After looking at 62 mammal species on six continents, a recent study published in Science found that 83 percent of these species are doing more and more of their business in the dark rather than deal with humans and all of our accompanying guns, cars, noise and other forms of harassment.
"Human activity is creating a more nocturnal natural world," said lead author Kaitlyn Gaynor, an ecologist at the University of California at Berkeley. Gaynor said the trend is both powerful and striking.
Deer? Wild pigs? Coyotes? All of them are increasing their nocturnality in an effort to avoid spending time with us. Heck, even tigers—easily some of the planet's scariest predators—are turning into night owls to avoid the Homo sapiens.
And no wonder. Humans make insufferable metaphorical roommates.
For starters, we're loud.
The hum from our cars and airplanes numb South African dwarf mongooses to noises made by approaching predators. The 24/7 cacophony produced by oil and gas operations drives away grasshoppers, crickets and ants and causes bluebirds to have fewer chicks. And you can't even go underwater to get some peace and quiet. Our generators, propellers, engines, and military sonar drone so incessantly, they cause dolphins to lose their breath as they dive and make the hearts of narwhals go haywire. This aquatic ruckus may even overshadow the soft whispers shared between baby humpback whale calves and their mommies.
And we're prone to fits of violence.
In Colorado, the government is spending $4.5 million dollars to kill black bears and mountain lions on a hunch that it might increase deer numbers, because people there like to hunt deer. And in 2017, the U.S. Department of Agriculture killed 23,646 beavers—one every 22 minutes—because beavers modify the environment in ways that are inconvenient for us. (Felling trees and building dams―perhaps the beavers are too similar to us for their own good.)
Tough tamarins, you might say. If the beasts don't like it, they can move out. Well, no, they can't.
Because we don't share (the planet) well.

The habitat market is garbage these days. The forested mountaintops inhabited by woodland caribou have been carved up to extract tar sands. The creeks and streams that are home to the beaverpond marstonia snail have been sucked dry for irrigation and drinking water. The Ridgway's hawk's rainforests have been razed for livestock pastures and coffee plantations. And the polar bear's sea ice? It's being liquidated as we speak.
More and more species are having to figure out how to survive in a space shared with humans—even if that means altering behaviors that have evolved over millennia. According to the new paper, "In places where wild animals co-occur with humans, animals may minimize risk by separating themselves in time rather than in space." That wording kind of makes it sound like bonobos, binturongs, and springboks are cracking the code on interdimensional time travel, but really they're just waiting for us to call it a day, go indoors, and leave them alone.
Just look at the sable antelopes of Zimbabwe. Under normal conditions, these grazers venture down to water holes during the day because lions, hyenas, and other predators prowl such places at night. But a 2012 study found that when you apply a little pressure from trophy hunters during daylight hours, the antelopes suddenly start taking their chances with the lions creeping around in the black of night.
The leopards of Gabon use a similar tactic to avoid bushmeat hunters. In areas without many people, the cats split their waking hours between day and night almost equally (46 percent nocturnality). But in areas where hunting is prevalent, the leopards forsake the sun and spend 93 percent of their waking hours in the dark.
Our mere presence is intimidating.
It's not just the loud and lethal guns scaring them into hiding. Just having humans walk through the forest causes Sumatran sun bears to go dark (19 percent nocturnality in low disturbance, versus 90 percent when scientists come plodding along). The same is true for big, gnarly brown bears in Alaska, who choose the night life to avoid tourists during the day (33 percent nocturnality in low disturbance, versus 76 percent in high disturbance). To be fair, though, tourists are the worst.
Could this be a good thing? Have animals discovered a way to peacefully cohabit with us? After all, some urban dwellers—raccoons, pigeons, rats—are doing fabulously as our neighbors.
Sure, it's certainly possible for some animals to thrive in proximity to us as we slumber. "In Nepal, for example, tigers and people share the exact same trails in the forest at different times of day, reducing direct conflict between humans and these large carnivores," said Gaynor. In this case, both species benefit.
But some wildlife isn't equipped for such an adjustment. "Not all animals are willing or able to just switch to a nocturnal lifestyle around people," she said. For those, we'll need to set aside areas that remain relatively free from our influence, whether that means establishing no-hunting zones, combating climate change, or even just cutting down on human foot traffic.
Further, expecting animals to forgo thousands of years of tried-and-true survival strategies just so they can adapt to our various needs and whims is a bit selfish. It's sort of like saying, "Oh, I let Trudy do the dishes because she cares more about them getting done."
Just, no. Everyone should do the dishes. We need to stop asking every other living thing on earth to bend to us, to pick up our slack. Frankly, I think it's time for a house meeting.
What is Krill Oil?
Krill oil is made from a tiny, shrimp-like crustaceans that live in the ocean and usually serve as whale food. In fact, krill means "whale food" in Norwegian. These tiny organisms actually play an extremely important role in the food chains of marine ecosystems. The krill used to make krill oil are usually found in the waters around Antarctica.
Just like the fish oils found in supplements, krill oil is rich in omega 3 fatty acids that contain EPA and DHA, two compounds that are proven to have a number of health benefits. Krill oil can help support healthy skin, in addition to other vitamin supplements for dry skin.
But what makes krill oil better than fish oil?
It's believed that krill oil is better absorbed in the body than fish oil. Both derive most of their benefits through the EPA and DHA that are contained in their fatty acid stores. However, for the same dose, krill oil will result in more fatty acids in the blood than fish oil. A potential explanation for this is that while fish oil's fatty acids come as triglycerides, krill oil's come as phospholipids which are more easily processed by the body.
Additionally, krill oil contains astaxanthin which is an antioxidant that has anti-inflammatory properties that might have an enhanced positive effect on heart health. Studies have shown that krill oil is more effective than fish oil at lowering blood pressure and lowering bad cholesterol.

The Research on Krill Oil Supplements
Research has long demonstrated the health benefits of omega-3 fatty acids commonly found in foods like fish, nuts, and certain grains like flax seed. Since krill oil naturally contains higher levels of these beneficial nutrients, it has also been found to provide a number of health benefits.
Numerous studies have linked the omega-3 fatty acids found in fish and krill oil to cardiovascular health, finding that those who ingest higher levels of these nutrients are at lower risk for coronary heart disease, potentially lower risk of stroke, and have lower cholesterol levels. Another study found that krill oil supplements offer a safe alternative to fish oil for those seeking cardiovascular benefits in a smaller and more convenient form.
Krill oil supplementation has also been found to help reduce the symptoms of knee and joint pain.
Additionally, researches found that rats given krill oil supplements showed improved cognitive function and benefited from anti-depressant-like effects. However, more research on its effect for human brain development and function is needed.
How to Choose the Right Krill Oil Supplement
When shopping for a krill oil supplement, there are important pieces of information that you should always look for. Here are some tips on how to compare brands and how to read labels.
What to Look For
Lab Testing
For any supplement, always check to see if it has undergone third-party lab testing for quality and safety. This is especially important for any fish or krill oil to make sure that it does not contain any harmful compounds like mercury.
Concentrations
Look for the amount of krill oil contained in each capsule and each serving (as these will sometimes differ). You should choose supplements that offer between 200 mg and 350 mg of omega-3 fatty acids per serving for the best results.
Sourcing
Make it a priority to learn where the brand sources its supply of krill oil. We recommend brands that use sustainably-harvested Antarctic krill oil because the process of harvesting is more tightly regulated by various groups.
Filler-Free
This is good advice for all nutritional supplements, but be sure the krill oil you choose does not contain any unwanted or unnecessary ingredients. All of our recommendations contain just the krill oil and the capsule it comes in.
How to Read Labels
When you are comparing krill oil supplements, here are some key things to look for on any label:
- Supplement Facts - This is where you can find information on the amount of krill oil in each capsule, how many capsules make up one serving, and a breakdown of how many omega-3 fatty acids and other nutrients are contained in the supplement.
- Other Ingredients - Listed at the bottom of the supplement facts table, this list will tell you what the capsule itself is made of and if there are any additional ingredients present.
- Certifications - Check the label for important certifications and seals of approvals that can tell you if a krill oil is IKOS-certified, third-party lab tested, or sustainably harvest.
How to Use Krill Oil Supplements
Krill oil supplements typically come in capsules that you swallow with water, just like any probiotic supplements, digestive enzymes, or vitamin supplements to boost your immune system. For most brands, 2 to 3 capsules make up a single serving, and you can take a serving either once or twice per day. Some brands recommend their supplements be taken with food to aid in their digestion and absorption.
Safety & Side Effects
While krill oil supplements are generally considered safe for most adults, it is extremely important to note that you should not take krill oil if you are allergic to shellfish. The potential side effects for krill oil are considered mild and similar to fish oils, including:
- Upset stomach
- Fishy taste
- Heartburn
- Nausea
- Diarrhea
Still, soil erosion, loads of litter, and risky animal encounters are entirely preventable if you stick to a few simple guidelines.
Plan your trip.
Whether you're a newbie or a 2,000 miler, taking off for a quick hike or embarking on a weeklong backpacking trip, never head outdoors haphazardly. "Always know exactly where you're going and what the conditions and weather are," Watts said. "Having the right gear, food, and clothing means you won't have to make bad decisions in the name of safety." The National Park Service (NPS) has a handy trip-planning guide that includes a list of "Ten Essentials" to help you stay safe on the trail; the list includes a navigation system, sun protection, insulation, illumination, a first-aid kit, a repair kit, nutrition, hydration, emergency shelter, and a fire kit. And speaking of flames, the NPS also provides a useful guide on safely building and extinguishing campfires. You'll definitely want to consult this guide before you get started, since research shows that 84 percent of wildfires are caused by humans.

Follow the posted rules.
Many hikers and campers head out into nature in pursuit of a rush of freedom, but this feeling of liberation doesn't mean that anything goes. "Most public lands have regulations that all visitors must abide by, like having campfires only in designated areas, safely storing food, and not flying drones," said Mark Wenzler, senior vice president of conservation programs at the National Parks Conservation Association. (As drones gain popularity, they bring certain risks to the landscape, as happened in 2014 when one crashed into a famous Yellowstone hot spring; the devices have since been banned in our parks.) To find out the rules for visiting a given park, be sure to check the "plan your visit" section of its website before heading out.

Stick to the trail.
Yes, it's the wilderness. But "the trail is there for a reason," Watts said. "Staying on durable surfaces helps protect vegetation." That's especially true on switchbacks. These paths are designed to prevent erosion, so never cut across. On any trail, you'll do less damage if you keep your group size small and always walk single file straight down the middle.
Handle your trash.
You know to pack up every last thing from your campsite and to use trash cans if they're available. But try to go a step further: Avoid bringing any disposable stuff like water bottles into a park. Right now, our national parks manage 100 million pounds of waste every year—including enough plastic bottles to motivate one well-known activewear company to create a line of upcycled T-shirts made from 160,000 pounds of the stuff, collected from just three parks. "None of us wants to see litter and overflowing trash bins in our parks," Wenzler said. "And we want our parks spending money on rangers and trails, not on trash disposal." (Some national parks are aiming for "zero landfill" status.)

Appreciate the animals from a reasonable distance.
"One of the great things about heading outdoors is experiencing the magic of the wildlife," said Matt Skoglund, director of NRDC's Northern Rockies office. While human‒animal conflicts are rare, you still have to be smart. If you see a bison, moose, or mountain lion at close range, for example, don't try to feed it, approach it, or, for Pete's sake, take a selfie with it. (Bison, one of the biggest attractions for the more than four million tourists who come to Yellowstone each year, have injured more people than any other animal in the park, according to the NPS.) "Give the animal some space, use common sense, and also use your senses," said Skoglund. In other words, stay vigilant while on the trail by carefully observing your surroundings, keeping your ears perked (and definitely earbud-free), and taking note of any whiff of wildlife along the way.
Of course, animals are able to sense you, too. For bears, smell is the sharpest sense, spanning miles, and this means that for the most part, they can (and will) easily avoid you. As a result, while bears (especially grizzlies) inspire particular fear, sightings are rare, Skoglund said. If you do encounter a grizzly at close range, he said, "stay calm and don't run away. Take a few slow steps back and talk calmly to it. It will most likely turn and walk the other way. If not, and it charges you, use your bear spray—the most effective method of deterring an attack."
If you do encounter an ursine, it'll much more likely be a black bear. "There are about 800,000 to 900,000 black bears in North America—that's 15 times the number of grizzly bears," said Stephen Matthew Herrero, professor emeritus of environmental science at the University of Calgary and the author of Bear Attacks: Their Causes and Avoidance. There are hundreds of thousands of encounters between bears and humans each year, but only one to three deaths. (Often the more violent encounters are triggered by dogs surprising or barking at bears; keeping Fido on a leash helps.) "In most cases, as soon as the bear senses you, it will leave," Herrero said. Otherwise, if it shows signs of stress—huffing loudly or swatting a paw at the ground—simply back away slowly. Don't run, or it may instinctively chase you.

Pee responsibly.
If you're on the trail for more than a few hours, you're gonna need to go. For best pee and poop practices, you can check with the park's land manager. Or if you don't relish the thought of having that conversation in person, you can also look online. "Not all regulations will be posted at all places, but there will be site-specific and relevant information on most park websites," said Watts. The general rules of rules of thumb: "If there are facilities, use them," Watts said. If not, and you're in the woods, pee far away from water, campsites and the trail. (One exception: "If you are recreating around or in high-volume running or moving water, like river rafting with overnight camping in designated areas, peeing directly in the water is sometimes the most appropriate," she said.) As for solid waste, "in the backcountry, dig a cat hole the depth of a hand and a half in an organic soil environment," she said. "And don't bury or burn your toilet paper; pack it out in a Ziploc bag." (Sorry, wilderness lovers, but it's just one of the many sacrifices we must make to keep nature intact.)

Wash responsibly, too.
The Leave No Trace Center for Outdoor Ethics recommends that when it's time to wash up, you should carry water 200 feet away from streams or lakes and use small amounts of biodegradable soap (that goes for both your body and your dishes). Also, skip the hand sanitizers and antibacterial soaps—they may seem convenient, but many of these products contain triclosan, a hormone disruptor and a pesticide. Washing with antibacterial soap is no more effective than using regular soap and water to kill germs. Moreover, antibacterial products can contaminate a park's surface waters, as a study by the Great Lakes Network, working in partnership with the U.S. Environmental Protection Agency and other monitoring groups, found after sampling waters from various parks in 2013 and 2014.
Speak out for our national monuments.
You can do even more for the parks you cherish by telling government officials waging an attack on our public lands that you oppose their actions and support our national monuments. President Trump and U.S. Interior Department Secretary Ryan Zinke want to open up America's national monuments to extractive industries that can exploit, privatize, and profit from our lands and waters. And that's far more dangerous than the effects of tourism. "While visitors can have a big impact, the worst impacts on our public lands are caused by industrial and commercial development like oil and gas drilling near park boundaries, or coal-fired power plants in their airsheds," Wenzler said. Raising your voice—and casting your vote—are powerful ways to strike back.
So now, thrill-seeking and rule-abiding outdoor adventurers—get out there!

"It's obviously the main topic of conversation. They are already making contingency plans to relocate some communities," said British sculptor Jason deCaires Taylor, who is currently installing a new piece in one of the archipelago's 26 shallow atoll lagoons.
In a career that began more than a decade ago when he was working as a diving instructor, Taylor has become known for building underwater museums filled with his own sculptures. This latest one, The Coralarium, is as strikingly beautiful as it is eerie, an omen of the island nation's precarious environmental state. Its cube-shaped structure is made of marine-grade stainless steel that reflects the deep blue of the surrounding water. Ocean currents flow through the openings that pierce the structure's surface—openings that also allow marine plants and animals to find their way inside. The roof of the structure stands above the water and is visible from the shore, while the walls and floor are washed by the tides, inviting divers and snorkelers to explore an underwater realm.
"The Raft of Lampedusa" at the Museo Atlántico in Lanzarote, Spain.Jason deCaires Taylor
As did Taylor's submerged concrete VW Bug off the coast of Cancun and his Museo Atlántico in the waters surrounding the Canary Islands—which features sculptures depicting hundreds of selfie-taking tourists, people talking on their phones, and a raft full of marooned refugees—The Coralarium draws attention to the impact of human activity on the oceans. "I very much wanted to tell a story about rising sea levels and the threat it poses to low-lying islands, and obviously, a very clear way to do that is to work above and below the water," the artist explained. "The three tiers of the work connect the three worlds—the aerial, the terrestrial and the subaquatic world—to highlight how these are interconnected and equally dependent on one another."
Often placed in tourist zones, Taylor's sculptures serve to draw visitor traffic away from coral reefs and marine ecosystems that have been damaged by snorkelers and divers while attracting attention to their plight. And since The Coralarium is situated near the Fairmont Maldives Sirru Fen Fushi resort, it targets the sort of visitor who might be able to make a difference. "The people at the hotel are fairly wealthy, to be honest," said Taylor. And with an audience of influential consumers, he pointed out, "this is a good opportunity to bring important issues before people who have some power to change things."
This is a strategy Taylor has used before. The Rising Tide, his 2015 installation of four statues in the River Thames in central London, presented businessman-like figures mounted on horses. Only when the low tide revealed the base of two of the figures did it become apparent that the horses' heads were made up of pieces of oilfield machinery. All four of the provocative statues were clearly visible from Westminster's Houses of Parliament, a gathering place for the lawmakers too often behind policies that drive climate change.
"The Rising Tide," in the River Thames in London.Jason deCaires Taylor
For his next project, Taylor is working with the government of Queensland, Australia, to build an underwater park adjacent to the Great Barrier Reef to bring attention to the catastrophic coral bleaching that's currently threatening the ecosystem. While some of Taylor's previous projects have been works of art as well as artificial habitat for marine plants and animals, the objective of his art here will be more overtly political. "Australia is in huge conflict. It has one of the greatest underwater wonders of the world, but it also has one of the biggest fossil fuel energy industries."
As a debate rages over the proposed expansion of a coal-shipping port on the Queensland coast, Taylor plans to get in the water with sculptures that are "more activist" than his previous work, which he sees as a way of giving the silent seas a voice in the conversation. As he said in a TED talk delivered on a boat in the Solomon Islands in 2015, "I think there's a real danger that we never really see the sea. And if we don't really see it—if it doesn't have its own iconography, if we miss its majesty—then it's a big danger that we take it for granted."

Wild animal selfies drive millions of digital clicks and shares, but these critter photos are not just entertainment for the online masses. They are scientific data collected by camera traps: cameras equipped with a sensor—motion, infrared or light beam—that triggers the shutter when it detects an animal moving by.
These devices let researchers observe wild animals in their natural habitats while largely staying out of their hair, feathers and scales.
In Candid Creatures: How Camera Traps Reveal the Mysteries of Nature, zoologist Roland Kays has collected 613 of the best images from 153 research groups around the world. It's a delightful photo album of wildlife ranging from aardvarks to zebras, with plenty of big cats, bears, primates, elephants and other charismatic critters in between, as well as a comprehensive overview of how camera trap technology is transforming our understanding of their lives.
Camera trapping has been around in some form for more than a century. To create his 1,878 images of a horse in full gallop, photographer Eadweard Muybridge connected strings to the shutters of a dozen cameras, which the horse triggered in sequence by breaking the strings as it ran by. In the late 1880s, Pennsylvania photographer (and one-term Congress member) George Shiras created a camera-and-flash system triggered when a wild animal touched a trip wire. His images won a gold medal at the universal exposition in Paris in 1900.
Fast-forward to 2006, the year photographer George Steinmetz touched off the field's modern era when he created the first digital camera trap while on assignment for National Geographic. In the decade since, cameras have become more durable, memory cards more capacious and batteries more powerful—a trifecta that has ushered in the golden age of the camera trap.
"Modern studies use dozens of camera traps over hundreds of locations to collect many thousands or millions of photographs," Kays wrote. "The camera trap photograph offers a way to measure biodiversity, a testament to life on earth similar to the traditional animal skins and skeletal specimens stored in the collections of our great natural history museums."
Scientists are learning things about even the most avidly observed species from camera trapping, Kays wrote, while generating the perfect means to engage the public on preserving biodiversity, "Data and images are the two most important results of any camera trap study, working together to help in the fight to conserve animals and their habitats.
Sunda Clouded Leopard
A Sunda clouded leopard pauses for his portrait in Borneo's Tawau Hills National Park. "Clouded leopards are forest animals and camera traps most often detect them in evergreen forests," wrote Kays. The species is "tolerant of some level of hunting, as camera traps showed that they continued to survive in an Indian preserve after the tigers, as well as much of the prey, had been overhunted by illegal poaching."

Giant Panda
A pair of pandas stop for a drink in a thicket of bamboo, the plant that makes up 99 percent of this species' diet. "With the panda's skid toward extinction apparently halted, conservationists are now looking for sustainable solutions," wrote Kays. "Camera traps are important tools for monitoring their populations within panda reserves … and hopefully will continue to capture cute photos of these animals long into the future."

African Forest Elephant
An older adult male elephant comes up from a swim in the Echira River in Gabon's Loango National Park. "Camera traps have been more important for studying forest elephants than bush elephants because they are harder to find and watch in person," Kays noted. "Each elephant has a unique appearance, based on size, ear shape and scarring patterns. By placing camera traps in a regular grid across the forests of Loango National Park, Gabon, Josephine Head and colleagues were able to photograph and identify 139 unique individuals, estimating a density of 0.54 animals" per square mile.

Malayan Tapir
The Malayan tapir has the longest snout of the five tapir species and is "Southeast Asia's least known species of megafauna," wrote Kays. To learn more about this species, which is endangered by loss of its preferred evergreen forest habitat, 37 biologists combined images and data representing "52,904 camera trap days of effort across 1,128 locations in 19 nature preserves."

Giant Sable Antelope
A herd of female sable antelope congregates around a salt lick in Cangandala National Park in Angola, which makes the site a good location for a camera trap. "Unfortunately, poachers have also discovered these animal hot spots and are often caught on camera as they patrol by," Kays wrote. "They have seen and destroyed enough camera traps at this site that scientists now have to climb trees and mount them out of sight."

Black Cod
A large adult black cod approaches a baited underwater video station in the rocky reefs of eastern Australia—a "big beautiful fish that also has the misfortune of being delicious," Kays wrote. Overfishing devastated populations of this Australia–New Zealand fish from the 1950s through the 1970s. Its numbers have not bounced back despite more than 30 years of protection. "Out in the deeper waters around rocky reefs some large adults are now seen by snorkelers and photographed by baited remote underwater video stations," Kays continued. "However, young fish are almost never seen, raising concerns over the next generation of black cod."

Tasmanian Devil
A Tasmanian devil runs away from a bird carcass that served as its recent meal. Found only on the Australian island of Tasmania, the devil population has plunged 90 percent since 1996 owing to a unique, transmissible facial cancer. But camera trapping at one location has buoyed hope for the species, Kays wrote. "[D]evils at Freycinet National Park suffered only a small initial population decline when the cancer first arrived," he wrote, "but the population has bounced back. The tumors can be identified in good camera trap photos, allowing officials to see that it was never common in the park, and that it has declined since 2006."

Giant Pangolin
A giant pangolin rears up, showing its fierce claws. Its heavy tail acts as a counterbalance, allowing it to run with very little weight on its front feet, keeping its claws sharp for digging into termite or ant mounds.
Rampant poaching of pangolins for their scales, which command large sums on China's black market, has threatened the species' survival. Along with campaigns to reduce public demand for pangolin parts and intensified policing of the illegal wildlife trade, Kays wrote, conservationists "on the ground in African and Asian forests [are] patrolling for poachers and using camera traps to try to determine where the pangolin populations persist."

Bornean Orangutan
A baby orangutan crosses a gap in the forest to catch up with its mother. Conversion of forests to palm oil plantations has been a major factor in Bornean orangutan population declines. "The species is threatened by habitat destruction and by selective logging," Keys wrote. "Camera trap surveys can map where these monkeys still roam, helping to target conservation efforts."

Western Gorilla
The world's largest primate, weighing up to 600 pounds, the western gorilla is critically endangered thanks to poaching, Ebola epidemics and loss of its lowland rainforest habitat. This silverback male gorilla encountered a camera trap in Gabon. "Tracking the declines and recoveries of gorilla numbers over these remote areas is challenging and many traditional methods have since been found to be unreliable or too difficult to scale up," wrote Kays. "A few recent studies with camera traps suggest that they could be a useful tool to help count and protect gorillas," in part because "gorillas have unique faces and can often be identified from photos."

Naruto, a now-famous monkey known for taking a "selfie" that prompted an unprecedented copyright lawsuit, has another chance at claiming ownership over his image as People for the Ethical Treatment of Animals (PETA) has filed an appeal to the United States Court of Appeals for the Ninth Circuit.
The images in question were taken in 2011 by Naruto, a then–6-year-old male, free-living crested macaque in Indonesia. Photographer David J. Slater had left his camera unattended in an Indonesian forest, which allowed Naruto to take several photos of himself. Slater and his company, Wildlife Personalities Ltd., which both claim copyright ownership, published the photos that Naruto indisputably took. PETA sued, claiming that Naruto was the author of the photos and that Slater had infringed on Naruto's copyright.
Disappointingly, in January, a federal judge dismissed the monkey selfie suit, finding that a non-human animal could not own a copyright.
"In every practical (and definitional) sense, he is the 'author' of the works," argued PETA, in the appeal brief. "Had the Monkey Selfies been made by a human using Slater's unattended camera, that human would undisputedly be declared the author and copyright owner of the photographs. Nothing in the Copyright Act limits its application to human authors. … [P]rotection under the Copyright Act does not depend on the humanity of the author, but on the originality of the work itself."
PETA's brief also emphasizes that the Copyright Act should be interpreted broadly and was intended to expand to include new forms of expression unknown at the time that it was enacted.
If this lawsuit succeeds, it will be the first time that a nonhuman animal has been declared the owner of property rather than a piece of property himself or herself. It will also be the first time that a right has been extended to a nonhuman animal beyond just the basic necessities of food, shelter, water and veterinary care. In our view, it is high time.
"The fact that copyright ownership by an animal has not been previously asserted does not mean that such rights cannot be asserted," PETA wrote. "[I]nsofar as the issue of non-human authorship has been considered by this court, it remains an open question. The only requirement articulated by this court so far is that the 'author' be of this world. And Naruto certainly meets that requirement."
PETA is seeking the court's permission to administer and protect Naruto's copyright in the "monkey selfies," without compensation, with all proceeds to be used for the benefit of Naruto and his community.
