As people across the globe stay home to stop the spread of the new coronavirus, the air has cleaned up, albeit temporarily. Smog stopped choking New Delhi, one of the most polluted cities in the world, and India's getting views of sights not visible in decades. Nitrogen dioxide pollution in the n ortheastern United States is down 30%. Rome air pollution levels from mid-March to mid-April were down 49% from a year ago. Stars seems more visible at night.
People are also noticing animals in places and at times they don't usually. Coyotes have meandered along downtown Chicago's Michigan Avenue and near San Francisco's Golden Gate Bridge. A puma roamed the streets of Santiago, Chile. Goats took over a town in Wales. In India, already daring wildlife has become bolder with hungry monkeys entering homes and opening refrigerators to look for food.
When people stay home, Earth becomes cleaner and wilder.
"It is giving us this quite extraordinary insight into just how much of a mess we humans are making of our beautiful planet," says conservation scientist Stuart Pimm of Duke University. "This is giving us an opportunity to magically see how much better it can be."
Chris Field, director of the Stanford Woods Institute for the Environment, assembled scientists to assess the ecological changes happening with so much of humanity housebound. Scientists, stuck at home like the rest of us, say they are eager to explore unexpected changes in weeds, insects, weather patterns, noise and light pollution. Italy's government is working on an ocean expedition to explore sea changes from the lack of people.
"In many ways we kind of whacked the Earth system with a sledgehammer and now we see what Earth's response is," Field says.
Researchers are tracking dramatic drops in traditional air pollutants, such as nitrogen dioxide, smog and tiny particles. These types of pollution kill up to 7 million people a year worldwide, according to Health Effects Institute president Dan Greenbaum.
The air from Boston to Washington is its cleanest since a NASA satellite started measuring nitrogen dioxide,in 2005, says NASA atmospheric scientist Barry Lefer. Largely caused by burning of fossil fuels, this pollution is short-lived, so the air gets cleaner quickly.
Compared to the previous five years, March air pollution is down 46% in Paris, 35% in Bengaluru, India, 38% in Sydney, 29% in Los Angeles, 26% in Rio de Janeiro and 9% in Durban, South Africa, NASA measurements show.
"We're getting a glimpse of what might happen if we start switching to non-polluting cars," Lefer says.
Cleaner air has been most noticeable in India and China. On April 3, residents of Jalandhar, a city in north India's Punjab, woke up to a view not seen for decades: snow-capped Himalayan peaks more than 100 miles away.
Cleaner air means stronger lungs for asthmatics, especially children, says Dr. Mary Prunicki, director of air pollution and health research at the Stanford University School of Medicine. And she notes early studies also link coronavirus severity to people with bad lungs and those in more polluted areas, though it's too early to tell which factor is stronger.
The greenhouse gases that trap heat and cause climate change stay in the atmosphere for 100 years or more, so the pandemic shutdown is unlikely to affect global warming, says Breakthrough Institute climate scientist Zeke Hausfather. Carbon dioxide levels are still rising, but not as fast as last year.
Aerosol pollution, which doesn't stay airborne long, is also dropping. But aerosols cool the planet so NASA climate scientist Gavin Schmidt is investigating whether their falling levels may be warming local temperatures for now.
Stanford's Field says he's most intrigued by increased urban sightings of coyotes, pumas and other wildlife that are becoming video social media staples. Boar-like javelinas congregated outside of a Arizona shopping center. Even New York City birds seem hungrier and bolder.
In Adelaide, Australia, police shared a video of a kangaroo hoping around a mostly empty downtown, and a pack of jackals occupied an urban park in Tel Aviv, Israel.
We're not being invaded. The wildlife has always been there, but many animals are shy, Duke's Pimm says. They come out when humans stay home.
For sea turtles across the globe, humans have made it difficult to nest on sandy beaches. The turtles need to be undisturbed and emerging hatchlings get confused by beachfront lights, says David Godfrey, executive director of the Sea Turtle Conservancy.
But with lights and people away, this year's sea turtle nesting so far seems much better from India to Costa Rica to Florida, Godfrey says.
"There's some silver lining for wildlife in what otherwise is a fairly catastrophic time for humans," he says.

A rare species of tortoise known as 'Batagur Baska' laid 21 eggs at Tortoise Breeding Centre at Karamjal Wildlife Breeding Centre of the Sundarbans under Khulna district.
Md Azad Kabir, in-charge of the breeding centre, said Batagur Baska laid 21 eggs on Friday morning on the edge of a pond.
The eggs look like that of ducks, he said, adding that they were trying to hatch these eggs naturally by putting it on sand and supervising the temperature constantly.
It will take 65-67 days to hatch the eggs, Kabir added.
According to information from the Forest Department, Batagur Baska laid a total of 197 eggs since 2017.
Altogether 110 tortoises were hatched at the Karamjal Wildlife Breeding Centre until 2019, while three tortoises among those died in Indian and Bangladesh territories, the sources said.
The Tortoise Breeding Centre was set up in 2014 in Karamjal and eight rare tortoises of Batagur Baska species were released in a pond.
Mohammad Belayet Hossain, divisional forest officer of the Sundarbans East Zone, said there are 252 Batagur Baska tortoises at the breeding centre right now. Of them, 23, including four female ones, are adult.
Ten more tortoises of this species will be released in the Sundarbans, he added.
For the fourth time, near-extinct river turtle ‘Batagur Baska’ laid 35 eggs at a wildlife breeding centre in Karamjal of East Sundarbans on Tuesday.
Forest Department is trying to hatch eggs through natural incubation (keeping them in sand) process, said Azad Kabir, officer-in-charge of the breeding centre.
He said the process would take 65-67 days.
Batagur Baska is one of the most critically endangered turtles in the world and can only be found in the wild in the mangroves of Bangladesh and India.
In 2017, two turtles laid 63 eggs of which 57 hatched. The next year, two turtles laid 46 eggs, of which 24 hatched. Last year, one turtle laid 32 eggs and all of them hatched.
