Humanity is failing one of its greatest moral tests

Wednesday, August 7, 2024

If you can stand to think about it long enough, the problem becomes paralyzing. Tens of billions of land animals slaughtered every year; hundreds of millions every day; thousands in the time it takes to read this sentence. The number grows by billions more every year, into multiples that feel as abysmal as they are mind-numbing.  On top of 80 billion, how can we comprehend another 5, 10, 20 billion more? How can it get worse? And while we can count suffering in the aggregate, these animals experience it as individuals, each one containing an infinite depth of conscious experience. Our human world is built atop a parallel universe of their misery, an inferno from which most of us prefer to look away.  But one tiny minority group, so often tuned out by the public, has been imploring us to look.  More than a year ago, my colleagues and I at Vox’s Future Perfect had the idea of launching a project that weighs the state of the movement against factory farming, a movement that has, for the last 50 years or so, fought valiantly to stanch the rise of an unprecedented system of organized violence against our fellow creatures.  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. What we found is that the fight sits at an uneasy inflection point: Animal rights activism and plant-based eating are more visible than ever; a handful of animal protection groups have managed to win major state and local animal welfare laws and extract concessions from mega-corporations. And yet, by any honest measure, the industrialized exploitation and abuse of animals is rapidly getting worse. Animal advocates are losing the fight. Meat consumption is rising relentlessly in the US and around the world. If you believe our most reputable pollsters, the share of Americans who call themselves vegetarian or vegan has largely remained static. Whatever gains animal advocates have achieved have not been enough to make a significant dent in the factory farm system or even limit its proliferation. All this is true despite the growing risks of climate change and pandemics, both of which are fueled by the meat and dairy industries. Not even out of self-preservation has humanity yet shown a willingness to eat fewer animals.  These trends reflect a tragic irony of human development: As our numbers and material wealth have swelled, so has the population of domesticated animals that we warehouse in merciless conditions and engineer to their biological limits. Animal advocates who attempt to change these conditions are up against centuries of entrenched cultural norms and identity, combined with ruthless agribusiness interests and captive political actors that tell us today’s unprecedented levels of meat consumption are natural, necessary, and above all else, inevitable. But there is nothing natural about what we have built. One of the most honest accounts I’ve encountered of humanity’s relationship with nonhuman animals comes from political theorist Dinesh Wadiwel, who describes it as a state of war — not a metaphorical war, but a literal one, in which we are the aggressors. If you were an alien who knew nothing about our species, you might expect a civilization that does what we do to other creatures to be filled with people who hate animals and like to make them suffer.  And yet the vast majority of people care deeply about animals and hate to see them mistreated, so much so that the meat industry in the US and elsewhere has pushed to make it a crime to film conditions inside factory farms. Because we cannot be the morally righteous species we think we are while truly seeing what we have made.  This contradictory truth about our species may be our greatest refuge against despair. We do have profound capacities for compassion and moral courage, and so many of us already do know there’s something broken in our relationship with animals. As living standards rise around the world and American-style factory farming proliferates in regions that have long relied on largely plant-based diets, animal and vegan advocacy are on the rise, too.  Everywhere in the world, across not just the Global North but also Latin America, Asia, and Africa, a growing movement of people is recognizing that our treatment of animals is a stain on the human conscience that must be wiped away. One of the greatest moral tests we’ll face over the next century will be whether we can heed these voices and decouple human prosperity from tyranny over animals.   Taking the green pill Several years ago, New York Times journalist and Vox cofounder Ezra Klein coined “taking the green pill”: the experience of waking up to the mass torture of farm animals typically unremarked upon in polite society. And once you awaken, Klein said on a 2018 episode of his podcast, all of a sudden “a world that seems completely normal becomes a horror show.”  Taking the green pill is depressing, socially alienating, and deeply countercultural; those who make the leap often struggle to get their loved ones to see the obvious, all while being told by society that they are actually the weird ones. I’ve been one of these weird people since relatively early in life, and most of my time on Earth has been spent trying to understand why what was scorchingly clear to me remained unthinkable to everyone else.  Why I wrote this Since I made the choice to leave meat behind for ethical reasons more than a decade ago, the factory farm system has only gotten bigger and bigger. That’s one reason why I’ve spent the last several years reporting on meat’s impacts on animals, climate, politics, and culture. In this piece, I wanted to take a step back and think through the depth of the challenge facing the movement against animal exploitation.Have questions, comments, or ideas? Email me: marina@vox.com. Still, over the last few decades, as animal welfare advocacy rapidly expanded and the crime of factory farming penetrated the public consciousness, many of these green-pilled people had cause to hope that we were on the cusp of an animal rights revolution. As a teenager in the late aughts, I became convinced factory farming wouldn’t survive another decade. I’d been educated to believe in the steady clip of social progress, and it was the dawn of Obama’s America, when radically new possibilities felt within reach. It seemed inconceivable that something both so wrong and so unnecessary, and so ultimately ruinous to humanity, could keep operating as the curtain was gradually pulled back. I was far from the only one who thought this way. In college, a prominent animal rights figure told me about a theory that the movement’s ranks would soon grow exponentially, as every vegan in the world influenced a few of their loved ones to stop eating animals, and each one of those then influenced another few, and so on until we reached a critical mass large enough to transform society. If that sounds risible to you, consider how rapidly the world had changed in the half-century before. The very idea that tomorrow could look different from today came from recent experiences of social transformation in the US and around the globe, including decolonization, women’s liberation, gay rights, and the gradual if incomplete lifting of American racial apartheid. Not only has such a transformation for animals failed to materialize, but we may be even further away from it than we were 10 or 20 years ago. For all the awareness raised, US per capita meat consumption sits at record highs, suggesting that we haven’t managed to convince a meaningful share of the public to decrease their intake, let alone go vegetarian or vegan. Worse, Americans are now eating less red meat and a lot more chickens, the most abused animals on the planet, who make up more than 90 percent of the 10 billion animals slaughtered annually in the US. Because they weigh far less than cows or pigs, it takes many more individuals to produce an equivalent amount of meat.  Although we often use “factory farming” as a convenient shorthand for our systematic cruelty to animals, the true problem is much older, and runs far deeper than modern food production. People today often imagine that before industrialization, we used to raise animals the “right way,” conjuring images of Old MacDonald’s farm, where domesticated animals lived in harmony with humans and nature.  Today’s meat industry profits from such powerful cultural associations, slapping pictures of happy animals onto their product labels and ad copy, but these have always been mythologies. Beyond the marketing is the reality that livestock animals have always been property, brought into the world without rights and for human purposes — bred to maximize productivity, mutilated and branded with hot irons, and slaughtered at the time of our choosing.  Long before we had the ability to pack together thousands of animals in industrial sheds, humans wrestled with the horrors of animal exploitation and slaughter. Leo Tolstoy, in his 1891 essay “The First Step” (“Pervaya Stupen”) advocating for a vegetarian diet, wrote about witnessing the killing of farm animals in czarist Russia. He describes a village pig dragged outside for slaughter, the animal’s “human-looking pink body” screaming in a “dreadful voice, resembling the shriek of a man.” After the screams subside and the animal is dead, even the gruff carriage driver accompanying Tolstoy lets out a heavy sigh. “Do people really not have to answer for such things?” he asks.  It would be unwise to judge our ancestors, who lived under far harsher conditions with extraordinarily high mortality rates even among humans, for their treatment of animals. More important is to understand that the human relationship with livestock has always been one of ownership and exploitation, which trumps their inherent needs and desires as living, autonomous creatures. Even on today’s so-called humane farms, animals often endure terrible physical and psychological suffering, as the Atlantic’s Annie Lowrey found in a sprawling investigation into one of the country’s most celebrated organic dairies.  What is distinct about factory farming is how it’s deployed modern agricultural, biomedical, and financial technologies to push the exploitation of animals to astonishing new extremes. Much like technology has given humans the means to wage war against each other at a terrifying scale, it has also supercharged the human war on animals.  Modern farmed animals’ bodies have been hyperoptimized for productivity without regard for welfare, so long as their productive capacity is unharmed. The livestock industry, with the aid of the US government, is continually testing how far animals can be pushed to yield more meat and more offspring. Chickens farmed for meat grow so large so fast that they live in chronic pain, and their legs often can’t support their weight; egg-laying hens produce 20 times more eggs than their wild-animal counterparts; dairy cows now make about three times more milk than they did 60 years ago; mother pigs have been bred to give birth to ever-more piglets in each litter, resulting in frail, suffering runts. “It appears to be near-impossible in the industry to encounter a conceptual or ethical limit proposed for sows’ biological reproductive capacity,” Tufts anthropologist Alex Blanchette wrote in his 2020 book Porkopolis.   And, of course, there are the numbers. Factory farming’s defining quality is sheer quantity, as my friend and philosopher John Sanbonmatsu put it. It’s reengineered the makeup of life on Earth to such an extent that, Kyle Fish argued in a post on the Effective Altruism forum last year, “the entire good of humanity may be outweighed by the cumulative suffering of farmed animals, with total animal suffering growing faster than human wellbeing is increasing.” It’s a provocative claim, but you don’t have to be a utilitarian to see the insight in it.   It will be a long fight from here The solution is right in front of us — and need not even require any new technology — if we want it.  Today’s animal movement is vibrant, intrepid, and intellectually, politically, and racially diverse. More people than ever from varying backgrounds are working to dismantle animal exploitation — lawyers, veterinarians, climate advocates, conservationists, scientists, philosophers,  physicians, chefs, Hollywood stars, athletes, journalists, and old-fashioned, troublemaking activists. The cause is compelling enough to transcend the left-right binary, capacious enough to welcome everyone from leftists and progressives to neoliberals and movement conservatives.  Because animal rights has never been invited into the political mainstream, as other social causes eventually were, it maintains a lively spirit of experimentation, throwing creative ideas at the wall to see what sticks. One of the movement’s most exhilarating triumphs in recent memory took place in October 2022, when two activists with the group Direct Action Everywhere (DxE), Wayne Hsiung and Paul Picklesimer, were acquitted of felony charges by a jury in a deep-red county of Utah for entering an enormous Smithfield Foods factory farm and rescuing two sick, suffering baby pigs.  “The jury made the right choice,” Hsiung later wrote in the New York Times. “Our society eventually will, too.” Some jurors later reported being transformed by the experience. It was a stunning David and Goliath outcome, showing that even the most radical advocates of animal liberation, when given a chance to explain themselves, could win over unexpected audiences.  These moments are electrifying, yet getting them to enter public awareness, beyond a narrow sliver of animal rights obsessives, can feel like moving mountains. At the end of the day, the meat industry’s kill count continues to surge.   But there’s another way of looking at it: As my colleague Kenny Torrella points out, for a movement with a relatively tiny budget (by one account, smaller than that of the Metropolitan Museum of Art), farm animal advocates have achieved extraordinary things. They’ve managed to pass laws banning cruel factory farm practices in upward of a dozen states and convert a sizable share of the egg market to cage-free, freeing millions of birds from the most extreme forms of confinement. They’ve trounced meat industry giants in courtrooms, from DxE’s criminal acquittals to the Supreme Court’s vindication of Proposition 12 — despite the fierce opposition of the pork industry. A landmark California law, Proposition 12 bans pork produced with gestation crates, tiny cages that trap pigs in spaces barely larger than their bodies. Imagine how much more the movement could do if it had even one percent more resources, or had the buy-in of movements that should be natural allies.  One parallel cause is especially important here: the climate movement, until recently politically marginal like animal rights, but now squarely within mainstream policymaking. Animal and climate advocacy, at least in theory, share an enormous amount of common ground: The scientific consensus calling for meat reduction to stay below warming targets is as unambiguous as the consensus on climate change itself.  Yet dietary change remains a political lightning rod, and US climate advocates tend to shy away from it. Building meaningful partnerships between the animal and environmental camps may be the clearest route to changing that, for the sake of both animals and our future on Earth.  But there’s danger for farmed animals here, too: Because beef is far worse for the climate than other meats, particularly poultry, a focus on reducing emissions from livestock could end up replacing cows with billions more chickens (for this reason, some have argued against climate-based animal advocacy altogether). The US has already been on that path for decades; some global leaders, unconvinced that dietary change is possible, see it as a pragmatic climate solution.   Some climate experts are proving depressingly willing to sacrifice animals to shave off carbon emissions, calling for the “sustainable intensification” of animal agriculture — a disputed concept but one that can often mean, as my colleague Kenny Torrella points out, ramping up factory farmification and optimizing animals’ genes for productivity in an effort to get more meat for fewer emissions, much the same process that gave us today’s Frankenchickens. To prevent these outcomes, animal advocates will have to learn to work with and persuade those who don’t see the welfare of farmed animals as a priority.  For the green-pilled, our society’s collective unwillingness to see that we could simply stop eating animals, or at least so many of them, and all be better off for it can be exasperating. Animal rights poses a fundamental challenge to foundational aspects of human civilization — not just what we eat but also things like our presumed right to breed, cage, and kill animals for scientific experiments. It challenges our very place on the planet. Peter Singer, the philosopher whose work is sometimes credited with helping launch the modern animal rights movement, was absolutely right when he argued that there can be no rational justification for what we do to nonhuman animals; we’re not as special among species as we think we are. Only a tiny movement of iconoclasts has been willing to face up to this.  It would be easy to descend into fatalism, a kind of anthro-pessimism, about the possibility of things getting better as long as humans dominate the planet. Certainly the numbers look that way. But this may stem, paradoxically, from an excess of optimism: We expect change to come fast. We may, instead, need to learn to see the animal liberation movement as part of a very early vanguard — akin to Mary Wollstonecraft, a forebear to modern feminism who was considered a radical thinker in the 18th century for arguing that women were capable of reason and full citizenship, or Benjamin Lay, the militant early 18th-century Quaker abolitionist (and animal rights advocate) who gave hell to his slave-owning co-religionists. Today’s animal activists, too, are laying the foundation for a future that people alive today may never see — a humbling realization but also, perhaps, an empowering one.  Progress is never guaranteed, but the future will always look different from the present, and we as a species have often surprised ourselves with our capacity to change our values, cultures, and economic systems. For example, although we might expect moral change to precede behavioral change, it may work the other way around. Our brains are, famously, self-justification machines, so if climate imperatives can eventually push us to eat less meat, that might start to shift values in favor of animal rights, as people no longer need to search for rationalizations for eating factory farmed animals. We might also yet see a breakthrough in food technology, like slaughter-free meat, that can smooth the path. Giving up, in any case, is not an option.  For the billions upon billions of present and future animals who’ll be forced to suffer in a pointlessly cruel system of our making, that’s a cold comfort. For the rest of us, there is work to do. 

If you can stand to think about it long enough, the problem becomes paralyzing.

It will be a long fight from here

The solution is right in front of us — and need not even require any new technology — if we want it. 

Today’s animal movement is vibrant, intrepid, and intellectually, politically, and racially diverse. More people than ever from varying backgrounds are working to dismantle animal exploitation — lawyers, veterinarians, climate advocates, conservationists, scientists, philosophers,  physicians, chefs, Hollywood stars, athletes, journalists, and old-fashioned, troublemaking activists.

Progress is never guaranteed, but the future will always look different from the present, and we as a species have often surprised ourselves with our capacity to change our values, cultures, and economic systems. For example, although we might expect moral change to precede behavioral change, it may work the other way around. Our brains are, famously, self-justification machines, so if climate imperatives can eventually push us to eat less meat, that might start to shift values in favor of animal rights, as people no longer need to search for rationalizations for eating factory farmed animals. We might also yet see a breakthrough in food technology, like slaughter-free meat, that can smooth the path. Giving up, in any case, is not an option. 

For the billions upon billions of present and future animals who’ll be forced to suffer in a pointlessly cruel system of our making, that’s a cold comfort. For the rest of us, there is work to do.

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.
