The indoorsy person’s guide to the great outdoors

Monday, April 22, 2024

Mary Kirkpatrick for Vox Nature is for everyone. Here’s how to enjoy it, no matter where you live. As a dog walker in Southern California, Rubén Arteaga spends a lot of time outside — at nearby parks, the beach, and on mountain trails. Yet with all his attention on the dogs and his mileage tracker, he never really looked at his surroundings. “My whole life,” he says, “I’ve spent my time looking down.” But something shifted in him one day this winter. In the hills above Laguna Beach, Arteaga lifted his head and looked — really looked — at the clouds above, at the trees. He noticed the wildflowers. “I just saw the world was so much brighter, and that there were so many more colors,” he says. “It just made my gray, dim world feel a little brighter.” Now that he pays more attention to his environment, being outdoors brings him a sense of serenity, he says, grounding him in the moment and pushing away thoughts of his to-do list. Arteaga’s experience, though simple, is powerful — and measurable. Spending time outside in green spaces is linked to a number of positive mental and physical health outcomes. People who live in urban areas with greater exposure to green spaces, such as parks or gardens, have better mental health, according to a recent study. Indeed, living near parks, lakes, and beaches is associated with reduced risk of mental health disorders like anxiety and depression, research shows. Further research suggests that people who live near parks age more slowly than those who don’t. Nature is, in a literal sense, healing. Whether or not we recognize these benefits, many people face hurdles to getting outside. Racism, colonialism, and segregation — past and present — have long excluded or displaced Indigenous, nonwhite, and queer people from safely accessing green spaces. People with marginalized backgrounds often feel unsafe in parks. (Look no further than the 2020 incident where a white woman called the police on Christian Cooper, a Black man who was birding in Central Park, because he asked that she leash her dog.) What’s more, a growing majority of the country lives in urban areas and may lack the time or resources to travel to what are traditionally thought of as “natural” environments — parks, forests, rivers, lakes, and oceans. People with physical disabilities may also have difficulty navigating these spaces. Then there are those of us who just don’t consider ourselves outdoorsy: Camping, dirt, and mosquitos don’t sound like a good time. Yet experiencing time in nature and reaping all of its benefits is actually really easy. And it doesn’t matter where you live. From moss on neighborhood trees to the birds outside your window, the natural world is all around us and full of surprises — you just have to start paying attention. “Nature, in my opinion, is deeply embedded around us,” says Yvette Stewart, the community outreach coordinator at Audubon Texas, a nonprofit environmental conservation group. “If people want to start tuning into it, the best thing to do is just pause outside.” Here’s how to find a version of nature that works for you — and some suggestions on how to spend your time there. How to find your place in nature First things first: What does it actually mean to be “in nature”? Nature is not just some faraway landscape full of trees. Any time we’re outside of a building, we are in nature, according to Katrina Clark, a board member of the Philadelphia-based In Color Birding Club: “That is true regardless of whether you live in the country, the suburbs, or the city.” If you hike through the woods or simply stop to admire flowers near the curb, you’re engaging with nature. Humans are an inherent part of nature, Clark says, though for the purpose of this story, we use “nature” to refer to plants, wildlife, and ecosystems. To have a positive experience with the wild world, it can be helpful to first decide what you’re looking for and what kind of restrictions you might have: Do you want to get exercise? To engage your kids? Do you have limited time or no access to a car? These questions will help guide you toward an accessible setting you’ll enjoy. For example, if you love plants, pay attention to how the trees bloom throughout the year, Stewart says. For a kid-friendly weekend activity, try starting a garden with your family (or just planting basil, mint, and other herbs in pots on your windowsill). Maybe you’re looking for a social activity instead: Search for local birding clubs or guided hikes. Consider the time of year, too. You may want to pay close attention to the sky in the spring and fall when birds migrate. (Bird migration forecast maps can help you figure out the best time and places to see them.) Similarly, think of experiences you want to avoid. If you really hate mosquitos, try spending time outside when it’s still chilly, such as in late fall or early spring. People from communities that have been historically excluded from green spaces will have different considerations. “Coming back to those areas for people of color can be scary and be risky,” says Marc Chavez, the founder and director of Native Like Water, a nonprofit focusing on water. “You have to use precaution. You have to also help get over psychological trauma based on those areas.” To help overcome these personal emotional wounds, Chavez says it can be helpful to remember that any land, mountains, or rivers existed for thousands of years before they became a neighborhood, a national park, or a colonized territory. How to access nature Start small. One of the most universal pieces of advice we received from experts is to spend more time observing plant and animal life in your immediate surroundings. That could be a tree in your backyard, birds on top of buildings, or a neighborhood garden. “It could be something as simple as seeing the grass that is growing between the cracks [in the sidewalk] after a rain,” says He Sung Im, the public programs manager at Audubon Center at Debs Park. If you’re feeling more adventurous, look for nearby city and state parks — they’re often a great place to start. If you live in a city and don’t have a car, check out where public transit can bring you. Even if you live in a place as urban as Manhattan, you can still hike within the city. “Take the A-train and go to Inwood Hill Park,” says Georgina Cullman, an ecologist for the NYC Department of Parks & Recreation. If you want a longer hike, just take the Metro-North train to the Hudson Valley, she says. (Pro tip: Wear long pants, use bug spray, and check your body — and your pet’s — for ticks when you get home. Shower, too.) For help finding appropriate hiking trails, check out websites like TrailLink and AllTrails, which list hikes by difficulty level. AllTrails also maintains a list of over 8,000 wheelchair-friendly trails nationwide. Similarly, the National Park Service has a list of accessibility features online for the country’s parks and monuments. Living near a park is a privilege. Across the country, 100 million people do not have a park within a 10-minute walk from their homes. Parks primarily serving people of color are, on average, half the size of those in predominantly white neighborhoods. For those who don’t have access to reliable transportation and who don’t live near a park, try reaching out to nearby community groups (of birders, hikers, swimmers, etc.) — they may be able to help. For instance, Chavez founded Native Like Water in order to provide Native Americans who no longer had access to the ocean a comfortable, safe space to reconnect to the coastal environment. Initiatives include a 10-day youth program where participants explore the San Diego coastline while learning about the Indigenous peoples of the area, the ecology, and how to surf. Historic barriers to accessibility remain for members of marginalized communities; take the Audubon Society, named after John James Audubon, a naturalist who enslaved others. Despite this history, younger and more diverse populations are reclaiming these spaces and activities — and making them more welcoming to all. What to do outdoors So you’ve figured out where to go. What do you do once you’re there? The easiest thing is, essentially, nothing. Just wander. “There should be no rush,” Chavez says. What’s most important is slowing down and observing what’s in front of you, no matter where you are, even on a five-minute walk outside your office. Pay attention to the creatures around you, the way the sun or the wind feels on your skin, the smell of moist soil. If you feel like engaging a bit more with the space, check to see if there are any community groups or other organizations that oversee it. Places like gardens, arboretums, and nature centers often host tours and other events that will introduce you to the space and get you mingling with the community. Similarly, Facebook groups or “friends of” websites list community-led events and initiatives. Several experts also recommended bringing a friend, especially someone who likes the outdoors more than you. Then, you can determine which aspects of the environment most interest you and what you should keep an eye on next time. You don’t even need to move at all. Clark suggests hanging out at outdoor beer gardens with plants and greenery if you want to socialize in the open air (yes, even that is time in nature!). Or instead of walking up steep trails to look for birds, try a “bird sit,” Im said. Find a nice spot with trees, stay quiet, and observe the birds around you. “We started doing bird sits because we realized a lot of city people are not really comfortable doing hikes,” Im says. To make it even easier, download an app called Merlin, which is essentially Shazam for bird calls; it will listen to and identify the birds around you. “The beautiful thing about birds is they’re literally found everywhere,” Stewart said. If birds aren’t your thing, you could also try insect watching. Hear us out: When flowers are in bloom, dozens of insects may visit them in a single day to slurp up nectar or gather pollen, including butterflies, beetles, and bees. Sit next to some flowers and just watch. It’s relaxing — we swear! If there’s a lake or stream at your destination, consider getting in the water — or even just being next to water. Research shows that looking at bodies of water can lower your heart rate and blood pressure and help you feel relaxed. Consider picnicking by a local reservoir or, better yet, renting a kayak or canoe. Some cities lend them out for free. “One of my favorite things that I get to do for my job,” Cullman says, “is getting to go out on a kayak and see different parts of the city.” If you do, indeed, want to go camping, there are plenty of options short of trekking into the woods with your own gear. Some state parks run programs for a fee that will take you out camping for a night, even if you don’t have much experience or own your own gear. We’re also big fans of low-maintenance car camping. Instead of pitching a tent, you can sleep in your car near a trailhead that allows overnight parking. Then high tail it to the nearest diner for breakfast in the morning. You can even bring an air mattress out to your backyard. No planning required. One very important note: No matter where you go, always be respectful to wildlife and other people. Pick up trash and dog poop, which can pollute streams and spread disease, even if it’s not yours. Do not police people’s behaviors. If you’re in a state park and there are loud children nearby, perhaps walk to another section of the park. Green spaces should be for everyone. On the flip side, if you see people trying to observe birds or other animals, use a quieter voice. What gear and tools you’ll need The good news is that you don’t really need anything. That said, you’ll be more comfortable outside with a good hat, large water bottle (Stewart recommends CamelBak), and sturdy shoes. Even if you’re looking for birds, binoculars aren’t a necessity. You can use the zoom feature on your phone camera, Im suggests. Some stores also rent binoculars or even provide them for free. The best tools to enjoy time outside are free apps and websites. On platforms like iNaturalist, eBird, and PlantNet, you can browse nearby sightings of plants and animals and upload your own photos. A tool called BirdCast shows real-time maps and forecasts of bird migration, so you know where and when to look. A number of different apps, like Seek, will help you identify plants and even animals by just taking photos of them. And again, Merlin is a great platform for IDing birds by their calls alone. Ultimately, a lot of what will make experiencing nature easier and more enjoyable is a shift in perspective — a shift in the way we view what nature is. “If you acknowledge [nature] as being any space that’s outside, where you can feel the wind and you can see the sun and you can get wet from a rainstorm, then it starts to bring nature back into your tangible world,” Stewart said. “Nature is all around us even in the most urban places in the world.”

Contributor: 'Save the whales' worked for decades, but now gray whales are starving

The once-booming population that passed California twice a year has cratered because of retreating sea ice. A new kind of intervention is needed.

Recently, while sailing with friends on San Francisco Bay, I enjoyed the sight of harbor porpoises, cormorants, pelicans, seals and sea lions — and then the spouting plume and glistening back of a gray whale that gave me pause. Too many have been seen inside the bay recently.California’s gray whales have been considered an environmental success story since the passage of the 1972 Marine Mammal Protection Act and 1986’s global ban on commercial whaling. They’re also a major tourist attraction during their annual 12,000-mile round-trip migration between the Arctic and their breeding lagoons in Baja California. In late winter and early spring — when they head back north and are closest to the shoreline, with the moms protecting the calves — they can be viewed not only from whale-watching boats but also from promontories along the California coast including Point Loma in San Diego, Point Lobos in Monterey and Bodega Head and Shelter Cove in Northern California.In 1972, there were some 10,000 gray whales in the population on the eastern side of the Pacific. Generations of whaling all but eliminated the western population — leaving only about 150 alive today off of East Asia and Russia. Over the four decades following passage of the Marine Mammal Protection Act, the eastern whale numbers grew steadily to 27,000 by 2016, a hopeful story of protection leading to restoration. Then, unexpectedly over the last nine years, the eastern gray whale population has crashed, plummeting by more than half to 12,950, according to a recent report by the National Oceanic and Atmospheric Administration, the lowest numbers since the 1970s.Today’s changing ocean and Arctic ice conditions linked to fossil-fuel-fired climate change are putting this species again at risk of extinction.While there has been some historical variation in their population, gray whales — magnificent animals that can grow up to 50 feet long and weigh as much as 80,000 pounds — are now regularly starving to death as their main food sources disappear. This includes tiny shrimp-like amphipods in the whales’ summer feeding grounds in the Arctic. It’s there that the baleen filter feeders spend the summer gorging on tiny crustaceans from the muddy bottom of the Bering, Chuckchi and Beaufort seas, creating shallow pits or potholes in the process. But, with retreating sea ice, there is less under-ice algae to feed the amphipods that in turn feed the whales. Malnourished and starving whales are also producing fewer offspring.As a result of more whales washing up dead, NOAA declared an “unusual mortality event” in California in 2019. Between 2019 and 2025, at least 1,235 gray whales were stranded dead along the West Coast. That’s eight times greater than any previous 10-year average.While there seemed to be some recovery in 2024, 2025 brought back the high casualty rates. The hungry whales now come into crowded estuaries like San Francisco Bay to feed, making them vulnerable to ship traffic. Nine in the bay were killed by ship strikes last year while another 12 appear to have died of starvation.Michael Stocker, executive director of the acoustics group Ocean Conservation Research, has been leading whale-viewing trips to the gray whales’ breeding ground at San Ignacio Lagoon in Baja California since 2006. “When we started going, there would be 400 adult whales in the lagoon, including 100 moms and their babies,” he told me. “This year we saw about 100 adult whales, only five of which were in momma-baby pairs.” Where once the predators would not have dared to hunt, he said that more recently, “orcas came into the lagoon and ate a couple of the babies because there were not enough adult whales to fend them off.”Southern California’s Gray Whale Census & Behavior Project reported record-low calf counts last year.The loss of Arctic sea ice and refusal of the world’s nations recently gathered at the COP30 Climate Summit in Brazil to meet previous commitments to reduce greenhouse gas emissions suggest that the prospects for gray whales and other wildlife in our warming seas, including key food species for humans such as salmon, cod and herring, look grim.California shut down the nation’s last whaling station in 1971. And yet now whales that were once hunted for their oil are falling victim to the effects of the petroleum or “rock oil” that replaced their melted blubber as a source of light and lubrication. That’s because the burning of oil, coal and gas are now overheating our blue planet. While humans have gone from hunting to admiring whales as sentient beings in recent decades, our own intelligence comes into question when we fail to meet commitments to a clean carbon-free energy future. That could be the gray whales’ last best hope, if there is any.David Helvarg is the executive director of Blue Frontier, an ocean policy group, and co-host of “Rising Tide: The Ocean Podcast.” He is the author of the forthcoming “Forest of the Sea: The Remarkable Life and Imperiled Future of Kelp.”

Pills that communicate from the stomach could improve medication adherence

MIT engineers designed capsules with biodegradable radio frequency antennas that can reveal when the pill has been swallowed.

In an advance that could help ensure people are taking their medication on schedule, MIT engineers have designed a pill that can report when it has been swallowed.The new reporting system, which can be incorporated into existing pill capsules, contains a biodegradable radio frequency antenna. After it sends out the signal that the pill has been consumed, most components break down in the stomach while a tiny RF chip passes out of the body through the digestive tract.This type of system could be useful for monitoring transplant patients who need to take immunosuppressive drugs, or people with infections such as HIV or TB, who need treatment for an extended period of time, the researchers say.“The goal is to make sure that this helps people receive the therapy they need to help maximize their health,” says Giovanni Traverso, an associate professor of mechanical engineering at MIT, a gastroenterologist at Brigham and Women’s Hospital, and an associate member of the Broad Institute of MIT and Harvard.Traverso is the senior author of the new study, which appears today in Nature Communications. Mehmet Girayhan Say, an MIT research scientist, and Sean You, a former MIT postdoc, are the lead authors of the paper.A pill that communicatesPatients’ failure to take their medicine as prescribed is a major challenge that contributes to hundreds of thousands of preventable deaths and billions of dollars in health care costs annually.To make it easier for people to take their medication, Traverso’s lab has worked on delivery capsules that can remain in the digestive tract for days or weeks, releasing doses at predetermined times. However, this approach may not be compatible with all drugs.“We’ve developed systems that can stay in the body for a long time, and we know that those systems can improve adherence, but we also recognize that for certain medications, we can’t change the pill,” Traverso says. “The question becomes: What else can we do to help the person and help their health care providers ensure that they’re receiving the medication?”In their new study, the researchers focused on a strategy that would allow doctors to more closely monitor whether patients are taking their medication. Using radio frequency — a type of signal that can be easily detected from outside the body and is safe for humans — they designed a capsule that can communicate after the patient has swallowed it.There have been previous efforts to develop RF-based signaling devices for medication capsules, but those were all made from components that don’t break down easily in the body and would need to travel through the digestive system.To minimize the potential risk of any blockage of the GI tract, the MIT team decided to create an RF-based system that would be bioresorbable, meaning that it can be broken down and absorbed by the body. The antenna that sends out the RF signal is made from zinc, and it is embedded into a cellulose particle.“We chose these materials recognizing their very favorable safety profiles and also environmental compatibility,” Traverso says.The zinc-cellulose antenna is rolled up and placed inside a capsule along with the drug to be delivered. The outer layer of the capsule is made from gelatin coated with a layer of cellulose and either molybdenum or tungsten, which blocks any RF signal from being emitted.Once the capsule is swallowed, the coating breaks down, releasing the drug along with the RF antenna. The antenna can then pick up an RF signal sent from an external receiver and, working with a small RF chip, sends back a signal to confirm that the capsule was swallowed. This communication happens within 10 minutes of the pill being swallowed.The RF chip, which is about 400 by 400 micrometers, is an off-the-shelf chip that is not biodegradable and would need to be excreted through the digestive tract. All of the other components would break down in the stomach within a week.“The components are designed to break down over days using materials with well-established safety profiles, such as zinc and cellulose, which are already widely used in medicine,” Say says. “Our goal is to avoid long-term accumulation while enabling reliable confirmation that a pill was taken, and longer-term safety will continue to be evaluated as the technology moves toward clinical use.”Promoting adherenceTests in an animal model showed that the RF signal was successfully transmitted from inside the stomach and could be read by an external receiver at a distance up to 2 feet away. If developed for use in humans, the researchers envision designing a wearable device that could receive the signal and then transmit it to the patient’s health care team.The researchers now plan to do further preclinical studies and hope to soon test the system in humans. One patient population that could benefit greatly from this type of monitoring is people who have recently had organ transplants and need to take immunosuppressant drugs to make sure their body doesn’t reject the new organ.“We want to prioritize medications that, when non-adherence is present, could have a really detrimental effect for the individual,” Traverso says.Other populations that could benefit include people who have recently had a stent inserted and need to take medication to help prevent blockage of the stent, people with chronic infectious diseases such as tuberculosis, and people with neuropsychiatric disorders whose conditions may impair their ability to take their medication.The research was funded by Novo Nordisk, MIT’s Department of Mechanical Engineering, the Division of Gastroenterology at Brigham and Women’s Hospital, and the U.S. Advanced Research Projects Agency for Health (ARPA-H), which notes that the views and conclusions contained in this article are those of the authors and should not be interpreted as representing the official policies, either expressed or implied, of the United States Government.

A young female manatee washed up alone on a beach in Tortuguero National Park early on January 5, sparking a coordinated effort by local authorities to save the animal. The calf, identified as a Caribbean manatee, appeared separated from its mother, with no immediate signs of her in the area. Park rangers received the first alert around 8 a.m. from visitors who spotted the stranded calf. Staff from the National System of Conservation Areas (SINAC) quickly arrived on site. They secured the animal to prevent further harm and began searching nearby waters and canals for the mother. Despite hours of monitoring, officials found no evidence of her presence. “The calf showed no visible injuries but needed prompt attention due to its age and vulnerability,” said a SINAC official involved in the operation. Without a parent nearby, the young manatee faced risks from dehydration and predators in the open beach environment. As the day progressed, the Ministry of Environment and Energy (MINAE) joined the response. They decided to relocate the calf for specialized care. In a first for such rescues in the region, teams arranged an aerial transport to move the animal safely to a rehabilitation facility. This step aimed to give the manatee the best chance at survival while experts assess its health. Once at the center, the calf received immediate feeding and medical checks. During one session, it dozed off mid-meal, a sign that it felt secure in the hands of caretakers. Biologists now monitor the animal closely, hoping to release it back into the wild if conditions allow. Manatees, known locally as manatíes, inhabit the coastal waters and rivers of Costa Rica’s Caribbean side. They often face threats from boat strikes, habitat loss, and pollution. Tortuguero, with its network of canals and protected areas, serves as a key habitat for the species. Recent laws have strengthened protections, naming the manatee a national marine symbol to raise awareness. This incident highlights the ongoing challenges for wildlife in the area. Local communities and tourists play a key role in reporting sightings, which can lead to timely interventions. Authorities encourage anyone spotting distressed animals to contact SINAC without delay. The rescue team expressed gratitude to those who reported the stranding. Their quick action likely saved the calf’s life. As investigations continue, officials will determine if environmental factors contributed to the separation. For now, the young manatee rests under professional care, a small win for conservation efforts in Limón.

New Records Reveal the Mess RFK Jr. Left When He Dumped a Dead Bear in Central Park

Robert F. Kennedy Jr. says he left a bear cub's corpse in Central Park in 2014 to "be fun." Records newly obtained by WIRED show what he left New York civil servants to clean up.

This story contains graphic imagery.On August 4, 2024, when now-US health secretary Robert F. Kennedy Jr. was still a presidential candidate, he posted a video on X in which he admitted to dumping a dead bear cub near an old bicycle in Central Park 10 years prior, in a mystifying attempt to make the young bear’s premature death look like a cyclist’s hit and run.WIRED's Guide to How the Universe WorksYour weekly roundup of the best stories on health care, the climate crisis, new scientific discoveries, and more. At the time, Kennedy said he was trying to get ahead of a story The New Yorker was about to publish that mentioned the incident. But in coming clean, Kennedy solved a decade-old New York City mystery: How and why had a young black bear—a wild animal native to the state, but not to modern-era Manhattan—been found dead under a bush near West 69th Street in Central Park?WIRED has obtained documents that shed new light on the incident from the New York City Department of Parks and Recreation via a public records request. The documents—which include previously unseen photos of the bear cub—resurface questions about the bizarre choices Kennedy says he made, which left city employees dealing with the aftermath and lamenting the cub’s short life and grim fate.A representative for Kennedy did not respond for comment. The New York Police Department (NYPD) and the Parks Department referred WIRED to the New York Department of Environmental Conservation (NYDEC). NYDEC spokesperson Jeff Wernick tells WIRED that its investigation into the death of the bear cub was closed in late 2014 “due to a lack of sufficient evidence” to determine if state law was violated. They added that New York’s environmental conservation law forbids “illegal possession of a bear without a tag or permit and illegal disposal of a bear,” and that “the statute of limitations for these offenses is one year.”The first of a number of emails between local officials coordinating the handling of the baby bear’s remains was sent at 10:16 a.m. on October 6, 2014. Bonnie McGuire, then-deputy director at Urban Park Rangers (UPR), told two colleagues that UPR sergeant Eric Handy had recently called her about a “dead black bear” found in Central Park.“NYPD told him they will treat it like a crime scene so he can’t get too close,” McGuire wrote. “I’ve asked him to take pictures and send them over and to keep us posted.”“Poor little guy!” McGuire wrote in a separate email later that morning.According to emails obtained by WIRED, Handy updated several colleagues throughout the day, noting that the NYDEC had arrived on scene, and that the agency was planning to coordinate with the NYPD to transfer the body to the Bronx Zoo, where it would be inspected by the NYPD’s animal cruelty unit and the ASPCA. (This didn’t end up happening, as the NYDEC took the bear to a state lab near Albany.)Imagery of the bear has been public before—local news footage from October 2014 appears to show it from a distance. However, the documents WIRED obtained show previously unpublished images that investigators took of the bear on the scene, which Handy sent as attachments in emails to McGuire. The bear is seen laying on its side in an unnatural position. Its head protrudes from under a bush and rests next to a small patch of grass. Bits of flesh are visible through the bear’s black fur, which was covered in a few brown leaves.Courtesy of NYC Parks

U.S. Military Ends Practice of Shooting Live Animals to Train Medics to Treat Battlefield Wounds

The 2026 National Defense Authorization Act bans the use of live animals in live fire training exercises and prohibits "painful" research on domestic cats and dogs

U.S. Military Ends Practice of Shooting Live Animals to Train Medics to Treat Battlefield Wounds The 2026 National Defense Authorization Act bans the use of live animals in live fire training exercises and prohibits “painful” research on domestic cats and dogs Sarah Kuta - Daily Correspondent January 5, 2026 12:00 p.m. The U.S. military will no longer shoot live goats and pigs to help combat medics learn to treat battlefield injuries. Pexels The United States military is no longer shooting live animals as part of its trauma training exercises for combat medics. The 2026 National Defense Authorization Act, which was enacted on December 18, bans the use of live animals—including dogs, cats, nonhuman primates and marine mammals—in any live fire trauma training conducted by the Department of Defense. It directs military leaders to instead use advanced simulators, mannequins, cadavers or actors. According to the Associated Press’ Ben Finley, the bill ends the military’s practice of shooting live goats and pigs to help combat medics learn to treat battlefield injuries. However, the military is allowed to continue other practices involving animals, including stabbing, burning and testing weapons on them. In those scenarios, the animals are supposed to be anesthetized, per the AP. “With today’s advanced simulation technology, we can prepare our medics for the battlefield while reducing harm to animals,” says Florida Representative Vern Buchanan, who advocated for the change, in a statement shared with the AP. He described the military’s practices as “outdated and inhumane” and called the move a “major step forward in reducing unnecessary suffering.” Quick fact: What is the National Defense Authorization Act? The National Defense Authorization Act, or NDAA, is a law passed each year that authorizes the Department of Defense’s appropriated funds, greenlights the Department of Energy’s nuclear weapons programs and sets defense policies and restrictions, among other activities, for the upcoming fiscal year. Organizations have opposed the military’s use of live animals in trauma training, too, including the Physicians Committee for Responsible Medicine and the People for the Ethical Treatment of Animals. PETA, a nonprofit animal advocacy group, described the legislation as a “major victory for animals” that will “save countless animals from heinous cruelty” in a statement. The legislation also prohibits “painful research” on domestic cats and dogs, though exceptions can be made under certain circumstances, such as interests of national security. “Painful” research includes any training, experiments or tests that fall into specific pain categories outlined by the U.S. Department of Agriculture. For example, military cats and dogs can no longer be exposed to extreme environmental conditions or noxious stimuli they cannot escape, nor can they be forced to exercise to the point of distress or exhaustion. The bill comes amid a broader push to end the use of live animals in federal tests, studies and training, reports Linda F. Hersey for Stars and Stripes. After temporarily suspending live tissue training with animals in 2017, the U.S. Coast Guard made the ban permanent in 2018. In 2024, U.S. lawmakers directed the Department of Veterans Affairs to end its experiments on cats, dogs and primates. And in May 2025, the U.S. Navy announced it would no longer conduct research testing on cats and dogs. As the Washington Post’s Ernesto Londoño reported in 2013, the U.S. military has used animals for medical training since at least the Vietnam War. However, the practice largely went unnoticed until 1983, when the U.S. Army planned to anesthetize dogs, hang them from nylon mesh slings and shoot them at an indoor firing range in Maryland. When activists and lawmakers learned of the proposal, they decried the practice and convinced then-Defense Secretary Caspar Weinberger to ban the shooting of dogs. However, in 1984, the AP reported the U.S. military would continue shooting live goats and pigs for wound treatment training, with a military medical study group arguing “there is no substitute for the live animals as a study object for hands-on training.” In the modern era, it’s not clear how often and to what extent the military uses animals, per the AP. And despite the Department of Defense’s past efforts to minimize the use of animals for trauma training, a 2022 report from the Government Accountability Office, the watchdog agency charged with providing fact-based, nonpartisan information to Congress, determined that the agency was “unable to fully demonstrate the extent to which it has made progress.” The Defense Health Agency, the U.S. government entity responsible for the military’s medical training, says in a statement shared with the AP that it “remains committed to replacement of animal models without compromising the quality of medical training,” including the use of “realistic training scenarios to ensure medical providers are well-prepared to care for the combat-wounded.” Animal activists say technology has come a long way in recent decades so, beyond the animal welfare concerns, the military simply no longer needs to use live animals for training. Instead, military medics can simulate treating battlefield injuries using “cut suits,” or realistic suits with skin, blood and organs that are worn by a live person to mimic traumatic injuries. However, not everyone agrees. Michael Bailey, an Army combat medic who served two tours in Iraq, told the Washington Post in 2013 that his training with a sedated goat was invaluable. “You don’t get that [sense of urgency] from a mannequin,” he told the publication. “You don’t get that feeling of this mannequin is going to die. When you’re talking about keeping someone alive when physics and the enemy have done their best to do the opposite, it’s the kind of training that you want to have in your back pocket.” Get the latest stories in your inbox every weekday.
