last year, Rep. Nydia M. Velázquez (D-NY) and Rep. Jamaal Bowman (D-NY) introduced a bill to fund such a program. Advocates and policymakers also see breaking Big Dairy’s iron grip on school food and making it easier to get dairy-free milk as a ripe opportunity for change. Currently, schools must at least offer cow’s milk at every meal and few carry plant-based options. One out of five elementary and middle schools participating in the National School Lunch Program go so far as to require all students to take cow’s milk, even though kids throw away nearly half of it, and many students — especially those of color — are lactose intolerant. If a kid wants a dairy-free option, like soy milk, they have to provide a note from a doctor or parent, depending on their reason.  Rep. Robert Scott (D-VA), ranking chair of the US House Committee on Education and the Workforce, which oversees school nutrition policy, wants to change that. A Democratic aide on that committee told Vox that Rep. Scott’s child nutrition reauthorization bill would loosen restrictions preventing students from getting plant milk alternatives, and set up a $2 million fund for schools to cover some of the cost of plant-based milk purchases. Advocates in the school food coalition also want to see the USDA encourage more plant-based options, allow high-protein grains like quinoa to count as a meat alternative, adopt minimum fiber standards, and make cow’s milk optional at all schools.  Beyond school lunches, the federal government directly buys billions of dollars of food each year for food banks, federal building cafeterias, and more. By one estimate, nearly 90 percent of the protein-rich foods it purchases are animal products. In recent years, there’s been an internal push at the Department of Defense — which makes up about half of federal food purchases — to shift some of its food to plant-based. Some military bases are serving more plant-based meals, and recent DoD nutrition standards now require legumes to be served every day at military base cafeterias.  In April, for the first time in a decade, the USDA updated its standards for the Women, Infant, and Children’s program — another major government food purchaser. The updates include a reduction in the amount of cow’s milk participants can purchase and more flexibility to buy plant-based dairy products and fruits and vegetables. Oatly saw it as a win, while a major dairy industry group said it was “disturbed” by the new rule.  Beyond federal agencies, other institutions can enact policies to put plant-based foods at the center of our plates. For example, New York City’s hospital system reduced its food carbon footprint by more than a third by making plant-based meals the default option, universities are increasing their meat-free offerings, and in some countries, major food companies have committed to making a larger share of their protein-rich products plant-based.  A level playing field for meat alternatives Following a playbook deployed by the fossil fuel industry against the renewable energy sector, the conventional meat and dairy industry and its legislative allies are now striving to hamstring its competition. Over a dozen states have passed laws to restrict how plant-based meat, dairy, and egg companies can label their products, with some banning usage of words like “sausage” or “cheese,” even if accompanied by clarifying phrases like “vegetarian,” “plant-based,” or “animal-free.” Some of those laws have been overturned or weakened, but state lawmakers — and members of Congress, too — continue to introduce new bills.  Legislative attacks against the cell-cultivated startups are more existential. Earlier this year, Florida and Alabama’s state legislatures banned the sale and production of cell-cultivated meat, and several other states have introduced bans. (In late June, days before the Florida ban took effect, Upside Foods gave out free cell-cultivated meat in Miami.)  At this point, the bans are purely symbolic, as cell-cultivated meat is nowhere near commercial viability.  Alternative protein producers want to stop these discriminatory regulations, but they also want to benefit from some of the government assistance that the conventional meat industry enjoys. One of those is low-interest federal loans, an unglamorous but potentially powerful tool for launching novel, capital-intensive technologies.  Take Tesla, for example. In 2010, the company got a $465 million loan from the US Department of Energy that it used to build a manufacturing plant that eventually brought the Model S to American roads. Cell-cultivated meat companies will likely need this level of government support to scale, too.  The US Department of Energy recently opened its loan application program to alternative protein companies, which could be a lifeline as venture capital funding has dried up across the economy. (Upside and its competitor GOOD Meat have paused plans to build out large manufacturing facilities.) Edgett said other federal loan programs should be expanded and made accessible to alternative protein companies, too.  He also wants to see a smoother regulatory process with the USDA and the US Food and Drug Administration, which share oversight of the cell-cultivated meat industry and must both sign off on new products. Upside Foods’ cell-cultivated chicken has already been approved for sale but many other companies still have applications waiting for action. Edgett said the two agencies “could just do more to make expectations clear” by publishing guidance for startups and establishing a uniform process for how these products will be labeled. Currently, he said, label approval is a one-off process for each company. The sector could receive some clarity later this year, as the USDA is expected to publish a proposed rule on the matter. “I’m really thinking about a lot of these cultivated meat companies that have such short runways, and they’re running out of capital,” Edgett said. “And I think they’ve hit a wall on the regulatory side, just because it’s slower than they expected, or it’s fairly opaque.” For any chance of success, alternative protein companies will need every obstacle moved out of their way, including what some consider to be a needlessly slow regulatory process. This may be especially important for startups whose products could be market-ready if only they had federal approval. For example, companies including Mission Barns, Meatable, and Mosa Meat aren’t seeking to produce 100 percent cell-cultivated meat or anything close to it, but rather, are making “hybrid” alternative meat — plant-based meat blended with a small percent of cell-based fat or protein to achieve a meatier flavor. These products in theory will be easier to scale and more affordable than their more purist competitors.   The movement for a food system with fewer animal products has had a tumultuous decade, and ultimately, lower prices and tastier products won’t guarantee it experiences another major upswing. But meat’s outsized carbon and pollution footprint has, thus far, been a gaping hole in America’s ambitious environmental plans. To make progress on those goals, policymakers will need to show a willingness to move in a more plant-based direction. If done correctly, that could ease the increasing politicization of meat. It could also determine whether the development of better plant-based meat becomes a viable path to changing the food system — or remains a niche category. 

Over the last decade, it seemed possible for animal welfare advocates to dream that the US might be on the cusp of a meat-free revolution.

A level playing field for meat alternatives

Following a playbook deployed by the fossil fuel industry against the renewable energy sector, the conventional meat and dairy industry and its legislative allies are now striving to hamstring its competition.

Over a dozen states have passed laws to restrict how plant-based meat, dairy, and egg companies can label their products, with some banning usage of words like “sausage” or “cheese,” even if accompanied by clarifying phrases like “vegetarian,” “plant-based,” or “animal-free.” Some of those laws have been overturned or weakened, but state lawmakers — and members of Congress, too — continue to introduce new bills.

Take Tesla, for example. In 2010, the company got a $465 million loan from the US Department of Energy that it used to build a manufacturing plant that eventually brought the Model S to American roads. Cell-cultivated meat companies will likely need this level of government support to scale, too. 

The US Department of Energy recently opened its loan application program to alternative protein companies, which could be a lifeline as venture capital funding has dried up across the economy. (Upside and its competitor GOOD Meat have paused plans to build out large manufacturing facilities.) Edgett said other federal loan programs should be expanded and made accessible to alternative protein companies, too. 

He also wants to see a smoother regulatory process with the USDA and the US Food and Drug Administration, which share oversight of the cell-cultivated meat industry and must both sign off on new products. Upside Foods’ cell-cultivated chicken has already been approved for sale but many other companies still have applications waiting for action.

Edgett said the two agencies “could just do more to make expectations clear” by publishing guidance for startups and establishing a uniform process for how these products will be labeled. Currently, he said, label approval is a one-off process for each company. The sector could receive some clarity later this year, as the USDA is expected to publish a proposed rule on the matter.

“I’m really thinking about a lot of these cultivated meat companies that have such short runways, and they’re running out of capital,” Edgett said. “And I think they’ve hit a wall on the regulatory side, just because it’s slower than they expected, or it’s fairly opaque.”

For any chance of success, alternative protein companies will need every obstacle moved out of their way, including what some consider to be a needlessly slow regulatory process. This may be especially important for startups whose products could be market-ready if only they had federal approval. For example, companies including Mission Barns, Meatable, and Mosa Meat aren’t seeking to produce 100 percent cell-cultivated meat or anything close to it, but rather, are making “hybrid” alternative meat — plant-based meat blended with a small percent of cell-based fat or protein to achieve a meatier flavor. These products in theory will be easier to scale and more affordable than their more purist competitors.  

The movement for a food system with fewer animal products has had a tumultuous decade, and ultimately, lower prices and tastier products won’t guarantee it experiences another major upswing. But meat’s outsized carbon and pollution footprint has, thus far, been a gaping hole in America’s ambitious environmental plans. To make progress on those goals, policymakers will need to show a willingness to move in a more plant-based direction. If done correctly, that could ease the increasing politicization of meat. It could also determine whether the development of better plant-based meat becomes a viable path to changing the food system — or remains a niche category.

Giant Sloths and Many Other Massive Creatures Were Once Common on Our Planet. With Environmental Changes, Such Giants Could Thrive Again

If large creatures like elephants, giraffes and bison are allowed to thrive, they could alter habitats that allow for the rise of other giants

Giant Sloths and Many Other Massive Creatures Were Once Common on Our Planet. With Environmental Changes, Such Giants Could Thrive Again If large creatures like elephants, giraffes and bison are allowed to thrive, they could alter habitats that allow for the rise of other giants Riley Black - Science Correspondent July 11, 2025 8:00 a.m. Ancient sloths lived in trees, on mountains, in deserts, in boreal forests and on open savannas. Some grew as large as elephants. Illustration by Diego Barletta The largest sloth of all time was the size of an elephant. Known to paleontologists as Eremotherium, the shaggy giant shuffled across the woodlands of the ancient Americas between 60,000 and five million years ago. Paleontologists have spent decades hotly debating why such magnificent beasts went extinct, the emerging picture involving a one-two punch of increasing human influence on the landscape and a warmer interglacial climate that began to change the world’s ecosystems. But even less understood is how our planet came to host entire communities of such immense animals during the Pleistocene. Now, a new study on the success of the sloths helps to reveal how the world of Ice Age giants came to be, and hints that an Earth brimming with enormous animals could come again. Florida Museum of Natural History paleontologist Rachel Narducci and colleagues tracked how sloths came to be such widespread and essential parts of the Pleistocene Americas and published their findings in Science this May. The researchers found that climate shifts that underwrote the spread of grasslands allowed big sloths to arise, the shaggy mammals then altering those habitats to maintain open spaces best suited to big bodies capable of moving long distances. The interactions between the animals and environment show how giants attained their massive size, and how strange it is that now our planet has fewer big animals than would otherwise be here. Earth still boasts some impressively big species. In fact, the largest animal of all time is alive right now and only evolved relatively recently. The earliest blue whale fossils date to about 1.5 million years ago, and, at 98 feet long and more than 200 tons, the whale is larger than any mammoth or dinosaur. Our planet has always boasted a greater array of small species than large ones, even during prehistoric ages thought of as synonymous with megafauna. Nevertheless, Earth’s ecosystems are still in a megafaunal lull that began at the close of the Ice Age. “I often say we are living on a downsized planet Earth,” says University of Maine paleoecologist Jacquelyn Gill.Consider what North America was like during the Pleistocene, between 11,000 years and two million ago. The landmass used to host multiple forms of mammoths, mastodons, giant ground sloths, enormous armadillos, multiple species of sabercat, huge bison, dire wolves and many more large creatures that formed ancient ecosystems unlike anything on our planet today. In addition, many familiar species such as jaguars, black bears, coyotes, white-tailed deer and golden eagles also thrived. Elsewhere in the world lived terror birds taller than an adult human, wombats the size of cars, woolly rhinos, a variety of elephants with unusual tusks and other creatures. Ecosystems capable of supporting such giants have been the norm rather than the exception for tens of millions of years. Giant sloths were among the greatest success stories among the giant-size menagerie. The herbivores evolved on South America when it was still an island continent, only moving into Central and North America as prehistoric Panama connected the landmasses about 2.7 million years ago. Some were small, like living two- and three-toed sloths, while others embodied a range of sizes all the way up to elephant-sized giants like Eremotherium and the “giant beast” Megatherium. An Eremotherium skeleton at the Houston Museum of Natural Science demonstrates just how large the creature grew. James Nielsen / Houston Chronicle via Getty Images The earliest sloths originated on South America about 35 million years ago. They were already big. Narducci and colleagues estimate that the common ancestor of all sloths was between about 150 and 770 pounds—or similar to the range of sizes seen among black bears today—and they walked on the ground. “I was surprised and thrilled” to find that sloths started off large, Narducci says, as ancestral forms of major mammal groups are often small, nocturnal creatures. The earliest sloths were already in a good position to shift with Earth’s climate and ecological changes. The uplift of the Andes Mountains in South America led to changes on the continent as more open, drier grasslands spread where there had previously been wetter woodlands and forests. While some sloths became smaller as they spent more time around and within trees, the grasslands would host the broadest diversity of sloth species. The grasslands sloths were the ones that ballooned to exceptional sizes. Earth has been shifting between warmer and wetter times, like now, and cooler and drier climates over millions of years. The chillier and more arid times are what gave sloths their size boost. During these colder spans, bigger sloths were better able to hold on to their body heat, but they also didn’t need as much water, and they were capable of traveling long distances more efficiently thanks to their size. “The cooler and drier the climate, especially after 11.6 million years ago, led to expansive grasslands, which tends to favor the evolution of increasing body mass,” Narducci says. The combination of climate shifts, mountain uplift and vegetation changes created environments where sloths could evolve into a variety of forms—including multiple times when sloths became giants again. Gill says that large body size was a “winning strategy” for herbivores. “At a certain point, megaherbivores get so large that most predators can’t touch them; they’re able to access nutrition in foods that other animals can’t really even digest thanks to gut microbes that help them digest cellulose, and being large means you’re also mobile,” Gill adds, underscoring advantages that have repeatedly pushed animals to get big time and again. The same advantages underwrote the rise of the biggest dinosaurs as well as more recent giants like the sloths and mastodons. As large sloths could travel further, suitable grassland habitats stretched from Central America to prehistoric Florida. “This is what also allowed for their passage into North America,” Narducci says. Sloths were able to follow their favored habitats between continents. If the world were to shift back toward cooler and drier conditions that assisted the spread of the grasslands that gave sloths their size boost, perhaps similar giants could evolve. The sticking point is what humans are doing to Earth’s climate, ecosystems and existing species. The diversity and number of large species alive today is vastly, and often negatively, affected by humans. A 2019 study of human influences on 362 megafauna species, on land and in the water, found that 70 percent are diminishing in number, and 59 percent are getting dangerously close to extinction. But if that relationship were to change, either through our actions or intentions, studies like the new paper on giant sloths hint that ecosystems brimming with a wealth of megafaunal species could evolve again. Big animals change the habitats where they live, which in turn tends to support more large species adapted to those environments. The giant sloths that evolved among ancient grasslands helped to keep those spaces open in tandem with other big herbivores, such as mastodons, as well as the large carnivores that preyed upon them. Paleontologists and ecologists know this from studies of how large animals such as giraffes and rhinos affect vegetation around them. Big herbivores, in particular, tend to keep habitats relatively open. Elephants and other big beasts push over trees, trample vegetation underfoot, eat vast amounts of greenery and transport seeds in their dung, disassembling vegetation while unintentionally planting the beginnings of new habitats. Such broad, open spaces were essential to the origins of the giant sloths, and so creating wide-open spaces helps spur the evolution of giants to roam such environments. For now, we are left with the fossil record of giant animals that were here so recently that some of their bones aren’t even petrified, skin and fur still clinging to some skeletons. “The grasslands they left behind are just not the same, in ways we’re really only starting to understand and appreciate,” Gill says. A 2019 study on prehistoric herbivores in Africa, for example, found that the large plant-eaters altered the water cycling, incidence of fire and vegetation of their environment in a way that has no modern equivalent and can’t just be assumed to be an ancient version of today’s savannas. The few megaherbivores still with us alter the plant life, water flow, seed dispersal and other aspects of modern environments in their own unique ways, she notes, which should be a warning to us to protect them—and the ways in which they affect our planet. If humans wish to see the origin of new magnificent giants like the ones we visit museums to see, we must change our relationship to the Earth first. Get the latest Science stories in your inbox.

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.”

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.

Hundreds of life-size animal puppets have begun a 20,000km (12,400 mile) journey from central Africa to the Arctic Circle as part of an ambitious project created by the team behind Little Amal, the giant puppet of a Syrian girl that travelled across the world.The public art initiative called The Herds, which has already visited Kinshasa and Lagos, will travel to 20 cities over four months to raise awareness of the climate crisis.It is the second major project from The Walk Productions, which introduced Little Amal, a 12-foot puppet, to the world in Gaziantep, near the Turkey-Syria border, in 2021. The award-winning project, co-founded by the Palestinian playwright and director Amir Nizar Zuabi, reached 2 million people in 17 countries as she travelled from Turkey to the UK.The Herds’ journey began in Kinshasa’s Botanical Gardens on 10 April, kicking off four days of events. It moved on to Lagos, Nigeria, the following week, where up to 5,000 people attended events performed by more than 60 puppeteers.On Friday the streets of Dakar in Senegal will be filled with more than 40 puppet zebras, wildebeest, monkeys, giraffes and baboons as they run through Médina, one of the busiest neighbourhoods, where they will encounter a creation by Fabrice Monteiro, a Belgium-born artist who lives in Senegal, and is known for his large-scale sculptures. On Saturday the puppets will be part of an event in the fishing village of Ngor.The Herds’ 20,000km journey began in Kinshasa, the Democratic Republic of the Congo. Photograph: Berclaire/walk productionsThe first set of animal puppets was created by Ukwanda Puppetry and Designs Art Collective in Cape Town using recycled materials, but in each location local volunteers are taught how to make their own animals using prototypes provided by Ukwanda. The project has already attracted huge interest from people keen to get involved. In Dakar more than 300 artists applied for 80 roles as artists and puppet guides. About 2,000 people will be trained to make the puppets over the duration of the project.“The idea is that we’re migrating with an ever-evolving, growing group of animals,” Zuabi told the Guardian last year.Zuabi has spoken of The Herds as a continuation of Little Amal’s journey, which was inspired by refugees, who often cite climate disaster as a trigger for forced migration. The Herds will put the environmental emergency centre stage, and will encourage communities to launch their own events to discuss the significance of the project and get involved in climate activism.The puppets are created with recycled materials and local volunteers are taught how to make them in each location. Photograph: Ant Strack“The idea is to put in front of people that there is an emergency – not with scientific facts, but with emotions,” said The Herds’ Senegal producer, Sarah Desbois.She expects thousands of people to view the four events being staged over the weekend. “We don’t have a tradition of puppetry in Senegal. As soon as the project started, when people were shown pictures of the puppets, they were going crazy.”Little Amal, the puppet of a Syrian girl that has become a symbol of human rights, in Santiago, Chile on 3 January.

Dead, sick pelicans turning up along Oregon coast

So far, no signs of bird flu but wildlife officials continue to test the birds.

Sick and dead pelicans are turning up on Oregon’s coast and state wildlife officials say they don’t yet know why. The Oregon Department of Fish and Wildlife says it has collected several dead brown pelican carcasses for testing. Lab results from two pelicans found in Newport have come back negative for highly pathogenic avian influenza, also known as bird flu, the agency said. Avian influenza was detected in Oregon last fall and earlier this year in both domestic animals and wildlife – but not brown pelicans. Additional test results are pending to determine if another disease or domoic acid toxicity caused by harmful algal blooms may be involved, officials said. In recent months, domoic acid toxicity has sickened or killed dozens of brown pelicans and numerous other wildlife in California. The sport harvest for razor clams is currently closed in Oregon – from Cascade Head to the California border – due to high levels of domoic acid detected last fall.Brown pelicans – easily recognized by their large size, massive bill and brownish plumage – breed in Southern California and migrate north along the Oregon coast in spring. Younger birds sometimes rest on the journey and may just be tired, not sick, officials said. If you find a sick, resting or dead pelican, leave it alone and keep dogs leashed and away from wildlife. State wildlife biologists along the coast are aware of the situation and the public doesn’t need to report sick, resting or dead pelicans. — Gosia Wozniacka covers environmental justice, climate change, the clean energy transition and other environmental issues.
