Amina Martin rehabilitates pigeons and other birds in a small apartment in Bay Ridge, Brooklyn. | Benji Jones/Vox In NYC, many wildlife rehabbers see pests as part of a thriving urban ecosystem. BAY RIDGE, New York City — One sunny afternoon in March, Amina Martin answered the phone in her small Brooklyn apartment. On the line was a taxi driver, who told her he had a pigeon in his backseat and was heading her way. The bird needed Martin’s help. In New York, you never really know who your neighbors are. You might worry they have bedbugs or hoard cats. Maybe they’re celebrities. Or perhaps their apartments are filled with opossums, squirrels, and birds, all rescued from the streets of NYC. Martin, a Russian immigrant, is that neighbor. Her studio is full of pigeons, morning doves, and a handful of other stray birds including an African gray parrot named Elmoar. The animals are in cages that line the wall in front of her bed. Some of the birds have broken wings, trouble walking, or are partially blind. Others are abandoned pets with little chance of survival in the wild. At least twice a week, Martin lets each pigeon out of its cage to fly around her apartment. It was loud in her apartment when I met her that afternoon — a racket of coos and cheeps and the occasional interjection from Elmoar. “He’s teaching me English,” Martin jokes, adding that he says words like “whatsoever” that she’s had to look up. Martin let out a couple of pigeons who flew around her apartment, including her favorite bird, named Anfisa. The animal had ombré gray plumage with pops of iridescent purple and green (i.e., she looked like a pigeon). “She’s in love with my husband,” Martin told me. “She lays eggs on his pillow because she thinks he’s her boyfriend.” Martin is among a small number of people across the New York City boroughs who rehabilitate injured creatures that many other people label as pests. The driver who called Martin had brought birds to her before; an acquaintance of hers finds injured pigeons on the street and calls the same one or two taxi drivers to deliver them. (Sending birds via taxi? “It’s a common thing,” Martin says.) Over several weeks this spring, I met more than a dozen licensed wildlife rehabilitators (aka, “rehabbers”) in New York. Many of them, like Martin, care for animals at home, turning their living rooms into makeshift wildlife hospitals. I visited a duplex in Staten Island full of squirrels and rats; a room in the Upper West Side with a box of baby opossums; and a small park on Roosevelt Island with injured Canada geese, adult opossums, and house cats, all living together and in some cases sleeping side-by-side. One rehabber in Manhattan told me she converted her balcony into an atrium for injured birds. Top left: A four-week-old opossum getting ready to be fed. Top right: Rehabber Amanda Lullo holds a friendly wild rat she’s caring for. Bottom left: A young squirrel sucking down animal infant formula. Bottom right: A baby opossum in a furry sack. New York’s rehabber community is small; the opossum, pigeon, and squirrel people tend to know each other. Some of them, like Martin, document their work on Instagram, amassing a hefty following. But many of them operate under the radar to avoid unwanted attention from the Department of Health, or their landlords. (A bedroom full of squirrels is typically beyond a building’s pet policy.) You might be thinking: What are they thinking? People are commonly disgusted by the animals that have adapted to live alongside us — to eat our garbage, to sleep in our streets. We typically want them out of our homes, not in. Wild animals, no matter the species, can also be noisy, dirty, and sometimes diseased. (One of Martin’s pigeons pooped on her bed, and of course, I sat right in it.) “I’m so broke right now. All of my money goes to the animals.” What’s even more puzzling is that most of these rehabbers work for free, often around the clock, to care for these animals until they’ve healed. They often spend what little money they have on feed, specialized equipment including syringes and IV bags, and medicine. One rehabber told me that she can’t afford to buy herself new clothes. “I’m so broke right now,” they said. “All of my money goes to the animals.” As I spent time with rehabbers, I began to see their perspective. They view these species not as pests but as part of nature — as part of the New York City ecosystem. As part of their home. These animals belong here, rehabbers told me, just as much as we do. And they don’t deserve the harm that humans so often inflict on them, whether deliberately or not. By showing these animals some respect and helping them survive, rehabbers appear to feel more connected with their environment, with what they see as nature. That enriches their lives and makes them feel less alone. Maybe they’re onto something. A common sight in NYC and a food source for many of its critters: A pile of trash on the street, shot in the East Village. Nearly every inch of New York, the nation’s largest and densest city, has been transformed by humans. Even its parks are largely artificial: The ponds, streams, and waterfalls in Manhattan’s Central Park, for example, are fed by city drinking water. Yet the city is brimming with non-human life. On a warm evening in March, I strolled through Central Park and saw a few dozen raccoons, several of which were eating a large pile of spaghetti. I put a motion-sensing camera in Brooklyn’s Green-Wood Cemetery (where conductor and pianist Leonard Bernstein, among other icons, is buried) and it captured videos of groundhogs, skunks, opossums, and stray cats. The city’s ponds are full of turtles. There are even seahorses in the Hudson River, once a dumping ground for chemicals and dead bodies. “I see nature everywhere in New York City,” says Dustin Partridge, director of conservation and science at NYC Audubon, one of the leading environmental groups in the city. Raccoons, some of the most common wild animals in NYC, prowl Central Park after dark. They helped themselves to a large pile of pasta someone had dumped. Some of the city’s animals are native to the region and have found ways to survive, even as developers chop up and pave over their habitats. Staten Island is still home to a rare amphibian called the Atlantic coast leopard frog, once common in Brooklyn, Queens, and Long Island. Around full and new moons in late spring, horseshoe crabs — ancient creatures that have been on Earth for hundreds of millions of years — still come ashore on NYC beaches to find mates and lay eggs. Islands in the harbor are home to loads of water birds like black-crowned night herons and egrets. Many other species, meanwhile, are here in New York, in large part, because of us — or because they tolerate us. The wild ancestors of pigeons, which are domestic birds, lived on cliffsides. These days they’re happy to nest on the sides of buildings. Of the several million tons of trash the city produces each year, the occasional overflowing receptacle or torn trash bag provides ample food for rats and raccoons. Images captured by a motion-sensing camera installed on a trail in Green-Wood Cemetery, in South Brooklyn. These furry city slickers don’t fit neatly into any of our categories for animals, says Seth Magle, who runs the Urban Wildlife Institute at the Lincoln Park Zoo in Chicago. They exist somewhere between domesticated pets, like cats and dogs, and wildlife, like wolves and bears. “They occupy this invisible space in peoples’ heads,” Magle told me. And that many of New York’s most common critters are not native to the region further complicates our feelings toward them. The pigeons evolved in Europe and North Africa, and the rats are from Asia. House sparrows and European starlings are native to the eastern hemisphere. Even the squirrels, which technically are native to New York, were artificially introduced to the city in the 1870s, after hunting and deforestation wiped out their resident population. The plight of these common city animals is that they are so widely unloved. We treat them as if they don’t belong here, in our home. Even if they’re native to New York, we don’t want them in our city. Cities are for humans. Distant forests — environments that we can visit at our leisure, on our own terms — are for them. In Green-Wood Cemetery, a colony of monk parakeets, birds native to South America, have built a giant nest atop the main gate. In reality, we’ve already taken most of the planet for ourselves. Only a fraction of those distant forests remain. That’s why an estimated one million plant and animal species are now slipping toward extinction. The animals that are plentiful in cities like New York, these “pests,” are “winners on a planet full of loss,” as environmental author Bethany Brookshire wrote in her 2022 book Pests. Their abundance is, in a way, a success story. To be clear, building a home for humans in New York has heavily degraded the natural ecosystem; the city has, for example, lost 99 percent of its freshwater wetlands. From another perspective, however, cities like New York have created a new ecosystem — a new web of life. On any given day in late spring or summer, Arina Hinzen might be wearing a scarf around her neck full of baby opossums. Just as these marsupials cling to their mothers in the wild, the babies — some no larger than a ping-pong ball — cling to the fabric, like an animal print come to life. The animals seem to enjoy riding with Hinzen as she moves about. If they smell something delicious, she told me, the babies poke their snouts out for a whiff. Hinzen, a licensed rehabber who runs a wildlife welfare group in the city called Urban Wildlife Alliance, is what you might call Manhattan’s premier opossum godmother. In the last decade, the German native has rehabbed roughly 1,500 animals, including hundreds of baby opossums, she said. A single female opossum can give birth to more than a dozen infants, each no larger than a jelly bean. If just one mother gets hit by a car, as is common in NYC, they’ll all be in need of life support. Often, when people find them, Hinzen is who they call. Arina Hinzen, one of NYC’s most trusted opossum rehabbers, feeds a four-week-old baby by inserting a thin tube into its stomach. Raising baby opossums — which differ from possums, an entirely different marsupial native to Australia — was not always her life. Nor has it been her most unusual vocation. As a young adult in Germany, Hinzen spent more than a decade judging skydiving competitions. Parachuters would hurl themselves from planes, sometimes do tricks in the air, and then try to land on a target. (She, herself, has jumped from a plane close to 500 times.) From there, Hinzen pursued a career in viticulture, got married, and built a wine importing company in NYC with her then-husband. Years later — now more than a decade ago — Hinzen’s marriage and her company fell apart, she told me, as we shared a bottle of wine on a bench in Central Park. Her world crumbled. It was around that time, Hinzen says, that she came across an injured pigeon in the Upper West Side. The bird was puffed up on the steps of a church and looked emaciated. Hinzen felt an urge to help. “It seemed like she had already checked out and given up on life,” Hinzen told me. “I think that’s what drew my attention, because I felt almost the same.” Hinzen prepares a baby opossum for feeding. She uses a specialized animal infant formula. At this age, Hinzen feeds the baby opossums five times a day. Each feeding takes about an hour and a half, she told me. Hinzen brought home the debilitated bird and with help from a local rehab center, nursed it back to health. She released the pigeon — Richard — a few months later. “To see that you can bring something back from the edge of death that has lost all hope ignited my passion,” she told me. Hinzen, a Buddhist, rescued more pigeons in the months that followed, eventually graduating to infant squirrels and opossums. They have become her specialty. In the spring, Hinzen told me that she might have 40 babies at one time and be tending to them 18 or 19 hours a day. “It has completely taken over my life,” she says. In these creatures, Hinzen, like other rehabbers, sees something that many of us don’t: something relatable. “I’m absolutely convinced that these animals have an emotional life,” she says. “At the end of the day, all they want is to live, to bring up their families, and to eat. They want the same as we want.” “At the end of the day, all they want is to live. They want the same as we want.” Feeling a connection with these animals, and compassion for them, has enriched her life in the city, she says. Even just noticing them more — their quirky behaviors, their bizarre features — can inspire awe, she says. “We are conditioned to see ourselves as different from other living beings,” Hinzen told me. “We have lost a feeling of connection to them. We have forgotten that we are part of nature and part of an ecosystem as much as they are.” Amanda Lullo, a rehabber in Staten Island, prepares to feed a handful of orphaned baby squirrels. Amanda Lullo, a squirrel rehabber on Staten Island, echoes some of that thinking. “Everything serves a purpose,” she told me. Rats are “nature’s garbage disposals,” she says, and squirrels are “nature’s gardeners,” since they bury seeds that grow into trees — at least when they don’t retrieve them to eat later. “We need these animals,” she says. I visited Lullo’s home on two separate occasions this spring. It’s a modest duplex that looks pretty ordinary. Until you walk inside. About two dozen cages, filled with squirrels, rats, and a couple of ferrets, were stacked up against the walls. An IV hung from the ceiling. A handful of pet cats and a rescued pit bull roamed around — and, in one case, slept on top of — the cages, remarkably disinterested in the animals inside. As we walked around her home, Lullo, who grew up in Brooklyn, introduced me to the animals. There was Pistachio, a.k.a. Fat Boy, a pudgy squirrel who fell from a tree as a baby. The fall broke his arm and cracked his tooth, she said, as the animal (now mostly healed) crawled around Lullo’s body. Lullo also showed me several baby squirrels including a five-week-old; she feeds them a special animal infant formula with a dash of heavy cream using a syringe. Lullo feeds a blueberry to one of the young squirrels she’s caring for. An array of clean syringes that Lullo uses to feed the baby squirrels. I also met a couple of wild rats, most named after fruits, including Strawberry and Blueberry. (Lullo raised them from infancy. Sometimes when people kill rats they find out that they have babies, Lullo said. They feel bad and call a rehabber.) Though common, these animals are deserving of care, Lullo says. “Humans kill and destroy everything they touch,” she says. The animals of New York City, she explains, are mostly harmless and they just want to live. Once rehabbers start caring for injured wildlife, they also just find it hard to stop. These people see critters in need everywhere. Rehabber Mary Beth Artz throws food pellets into a lake in Brooklyn’s Prospect Park to try and attract a domestic duck in need of rescue. “Once you know, you can’t unknow,” said Mary Beth Artz, a rehabber and stage actor who rescues ducks and other birds from Prospect Park in Brooklyn. (She’s currently rehabbing a jumbo Pekin named Freddie at her home. Last fall, the duck, which may have been purchased as a pet, was abandoned in a Queens parking lot, she said.) “I say it all the time — ‘I’m not going to do this anymore’ — but then something else happens,” Artz told me one afternoon in Prospect Park, while she was trying to rescue a domestic khaki Campbell duck that was dumped in the lake. “If we don’t do it, who’s going to do it?” An uncomfortable answer to that question might be, well, perhaps no one should. Indeed, there are some good reasons to limit the numbers of certain urban critters. Raccoons and skunks can carry rabies and other diseases. Rodent infestations, meanwhile, are particularly harmful to people experiencing homelessness, Brookshire writes in Pests. Their constant squeaks can make it impossible to sleep. (I couldn’t find anyone, aside from Lullo, who is rehabbing rats in the city. Lullo doesn’t plan to release them. Similarly, rehabbers seldom rescue raccoons, which require a more advanced license.) “Disease is always a risk with wildlife,” said Myles Davis, a city wildlife expert who manages NYC Audubon’s green infrastructure program. (That said, “You are never at risk of getting rabies from a raccoon,” he added, if you only observe it from afar.) A red-tailed hawk in Green-Wood Cemetery rips apart a pigeon, an abundant food source in NYC. An overabundance of these animals can also interfere with efforts to protect the city’s rarer species — stoking longstanding tensions between animal welfare and conservation. Pigeons may be an important food source for native raptors, including the once near-extinct peregrine falcon, but raccoons and opossums eat the eggs and chicks of native birds, according to Partridge. This complicates the question of what belongs in an urbanized environment. I raised these tensions with Catherine Quayle, a spokesperson for the Wild Bird Fund, the city’s most well-known and largest rehab center, mostly focused on birds. “Wildlife rehab is not a practice of conservation,” she told me. “It’s a practice of compassion.” To tell the public that some animals matter and other ones don’t “defeats our mission,” she said, “which is to teach people about wildlife.” As Quayle sees it, showing compassion for any wild creature, whether it’s a pigeon pecking at a slice of pizza or a songbird flying through during spring migration, can engender more respect for the wild world at large. It can help erode the dividing line between humans and pests, ultimately making us better stewards of our environment. We really need to be better stewards. Many features of the NYC built environment harm all animals, rare and common alike. Building windows are too reflective, causing birds to crash into them. Rat poison not only makes rodents suffer but harms the rodent-eating raptors. Flaco, a famous owl that escaped last year from the Central Park Zoo (with the help of a miscreant), died recently after colliding with a building. An autopsy revealed that he had four kinds of rat poison in his body (as well as a form of herpes found in pigeons). This doesn’t mean we should throw up our hands and welcome these animals in with open arms. But maybe — just maybe — NYC could find a way to, you know, not place trash on the street in flimsy plastic bags. (The city says it’s working on it.) You may think urban animals are gross, but we are the ones filling the city with trash. After warm weekend days, trash cans in Prospect Park are overflowing with animal-attracting garbage. Two of NYC’s most common (and most reviled) wild creatures. I still struggle with my own feelings toward these creatures. I happen to live on a rat-ridden street in Brooklyn. On a walk the other night, my dog lunged for a stray cat which then lunged for a large rat (and successfully snatched it). I’ve dealt with mice and bugs in my apartment. Last fall, I had to move because of a roach infestation. If this is the New York City ecosystem, I’m not sure how close to nature I want to be. What is clear to me is the simple power of connecting with animals as individuals, of pausing even briefly to observe their lives. Watching house sparrows bathe in a grimy fountain or squirrels chase each other around a tree can, I’d argue, inspire awe. And to see them suffering can be incredibly painful. That much was clear to me back in Bay Ridge, where I was waiting with Martin, the bird rehabber, for the pigeon delivery. A white SUV pulled up, and the driver retrieved a cat carrier from the backseat. Martin took the carrier and set it down on a nearby bench. The pigeon inside was still and its eyes glossy; I could see its breast faintly rise and fall. It wasn’t doing well, Martin said. The bird was about to die. We sat there in silence, Martin lightly petting the pigeon’s back. And a moment later, the animal was completely still. It had passed away, Martin told me. “You never get used to it,” she said, quietly. Frankly, I was devastated. I’ve rarely given pigeons much thought, but at that moment — after witnessing life vanish — I was comforted knowing that these birds, and that so many other unloved creatures across the city, have people looking out for them.

In NYC, many wildlife rehabbers see pests as part of a thriving urban ecosystem.

BAY RIDGE, New York City — One sunny afternoon in March, Amina Martin answered the phone in her small Brooklyn apartment. On the line was a taxi driver, who told her he had a pigeon in his backseat and was heading her way. The bird needed Martin’s help.

In New York, you never really know who your neighbors are. You might worry they have bedbugs or hoard cats. Maybe they’re celebrities. Or perhaps their apartments are filled with opossums, squirrels, and birds, all rescued from the streets of NYC.

Martin, a Russian immigrant, is that neighbor.

Her studio is full of pigeons, morning doves, and a handful of other stray birds including an African gray parrot named Elmoar. The animals are in cages that line the wall in front of her bed. Some of the birds have broken wings, trouble walking, or are partially blind. Others are abandoned pets with little chance of survival in the wild.

At least twice a week, Martin lets each pigeon out of its cage to fly around her apartment.

It was loud in her apartment when I met her that afternoon — a racket of coos and cheeps and the occasional interjection from Elmoar. “He’s teaching me English,” Martin jokes, adding that he says words like “whatsoever” that she’s had to look up.

Martin let out a couple of pigeons who flew around her apartment, including her favorite bird, named Anfisa. The animal had ombré gray plumage with pops of iridescent purple and green (i.e., she looked like a pigeon). “She’s in love with my husband,” Martin told me. “She lays eggs on his pillow because she thinks he’s her boyfriend.”

Martin is among a small number of people across the New York City boroughs who rehabilitate injured creatures that many other people label as pests. The driver who called Martin had brought birds to her before; an acquaintance of hers finds injured pigeons on the street and calls the same one or two taxi drivers to deliver them. (Sending birds via taxi? “It’s a common thing,” Martin says.)

Over several weeks this spring, I met more than a dozen licensed wildlife rehabilitators (aka, “rehabbers”) in New York. Many of them, like Martin, care for animals at home, turning their living rooms into makeshift wildlife hospitals. I visited a duplex in Staten Island full of squirrels and rats; a room in the Upper West Side with a box of baby opossums; and a small park on Roosevelt Island with injured Canada geese, adult opossums, and house cats, all living together and in some cases sleeping side-by-side. One rehabber in Manhattan told me she converted her balcony into an atrium for injured birds.

New York’s rehabber community is small; the opossum, pigeon, and squirrel people tend to know each other. Some of them, like Martin, document their work on Instagram, amassing a hefty following. But many of them operate under the radar to avoid unwanted attention from the Department of Health, or their landlords. (A bedroom full of squirrels is typically beyond a building’s pet policy.)

You might be thinking: What are they thinking? People are commonly disgusted by the animals that have adapted to live alongside us — to eat our garbage, to sleep in our streets. We typically want them out of our homes, not in. Wild animals, no matter the species, can also be noisy, dirty, and sometimes diseased. (One of Martin’s pigeons pooped on her bed, and of course, I sat right in it.)

What’s even more puzzling is that most of these rehabbers work for free, often around the clock, to care for these animals until they’ve healed. They often spend what little money they have on feed, specialized equipment including syringes and IV bags, and medicine. One rehabber told me that she can’t afford to buy herself new clothes. “I’m so broke right now,” they said. “All of my money goes to the animals.”

As I spent time with rehabbers, I began to see their perspective. They view these species not as pests but as part of nature — as part of the New York City ecosystem. As part of their home. These animals belong here, rehabbers told me, just as much as we do. And they don’t deserve the harm that humans so often inflict on them, whether deliberately or not.

By showing these animals some respect and helping them survive, rehabbers appear to feel more connected with their environment, with what they see as nature. That enriches their lives and makes them feel less alone.

Maybe they’re onto something.

Nearly every inch of New York, the nation’s largest and densest city, has been transformed by humans. Even its parks are largely artificial: The ponds, streams, and waterfalls in Manhattan’s Central Park, for example, are fed by city drinking water.

Yet the city is brimming with non-human life.

On a warm evening in March, I strolled through Central Park and saw a few dozen raccoons, several of which were eating a large pile of spaghetti. I put a motion-sensing camera in Brooklyn’s Green-Wood Cemetery (where conductor and pianist Leonard Bernstein, among other icons, is buried) and it captured videos of groundhogs, skunks, opossums, and stray cats. The city’s ponds are full of turtles. There are even seahorses in the Hudson River, once a dumping ground for chemicals and dead bodies.

“I see nature everywhere in New York City,” says Dustin Partridge, director of conservation and science at NYC Audubon, one of the leading environmental groups in the city.

Some of the city’s animals are native to the region and have found ways to survive, even as developers chop up and pave over their habitats.

These days they’re happy to nest on the sides of buildings. Of the several million tons of trash the city produces each year, the occasional overflowing receptacle or torn trash bag provides ample food for rats and raccoons.

The plight of these common city animals is that they are so widely unloved. We treat them as if they don’t belong here, in our home. Even if they’re native to New York, we don’t want them in our city. Cities are for humans. Distant forests — environments that we can visit at our leisure, on our own terms — are for them.

In these creatures, Hinzen, like other rehabbers, sees something that many of us don’t: something relatable. “I’m absolutely convinced that these animals have an emotional life,” she says. “At the end of the day, all they want is to live, to bring up their families, and to eat. They want the same as we want.”

Feeling a connection with these animals, and compassion for them, has enriched her life in the city, she says. Even just noticing them more — their quirky behaviors, their bizarre features — can inspire awe, she says.

“We are conditioned to see ourselves as different from other living beings,” Hinzen told me. “We have lost a feeling of connection to them. We have forgotten that we are part of nature and part of an ecosystem as much as they are.”

Amanda Lullo, a squirrel rehabber on Staten Island, echoes some of that thinking. “Everything serves a purpose,” she told me. Rats are “nature’s garbage disposals,” she says, and squirrels are “nature’s gardeners,” since they bury seeds that grow into trees — at least when they don’t retrieve them to eat later. “We need these animals,” she says.

I visited Lullo’s home on two separate occasions this spring. It’s a modest duplex that looks pretty ordinary. Until you walk inside. About two dozen cages, filled with squirrels, rats, and a couple of ferrets, were stacked up against the walls. An IV hung from the ceiling. A handful of pet cats and a rescued pit bull roamed around — and, in one case, slept on top of — the cages, remarkably disinterested in the animals inside.

As we walked around her home, Lullo, who grew up in Brooklyn, introduced me to the animals. There was Pistachio, a.k.a. Fat Boy, a pudgy squirrel who fell from a tree as a baby. The fall broke his arm and cracked his tooth, she said, as the animal (now mostly healed) crawled around Lullo’s body. Lullo also showed me several baby squirrels including a five-week-old; she feeds them a special animal infant formula with a dash of heavy cream using a syringe.

I also met a couple of wild rats, most named after fruits, including Strawberry and Blueberry. (Lullo raised them from infancy. Sometimes when people kill rats they find out that they have babies, Lullo said. They feel bad and call a rehabber.)

Though common, these animals are deserving of care, Lullo says. “Humans kill and destroy everything they touch,” she says. The animals of New York City, she explains, are mostly harmless and they just want to live.

Once rehabbers start caring for injured wildlife, they also just find it hard to stop. These people see critters in need everywhere.

“Once you know, you can’t unknow,” said Mary Beth Artz, a rehabber and stage actor who rescues ducks and other birds from Prospect Park in Brooklyn. (She’s currently rehabbing a jumbo Pekin named Freddie at her home. Last fall, the duck, which may have been purchased as a pet, was abandoned in a Queens parking lot, she said.)

“I say it all the time — ‘I’m not going to do this anymore’ — but then something else happens,” Artz told me one afternoon in Prospect Park, while she was trying to rescue a domestic khaki Campbell duck that was dumped in the lake.

“If we don’t do it, who’s going to do it?”


An uncomfortable answer to that question might be, well, perhaps no one should. Indeed, there are some good reasons to limit the numbers of certain urban critters.

Raccoons and skunks can carry rabies and other diseases. Rodent infestations, meanwhile, are particularly harmful to people experiencing homelessness, Brookshire writes in Pests. Their constant squeaks can make it impossible to sleep. (I couldn’t find anyone, aside from Lullo, who is rehabbing rats in the city. Lullo doesn’t plan to release them. Similarly, rehabbers seldom rescue raccoons, which require a more advanced license.)

“Disease is always a risk with wildlife,” said Myles Davis, a city wildlife expert who manages NYC Audubon’s green infrastructure program. (That said, “You are never at risk of getting rabies from a raccoon,” he added, if you only observe it from afar.)

A red-tailed hawk in Green-Wood Cemetery rips apart a pigeon, an abundant food source in NYC.

An overabundance of these animals can also interfere with efforts to protect the city’s rarer species — stoking longstanding tensions between animal welfare and conservation. Pigeons may be an important food source for native raptors, including the once near-extinct peregrine falcon, but raccoons and opossums eat the eggs and chicks of native birds, according to Partridge. This complicates the question of what belongs in an urbanized environment.

I raised these tensions with Catherine Quayle, a spokesperson for the Wild Bird Fund, the city’s most well-known and largest rehab center, mostly focused on birds. “Wildlife rehab is not a practice of conservation,” she told me. “It’s a practice of compassion.” To tell the public that some animals matter and other ones don’t “defeats our mission,” she said, “which is to teach people about wildlife.”

As Quayle sees it, showing compassion for any wild creature, whether it’s a pigeon pecking at a slice of pizza or a songbird flying through during spring migration, can engender more respect for the wild world at large. It can help erode the dividing line between humans and pests, ultimately making us better stewards of our environment.

We really need to be better stewards. Many features of the NYC built environment harm all animals, rare and common alike. Building windows are too reflective, causing birds to crash into them. Rat poison not only makes rodents suffer but harms the rodent-eating raptors. Flaco, a famous owl that escaped last year from the Central Park Zoo (with the help of a miscreant), died recently after colliding with a building. An autopsy revealed that he had four kinds of rat poison in his body (as well as a form of herpes found in pigeons).

This doesn’t mean we should throw up our hands and welcome these animals in with open arms. But maybe — just maybe — NYC could find a way to, you know, not place trash on the street in flimsy plastic bags. (The city says it’s working on it.) You may think urban animals are gross, but we are the ones filling the city with trash.

After warm weekend days, trash cans in Prospect Park are overflowing with animal-attracting garbage.

Two of NYC’s most common (and most reviled) wild creatures.

I still struggle with my own feelings toward these creatures. I happen to live on a rat-ridden street in Brooklyn. On a walk the other night, my dog lunged for a stray cat which then lunged for a large rat (and successfully snatched it). I’ve dealt with mice and bugs in my apartment. Last fall, I had to move because of a roach infestation. If this is the New York City ecosystem, I’m not sure how close to nature I want to be.

What is clear to me is the simple power of connecting with animals as individuals, of pausing even briefly to observe their lives. Watching house sparrows bathe in a grimy fountain or squirrels chase each other around a tree can, I’d argue, inspire awe. And to see them suffering can be incredibly painful.

That much was clear to me back in Bay Ridge, where I was waiting with Martin, the bird rehabber, for the pigeon delivery. A white SUV pulled up, and the driver retrieved a cat carrier from the backseat. Martin took the carrier and set it down on a nearby bench.

The pigeon inside was still and its eyes glossy; I could see its breast faintly rise and fall. It wasn’t doing well, Martin said. The bird was about to die. We sat there in silence, Martin lightly petting the pigeon’s back. And a moment later, the animal was completely still. It had passed away, Martin told me.

“You never get used to it,” she said, quietly.

Frankly, I was devastated. I’ve rarely given pigeons much thought, but at that moment — after witnessing life vanish — I was comforted knowing that these birds, and that so many other unloved creatures across the city, have people looking out for them.

Changes in polar bear DNA that could help the animals adapt to warmer climates have been detected by researchers, in a study thought to be the first time a statistically significant link has been found between rising temperatures and changing DNA in a wild mammal species.Climate breakdown is threatening the survival of polar bears. Two-thirds of them are expected to have disappeared by 2050 as their icy habitat melts and the weather becomes hotter.Now scientists at the University of East Anglia have found that some genes related to heat stress, ageing and metabolism are behaving differently in polar bears living in south-east Greenland, suggesting they may be adjusting to warmer conditions.The researchers analysed blood samples taken from polar bears in two regions of Greenland and compared “jumping genes”: small, mobile pieces of the genome that can influence how other genes work. Scientists looked at the genes in relation to temperatures in the two regions and at the associated changes in gene expression.“DNA is the instruction book inside every cell, guiding how an organism grows and develops,” said the lead researcher, Dr Alice Godden. “By comparing these bears’ active genes to local climate data, we found that rising temperatures appear to be driving a dramatic increase in the activity of jumping genes within the south-east Greenland bears’ DNA.”As local climates and diets evolve as a result of changes in habitat and prey forced by global heating, the genetics of the bears appear to be adapting, with the group of bears in the warmest part of the country showing more changes than the communities farther north. The authors of the study have said these changes could help us understand how polar bears might survive in a warming world, inform understanding of which populations are most at risk and guide future conservation efforts.This is because the findings, published on Friday in the journal Mobile DNA, suggest the genes that are changing play a crucial role in how different polar bear populations are evolving.Godden said: “This finding is important because it shows, for the first time, that a unique group of polar bears in the warmest part of Greenland are using ‘jumping genes’ to rapidly rewrite their own DNA, which might be a desperate survival mechanism against melting sea ice.”Temperatures in north-east Greenland are colder and less variable, while in the south-east there is a much warmer and less icy environment, with steep temperature fluctuations.DNA sequences in animals change over time, but this process can be accelerated by environmental stress such as a rapidly heating climate.There were some interesting DNA changes, such as in areas linked to fat processing, that could help polar bears survive when food is scarce. Bears in warmer regions had more rough, plant-based diets compared with the fatty, seal-based diets of northern bears, and the DNA of south-eastern bears seemed to be adapting to this.Godden said: “We identified several genetic hotspots where these jumping genes were highly active, with some located in the protein-coding regions of the genome, suggesting that the bears are undergoing rapid, fundamental genetic changes as they adapt to their disappearing sea ice habitat.”The next step will be to look at other polar bear populations, of which there are 20 around the world, to see if similar changes are happening to their DNA.This research could help protect the bears from extinction. But the scientists said it was crucial to stop temperature rises accelerating by reducing the burning of fossil fuels.Godden said: “We cannot be complacent, this offers some hope but does not mean that polar bears are at any less risk of extinction. We still need to be doing everything we can to reduce global carbon emissions and slow temperature increases.”

A Deadly Pathogen Decimated Sunflower Sea Stars. Look Inside the Lab Working to Bring Them Back by Freezing and Thawing Their Larvae

For the first time, scientists have cryopreserved and revived the larvae of a sea star species. The breakthrough, made with the giant pink star, gives hope the technique could be repeated to save the imperiled predator

A Deadly Pathogen Decimated Sunflower Sea Stars. Look Inside the Lab Working to Bring Them Back by Freezing and Thawing Their Larvae For the first time, scientists have cryopreserved and revived the larvae of a sea star species. The breakthrough, made with the giant pink star, gives hope the technique could be repeated to save the imperiled predator Juvenile sunflower sea stars at the Sunflower Star Laboratory in Moss Landing, California. At this phase, each is less than an inch wide, but they can grow to be more than three feet across as adults. Avery Schuyler Nunn Key takeaways: Recovering sunflower sea stars by freezing them in time Ravaged by infectious bacteria, sunflower sea stars literally wasted away across the Pacific coast of North America—and their resulting population crash destabilized kelp forest ecosystems. Scientists pioneered a cryopreservation technique on the closely related giant pink star, raising hopes that a bank of frozen sunflower star larvae could one day be thawed in the same way and released into the wild. Along a working California harbor, where gulls wheel over weathered pilings and the old Western Flyer—the ship John Steinbeck once sailed to the Sea of Cortez—sits restored in its berth, researchers buzz about in a modest lab tucked between warehouses and boatyards. Inside, amid the hiss of pumps and the faint smell of brine from seawater tables, a scientist lifts a small vial from a plume of liquid nitrogen, its frosted casing holding the tiniest flicker of hope for a species on the brink. Each of the 18 vials contains between 500 and 700 larval giant pink sea stars. At this stage, they are tiny specks suspended in seawater, invisible to the naked eye. These particular larvae have been cryopreserved and stored at roughly minus 180 degrees Celsius since March. At the Sunflower Star Laboratory (SSL) in Moss Landing, California, scientists thawed the larval pink sea stars and coaxed them to successfully develop into juveniles this summer—a first for any sea star species. In October, the scientists thawed another batch of larvae from the same cohort to test larval growth and survival under different freezing conditions and thawing protocols. The breakthrough, however, isn’t really about the giant pink star, a species that’s common in the wild. Instead, these larvae serve as a crucial stand-in for the far more imperiled sunflower sea star (Pycnopodia helianthoides)—a vanishing species for which larvae are precious, limited and increasingly difficult to obtain. Perfecting cryopreservation methods on pink stars—ensuring they can survive freezing, resume feeding and grow into juveniles—lays the scientific groundwork for facilitating a return of Pycnopodia. The contents of a thawed vial are placed under a microscope to assess viability of the larvae. Avery Schuyler Nunn The discovery arrives at a precarious time, as sunflower stars have disappeared at a pace rarely seen in marine ecosystems. As a mysterious pathogen ravaged their population along the western shores of North America beginning in 2013, the creatures collapsed from an estimated six billion individuals to functional extinction in parts of their range—all within just a few years. Their loss left kelp forests with dramatically fewer predators, destabilizing ecosystems across the Pacific coast and allowing urchins to proliferate and graze formerly lush underwater canopies into barren rock. Now, scientists hope that “freezing” their larvae will offer a new avenue for bringing the species back. “Cryopreservation is particularly important on the population level when thinking about recovery for this endangered species, because it had major population losses,” says Marissa Baskett, an environmental scientist at the University of California, Davis, who was not involved in the project. The process lets scientists preserve the sea stars’ existing genetic diversity for future reintroduction to the wild, she adds. “Especially given the uncertainty about different disease outbreaks, having that stock to return to is incredibly valuable.” A mysterious and “complete collapse” Sunflower sea stars have long lived in abundance up and down the rugged Pacific coast—from Alaskan archipelagoes to Baja California. The 24-limbed echinoderms sprawled across the seafloor in shades of ochre, crimson and violet. Among the fastest-moving and largest of all sea stars—capable of stretching nearly three feet across—these radiant predators coursed through kelp forests, voraciously hunting purple sea urchins and preventing them from over-grazing on the holdfasts that root towering golden canopies of kelp. An adult sunflower sea star has 24 limbs and can be more than three feet wide. This one was photographed off Point Dume State Beach near Los Angeles. Brent Durand via Getty Images “In Northern California and Oregon, there historically would have been multiple keystone predators within the kelp forest ecosystem who are punching on purple urchins and keeping their population in check,” says Reuven Bank, board chair of SSL. “But the southern sea otter was extirpated across its historic range, so we were left with sunflower stars being the last major keystone predator of purple urchins across over 100 miles of coastline.” “And sunflower stars didn’t just eat urchins, they scared them,” Bank adds. “Urchins can smell a sunflower star approaching, and in healthy kelp forests they hide more and graze less. Even without consuming them, sunflower stars helped keep urchin behavior, and therefore kelp forests, in balance.” Then, in June 2013, tidepool monitors along Washington’s Olympic Peninsula documented an unprecedented sight. The once-sturdy sea stars had turned soft, pale and contorted, their arms curling and detaching from their bodies. By late summer, the same mysterious affliction had surfaced in British Columbia, and it began sweeping both north and south with startling speed. The emerging epidemic, which caused the invertebrates to literally disintegrate, would soon be known as sea star wasting disease. An infamous marine heatwave—nicknamed “The Blob”—had settled over the Pacific by 2014, thrusting the coast into a fever. Ocean temperatures spiked, likely speeding up the disease progression in already stressed sea stars and leading to higher mortality. In the warm, stagnant water, infected sunflower stars dissolved at an eerily rapid pace, leaving behind ghost-white films of bacterial mass where the vibrant predators had been just days before. “You’d have apparently healthy stars basically melt away into puddles of goo within 48 hours,” says Andrew Kim, lab manager at SSL. “It happened so quickly, and I don’t think folks were prepared for the ensuing ecosystem shift. You don’t often expect diseases to come through and totally reshape ecosystem dynamics within such a short period. But that’s what we saw.” Without sunflower sea stars to keep those spiny purple urchins in check, the balance began to falter, setting the stage for an unprecedented chain reaction. Urchin populations skyrocketed, grazing on kelp without limits, and once-thriving underwater forests collapsed into barren rock. A dense group of purple sea urchins, which exploded in population after the sunflower sea stars disappeared, photographed near Mendocino Headlands State Park, north of San Francisco. Brent Durand via Getty Images In California, with 99 percent loss, sunflower sea stars are now considered functionally extinct. “Even though there may be a few remnant individuals left, they can no longer fulfill their historic role in the ecosystem,” Bank says. As sunflower stars unraveled in the wild, another species—its thick-armed cousin, the giant pink star—offered an unexpected foothold for hope. The pink stars share a nearly identical geographic range and life history with sunflower stars, and crucially, their larvae can be raised in aquaria. If scientists could learn to freeze and revive the pink star in its early life stages, they wondered, could that knowledge become a lifeline for the sunflower star? That’s where the small team in Moss Landing stepped in. Freezing sea stars for the future What these scientists did was something no one had ever pulled off with a sea star. Working with giant pink stars, researchers spawned adults at the Aquarium of the Pacific in Long Beach, California, fertilized their gametes to produce thousands of larvae, and shipped those microscopic bodies to the Frozen Zoo—a cryopreserved archive of creatures operated by the San Diego Zoo Wildlife Alliance. There, reproductive scientists plunged the larvae into liquid nitrogen, cooling them to extremely low temperatures and pausing their cells’ biological activity. The larvae, essentially frozen in time, were shielded from ice crystal damage with special cryoprotectant mixtures. Sunflower Star Laboratory researchers remove a vial of pink star larvae from an insulated cooler at around minus 180 degrees Celsius in preparation for thawing. Avery Schuyler Nunn After months in this suspended state, the larvae were sent to the Sunflower Star Laboratory where Carly Young, a San Diego Zoo Wildlife Alliance scientist who advances cryopreservation and reproductive-rescue tools, led the team in thawing the vials. She had fine-tuned the ideal way to keep the larvae alive as they returned to real-world temperatures, carefully testing more than 100 “recipes” with various warming rates, cryoprotectant dilutions and rehydration steps. The pink star larvae not only survived thawing, but have thus far lived all the way through metamorphosis into juveniles. Scientists watched the little stars settle spontaneously along the bottom of their beakers just 19 days after revival. The success prompted the team to apply the same cryopreservation protocols to sunflower star larvae from the Alaska SeaLife Center. The larvae will be frozen in perpetuity, creating the first-ever cryopreserved archive of the species—like a seed bank, but for the baby sea stars. “A famous quote from the ’70s, when the Frozen Zoo in San Diego was established, was, ‘You must collect things for reasons you don’t yet understand,’” says Ashley Kidd, conservation project manager at SSL. “We don’t know when the other shoe is going to drop and what populations are going to look like as the planet changes. So, rather than chasing ghosts around the ocean floor, we really focused on what we can do with animals that are currently under human care somewhere.” While cryopreservation itself isn’t a ready-made restoration tool, it opens the door to conserving genetic diversity of a species and banking rare lineages for potential reintroduction to the wild. In the 1970s and 1990s, researchers began testing cryopreservation of marine invertebrates with sperm and larvae, establishing the basic protocols that this team could apply to sea stars. The breakthrough doesn’t restore kelp forests by itself, but the SSL scientists note that cryopreservation creates something the conservation community has desperately needed: time. Time to hold onto genetic diversity, time to refine captive rearing and time to prepare for future reintroduction at scales big enough to matter. The ultimate test, the researchers say, will be translating the thawing process to sunflower sea stars. Carly Young, at the Sunflower Star Laboratory, looks for movement in the young sea stars. Avery Schuyler Nunn Just this summer, scientists uncovered a piece of the puzzle that had eluded them for more than a decade: the pathogen behind sea star wasting disease. In a four-year international effort, researchers traced the outbreak to a strain of the marine bacterium Vibrio pectenicida. When cultured and injected into healthy sea stars, it reproduced the telltale symptoms—softening arms, rapid disintegration and death within days. The finding, published in Nature Ecology and Evolution in August, gives recovery teams a way to test for the pathogen in labs and hatcheries, tighten quarantine measures and understand disease risks before returning captive-bred sea stars to the Pacific. “It’s massively important to know what to look for, and the fact that we are now able to test for this disease is going to be critical in advancing our ability to move forward with reintroductions and continuing the research,” notes Kim. “We’ve already been able to take fluid samples from all of our stars and get them analyzed for the presence of Vibrio pectenicida, so we’ve mobilized very quickly on the heels of development.” Paired with this new diagnostic clarity, advances in cryopreservation offer a second front in the effort to save the species. Frozen larvae can be stored for decades and offer flexibility for selective breeding of disease-tolerant traits, notes the team. Cryopreservation adds another tool to the scientists’ toolbox as they fight to prevent the species—and, in turn, its ecosystem—from wasting away. “Bringing back sunflower stars,” Bank says, “is the single-most important step we can take toward restoring kelp forest balance.” Get the latest Science stories in your inbox.

Archaeologists Are Unraveling the Mysteries Behind Deep Pits Found Near Stonehenge

Based on a comprehensive study, researchers are now convinced the shafts were human-made, likely dug during the Late Neolithic period roughly 4,000 years ago

Archaeologists Are Unraveling the Mysteries Behind Deep Pits Found Near Stonehenge Based on a comprehensive study, researchers are now convinced the shafts were human-made, likely dug during the Late Neolithic period roughly 4,000 years ago Sarah Kuta - Daily Correspondent December 10, 2025 9:59 a.m. The pits are evenly spaced around a large circle. University of Bradford In 2020, archaeologists in the United Kingdom made a surprising discovery. At Durrington Walls, a large Neolithic henge not far from Stonehenge, they found more than a dozen large, deep pits buried under layers of loose clay. The pits are mysterious. Each one measures roughly 30 feet wide by 15 feet deep, and together they form a mile-wide circle around Durrington Walls and neighboring Woodhenge. They also appear to be linked with the much older Larkhill causewayed enclosure, built more than 1,000 years before Durrington Walls. For the last few years, archaeologists have been puzzling over their origins: Were they dug intentionally by human hands? Were they naturally occurring structures, like sinkholes? Or is there some other possible explanation for the existence of these colossal shafts? Quick fact: The purpose of Durrington Walls While Stonehenge is thought to have been a sacred place for ceremonies, Durrington Walls was a place where people actually lived. In a new paper published in the journal Internet Archaeology, archaeologists report that they have a much better understanding of the pits’ purpose, chronology and environmental setting. And, now, they are confident the shafts were made by humans. “They can’t be occurring naturally,” says lead author Vincent Gaffney, an archaeologist at the University of Bradford, to the Guardian’s Steven Morris. “It just can’t happen. We think we’ve nailed it.” Chris Gaffney, an archaeologist at the at the University of Bradford, surveys the ground near Durrington Walls. University of Bradford For the study, researchers returned to the site in southern England and used several different methods to further analyze the unusual structures. They used a technique known as electrical resistance tomography to calculate the pits’ depths, and radar and magnetometry to suss out their shapes. They also took core samples of the sediment, then ran the soil through a variety of tests. For instance, they used optically stimulated luminescence to determine the last time each layer of soil had been exposed to the sun. They also looked for traces of animal or plant DNA. Astonishing' Stonehenge discovery offers new insights into Neolithic ancestors. Together, the results of these analyses indicate humans must have been involved, which suggests the pits could be “one of the largest prehistoric structures in Britain, if not the largest,” Gaffney tells the BBC’s Sophie Parker. Researchers suspect the circle pits were created by people living at the site over a short period of time during the Late Neolithic period roughly 4,000 years ago. They were not “simply dug and abandoned” but, rather, appear to have been part of a “structured, monumental landscape that speaks to the complexity and sophistication of Neolithic society,” Gaffney says in a statement. For example, the pits are fairly evenly spaced around the circle, which suggests their Neolithic creators were measuring the distances between them somehow. “The skill and effort that must have been required to not only dig the pits, but also to place them so precisely within the landscape is a marvel,” says study co-author Richard Bates, a geophysicist at the University of St Andrews, in a statement. “When you consider that the pits are spread over such a large distance, the fact they are located in a near perfect circular pattern is quite remarkable.” Researchers used multiple methods to investigate the pits at Durrington Walls. University of Bradford But who dug the pits? And, perhaps more importantly, why? Archaeologists are still trying to definitively answer those questions, but they suspect the shafts were created to serve as some sort of sacred boundary around Durrington Walls. Their creators may also have been trying to connect with the underworld, per the Guardian. “They’re inscribing something about their cosmology, their belief systems, into the earth itself in a very dramatic way,” Gaddney tells the BBC.

Is red meat bad for you? Limited research robs us of a clear answer.

We’d all appreciate more definitive guidance. Eating a varied diet is a wise move while we wait.

Over and over, we ask the question: Is Food X good or bad for you? And, over and over, belief in the answer — whether it’s yes or no — is held with conviction totally out of proportion with the strength of the evidence.Today’s illustration: red meat. It has become one of the most-disputed issues in food. It’s so polarizing that some people decide to eat no meat at all, while others decide to eat only meat. It’s poison, or it’s the only true fuel.The latest salvo in the Meat Wars was kicked off by a new report that outlines the optimal diet for both people and planet. The EAT-Lancet Report comes down hard on red meat; its recommended daily intake is a mere 14 grams — that’s half an ounce.Read on, and the news gets worse: “Because intake of red meat is not essential and appears to be linearly related to higher total mortality and risks of other health outcomes in populations that have consumed it for many years, the optimal intake may be zero.”Note that word: “related.” It’s the source of the problem with the report and its recommendation.The EAT-Lancet report, by researchers from 17 countries, bases its recommendation solely on observational data. When you do that, meat comes out looking pretty bad. In study after study, people who report eating a lot of meat have worse health outcomes than people who eat little. Meat-eating correlates with increased risk of heart disease, some cancers and all-cause mortality.But, as always with observational research that attempts to connect the dots between diet and health, the key question is whether the meat itself, or something else associated with a meat-heavy lifestyle, is actually causing the bad outcomes.That’s a hard question to answer, but there are clues that people who eat a lot of meat are very different from people who eat a little.Let’s look at a study, published in JAMA Internal Medicine, cited by the EAT-Lancet report; it has a convenient demographic summary. According to it, people in the top one-fifth of meat eaters are different from people in the bottom fifth in a lot of important ways: They weigh more, they’re more likely to smoke, they’re not as well-educated, they get less exercise, and they report lower intakes of fruit, vegetables and fiber. On the plus side, they report drinking less alcohol. But other than that, we’re looking at a litany of markers for a lifestyle that’s not particularly health-conscious.So, to suss out whether it’s the meat that’s raising disease risk, you have to somehow correct for any of the differences on that list — and most of that information also comes from observational research, so even the confounders are confounded.Then there are the things you can’t correct for. Sleep quality, depression and screen time, for example, all correlate with some of the same diseases meat correlates with, but most studies have no information on those.All this confounding explains one of my all-time favorite findings from observational research. It comes from the same study the demographics came from (analyzed in a 2015 paper). Sure enough, the people who ate the most meat were more likely to die of cancer and heart disease, but they were also more likely to die in accidents. And the biggest difference came from the catchall category “all others,” which invariably includes causes of death that have nothing to do with meat.Basically, there’s a very simple problem with relying on observational research: People who eat a lot of meat are very different from people who eat less of it. The meat definitely isn’t causing the accidental deaths (unless, perhaps, they’re tragic backyard grill mishaps), and it isn’t causing at least some of the “all others” deaths, so we know that heavy and light meat-eaters are different in all kinds of ways.That’s where controlled trials come in.In a perfect world, we could figure this out by keeping a large group of people captive for a lifetime, feeding half of them meat, and seeing what happens. Okay, maybe that’s not a perfect world, but it would be the best solution to this particular problem.Instead, we have trials that are short-term (because of logistics and cost), and necessarily rely on markers for disease, rather than the disease itself. For that to be useful, you need a marker that’s a reliable indicator. For a lot of diseases — including cancer — those are hard to come by. For heart disease, we have a good one: low-density lipoprotein (LDL) cholesterol. So, most of the controlled trials of meat-eating focus on heart disease.If you spend some time reading those trials (and I did, so you don’t have to), you find that most of them show some increase in LDL cholesterol, although it’s generally small.A 2025 analysis of 44 controlled trials on meat found that the only ones showing positive cardiovascular outcomes had links to the meat industry, and even then, only about one in five came out positive. Of the independent studies, about three-quarters showed negative outcomes, and the remaining one-quarter was neutral.This isn’t surprising. Red meat contains saturated fat, and we have countless trials that demonstrate sat fat’s ability to raise LDL. But if the meat you eat is relatively lean, that effect is going to be small.The lesson here is that we don’t have a lot of good evidence on meat and health. The observational evidence is hopelessly confounded, and the evidence from clinical trials is woefully limited. There’s so much we simply don’t know. There may be other ways meat raises risk (leading to over-absorption of heme iron and stimulating the production of TMAO, or trimethylamine N-oxide), but there’s little definitive evidence for them. And, of course, there’s the question of what you eat instead. If you’re eating red meat instead of, say, instant ramen, that may be an improvement. If, instead, you’re cutting back on your lentils, not so much.As always, the single-most important thing to remember about nutrition is that what we know is absolutely dwarfed by what we don’t know. Which means that, if you’re making decisions based on what we do know, you could very well be wrong.So what’s an eater to do? Meat is a nutritious food. In fact, animal foods are the only natural sources of a vitamin we need — B12 — which is an indication that we evolved with meat and dairy as part of our diet. It’s very hard to know whether eating some lean meat leads to better outcomes than eating no meat, but I think some meat is a good hedge against all that uncertainty. (The ethical and environmental concerns are also important, but for today let’s focus on health.)But plant foods are also nutritious. And eating a wide variety of them is also a good hedge against uncertainty. Which means the carnivore diet — all meat, all the time! — is a pretty bad bet.Unfortunately, “uncertainty” is not a word that features prominently in the Meat Wars. Instead, we have an unappetizing combination of nastiness and sanctimony, with each camp convinced that the truth and the light are on their side.Not that this is a metaphor for our times or anything.

New Wildlife Books for Children and Teens (That Adults May Find Interesting Too)

These books for young readers will delight and encourage interest in mammals, insects, octopuses, and other creatures in our shared environment. The post New Wildlife Books for Children and Teens (That Adults May Find Interesting Too) appeared first on The Revelator.

Creating excitement about our amazing planet in young people has never been more important. A pack of new books make environmental science fun and fascinating, teaching children, teens, and even some adults just how diverse and rich our planet’s wildlife and their habitats are to behold. Reading them can encourage us all to become better guardians of the Earth. We’ve adapted the books’ official descriptions below and provided links to the publishers’ sites, but you should also be able to find these books in a variety of formats through your local bookstore or library. Insectopolis By Peter Kuper Award-winning cartoonist Peter Kuper transports readers through the 400-million-year history of insects and the remarkable entomologists who have studied them. This visually immersive work of graphic non-fiction dives into a world where ants, cicadas, bees, and butterflies visit a library exhibition that displays their stories and humanity’s connection to them throughout the ages. Layering history and science, color and design, it tells the remarkable tales of dung beetles navigating by the stars, hawk-size prehistoric dragonflies hunting prey, and mosquitoes changing the course of human history. Read our interview with Kuper. They Work: Honey Bees, Nature’s Pollinators By June Smalls and illustrator Yukari Mishima The newest addition to June Smalls’s nature series, this is a gorgeous nonfiction picture book about life for a hive of honeybees, complete with factoids. Readers learn about the beehive queen, who fights to be queen from the moment she breaks out of her cell. Her job is important, but a hive is only successful if many, many bees are working together. Experience the life cycle of the honeybee up close and personal with this striking picture book. Told in a poetic style along with fun facts on each page for older readers wanting a deeper dive, this book is a beautiful exploration of life inside a beehive — as well as the dangers and predators bees face in the world, including humans. Bison: Community Builders and Grassland Caretakers By Frances Backhouse Bison are North America’s largest land animals. Some 170,000 wood bison once roamed northern regions, while at least 30 million plains bison trekked across the rest of the continent. Almost driven to extinction in the 1800s by decades of slaughter and hunting, this ecological and cultural species supports biodiversity and strengthens the ecosystems around it. This book celebrates the traditions and teachings of Indigenous peoples and looks at how bison lovers of all backgrounds came together to save these iconic animals. Learn about the places where bison are regaining a hoof-hold and meet some of the young people welcoming them back home. Many Things Under a Rock: The Mysteries of Octopuses by David Scheel and Laurel ‘Yoyo’ Scheel This compelling middle-grade adaptation dives deep into the mysteries of one of our planet’s most enigmatic animals. Among all the ocean’s creatures, few are more captivating — or more elusive — than the octopus. Marine biologist David Scheel investigates these strange beings to answer long-held questions: How can we learn more about animals whose perfect camouflage and secretive habitats make them invisible to detection? How does an almost-boneless package of muscle and protein defeat sharks, eels, and other predators while also preying on the most heavily armored animals in the sea? How do octopuses’ bodies work? This fascinating book shows young readers how to embrace the wisdom of the unknown — even if it has more arms than expected. Animal Partnerships: Radical Relationships, Unlikely Alliances, and Other Animal Teams By Ben Hoare and Asia Orlando Discover partnerships from across the animal kingdom with unexpected animal teams around the world who thrive in the wild as they defend, feed, and plot with each other to survive. Friendly, informative explanations are paired with striking photographs and colorful illustrations to make every page captivate the imagination. This unique animal book for children offers impressive facts about previously unknown animal behaviors that are guaranteed to wow adults and children alike. Conker and the Monkey Trap By Hannah Peckham Deep in the jungle, a chameleon named Conker finds two animals in need of his help. Though he first wants to run and hide, he remembers what his mom taught him about being kind and helpful to others. Once Conker saves Sanjeet the lost lorikeet from a puddle, the two of them come across a monkey caught in a trap. Conker and his new friend work together to save the day. This sweet rhyming story will teach young readers the value of friendship and helping those in need. There are plenty of points for discussion and those are aided by the probing questions at the back of the book and the various activities. Mollusks By Kaitlyn Salvatore From the Discover More: Marine Wildlife Series. Not all marine wildlife lives completely underwater. While some mollusks do, other species live both above and below the water’s surface. As readers learn about the different classes of mollusks, they uncover how a mollusk’s body allows it to do amazing things, learning about the unique ways different mollusk species, from slugs to squid to clams, contribute to their environments. Their lifestyles, diet, and the threats to their survival come to life through vivid photographs and age-appropriate text. Becoming an Ecologist: Career Pathways in Science By John A. Wiens What influences a person’s decision to pursue a career in science? And what factors determine the many possible pathways a budding scientist chooses to follow? John A. Wiens traces his journeys through several subfields of ecology — and gives readers an inside look at how science works. He shares stories from his development as an ornithologist, community ecologist, landscape ecologist, and conservation scientist, recounting the serendipities, discoveries, and joys of this branching career. Wiens explores how an individual’s background and interests, life’s contingencies, the influences of key people, and the culture of a discipline can all shape a scientist’s trajectory. This book explores why ecologists ask the questions they do, how they go about answering them, and what they do when the answers are not what they expected. Bringing together personal narrative with practical guidance for aspiring ecologists, this book provides a window onto a dynamic scientific field — and inspiration for all readers interested in building a career by following their passion for the natural world, presented in an enticing way for young professionals and students. Enjoy these engaging reads and get young friends and family members involved with activities that support our environment and wildlife. We hope you and your children and grandchildren will be motivated to protect and reclaim our environment through these remarkable books. And there’s more to come: We’ll cover more books for young readers in the months ahead.
