1 . The cry of the fishing cat sounds like the quack of a duck, and the rest of this midsize cat also enables it to hunt in the water. Its streamlined head is perfect for moves in the mangrove swamps (红树林沼泽地) and wetlands of South and Southeast Asia, and its pointy ears even fold (折叠) down when it jumps into deep water. The short and strong tail helps control its direction. The extra-thick coat keeps it warm and dry while swimming.

“I found fishing cats to be very ingenious,” says Tiasa Adhya, co-founder of The Fishing Cat Project, a research and conservation group based in eastern India. Her research recently showed that the animal has two methods of catching fish. In deep waters, the cat stays still on the banks for hours before jumping into the water for the kill. In shallow (浅的) waters, though, the cat actively drives the fish out of their hiding places by moving about with heavy steps.

Now the fishing cat is facing another challenge: humans. The world has lost almost 90 percent of its wetlands since the 1700s, with Asia suffering the greatest loss. These days, industrialized fish farming, pollution and other human behaviors have destroyed the living condition of freshwater fish and set fishing cats against farmers, as the hungry cats steal farmed fish, and the farmers get even with them (报复). Once found along river systems from Pakistan to Vietnam, the cats have disappeared from large areas of their range.

Researchers are testing new methods, including the commercial launch (商业化推出) of a type of native rice variety. Depending on nutrients (营养物) washed in by rains rather than on chemicals, the rice creates living space for the fishing cat and its food. The idea is that in healthy lakes where there is plenty to feed fishing cats and fishermen alike, killings will be unnecessary. “Nobody takes a loss,” Adhya explains, “when somebody takes a fish.”

2 . As a child, Cruz Avila walked through the forest every day in central Mexico’s Amanalco-Vall de Bravo Basin. She would pick wood and medicinal plants. She also learned to find birds and identify the different trees near her home. Avila learned that listening to a waterfall is a good medicine for the soul and the body.

Several months ago, she and other residents decided to make these walks an attraction for tourists. Their goal is to create a source of income, preserve the forest and support responsible medicine for the soul tourism. In 2021, Avila and other community members attended training as nature guides.

In recent years, residents of the forest communities have suffered from tourism that’s not environmentally sustainable (可持续的). In early April 2022, the communities officially presented their alliance (联盟). One of the people presenting it was Avila, and her voice echoed (附和) the feelings shared by many who are part of this project. “To us, forests are our home,” she said. “We want to take care of them as we take care of our home. We invite hikers and tourists to come to see our house, to get to know and enjoy this place with respect and care.”

Avila said her community has developed a sustainable tourism plan based on hiking and workshops. They also plan to have a viewing platform ready by 2023.

Avila said she plans to start promoting her hiking project, “I’m going to take visitors to a place called El Caballero, and halfway through, with the other neighbors, we’ll offer them a workshop on making pulque and bread,” she said. Pulque is a drink made from a plant that grows in the region.

She believes the tourism project will receive support from visitors. She thinks it will be especially popular with those who are eager to help protect the forests and want to learn about forest communities.

3 . Vishwanath Mallabadi Davangere has a unique talent for turning abandoned items into amazing works of art. From metal and plastic to old devices and circuit boards, Vishwanath selects only the finest “good stuff” with potential for transformation.

Vishwanath’s father was a well-known sculptor and painter, but he had hopes of his son becoming a doctor. But Vishwanath had other ideas. He was fascinated with upcycling second-hand objects from a young age, and decided to pursue a Bachelor of Fine Arts in Applied Art. Even as a high-level administrator at Wipro, working in Talent Transformation, Vishwanath wouldn’t shake his passion for eco-art. In his free time and on the weekends, he devoted himself to experimenting with e-waste and creating one-of-a-kind masterpieces before retiring two years ago.

With India facing a growing e-waste crisis, producing 10.1 lakh tonnes in 2019-20 with only 22.7% recycled, Vishwanath’s passion for recycling is more important than ever. As he learned more about the harm e-waste was causing to the environment, he took his art to the next level creating paintings and sculptures that spread awareness about this urgent issue.

From computer keyboard keys to data cards and even wristwatch parts, Vishwanath has transformed over 500 pieces of e-waste into amazing pieces of art! He has created a six-foot-tall sculpture, eco-jewellery and even wearable art for a fashion show. One of his masterpieces—an awesome landscape—was inspired by Vincent van Gogh’s The Starry Night.

In just a few short minutes, he can turn pieces of e-waste into great pieces of jewellery. When it comes to sculptures, the process might take weeks or even months. But it’s all worth it because sustainable initiatives and upcycled art are fashionable these days. Companies everywhere are looking to adopt a more sustainable culture, and Vishwanath’s art is the perfect addition to any eco-friendly office or home.

4 . Finding a California condor in the wild would be the most unusual treat. perhaps even more unusual than finding a wolf in Yellowstone National Park. In fact, the wolf was what opened my eyes to the fact that humans could bring an animal back to the place where it had disappeared.

In 1987, there were only 27 California condors left, none of which were in the wild, only in captive breeding programs, It was those breeding programs that contributed to their population rise, enough that by 1991 some of them could be freed into the wild.

Still, the hope of seeing a California condor, which remains an endangered species, is very low, let alone getting a photo of one. California condor population dropped mostly due to human factors, such as poaching and living areas destruction-these are challenges California condors still face today.

Although this is just a bird’s-eye view of the challenges California condors face and there are many others, it is part of why the opportunity to work with the US Fish and Wildlife Service team and their partners helping their recovery is so special to me as a photographer. I am not only able to photograph the birds in their wild living areas, but also understand and record how difficult the work is of those people on the front lines of the protection.

I am grateful for the work of the team, and my hope is that California condor population will continue to rise allowing future generations an opportunity I never had when I first got here-to look to the sky and see one flying around.

7 . For the past 13 years, Martin Burrows has been working as a long-distance truck driver. Spending up to five nights a week on the road can be a lonely business, leaving him with plenty of time to notice his surroundings. “I kept seeing more rubbish everywhere and it was getting on my nerves. I decided I had to do something about it,” he says. One day, he stopped his vehicle, took out a trash bag and started picking up the garbage. The satisfaction after clearing a small area was remarkable.

Before his time on the road, Burrows spent over two decades in the military as a vehicle driver. His service saw him stationed throughout Europe and also on tours in Afghanistan. After returning to civilian life, he was diagnosed with PTSD (创伤后应激障碍) and had a mental health crisis in 2017. His involvement in fundraising for Help for Heroes led him to meet a man who used model-building as a distraction from PTSD. Burrows realized that his act of roadside cleanup had a similar calming effect on his mental well-being.

By 2019, Burrows had begun using his free time on the road to regularly clean up garbage. A passerby encouraged him to set up a Facebook group, which he called Truckers Cleaning Up Britain. “I was worried I’d be the laughing stock of my town for putting videos and photos up of me cleaning but people started to join,” he says. “I was amazed. The local council stepped in and gave me litter-picking supplies and we’re up to almost 3,000 members now.”

Since truckers are so often on the move, the Facebook page acts as a means of raising awareness rather than a platform for organizing cleanups. Burrows expressed his intention to continue the cleanup efforts as long as his physical condition allowed, as he still found joy in the process.

8 . The 16-year-old Australian Shalise Leesfield couldn’t think of a better creature to meet than a gray nurse shark when diving off the coast. “I know how scary they can look, but I promise they are the sweetest animals ever,” she says. But they are under threat.

Leesfield is working with Cate Faehrmann, member of parliament (议会) and marine spokesperson for the Australian Greens party in New South Wales, to legalize protection of the sharks. Faehrmann says that she’s proud to have worked with Leesfield. “Shalise is part of a new generation of campaigners speaking up for the environment and our future is a lot brighter as a result of their passion and determination to save our planet and our precious wildlife.”

For someone who hasn’t yet left high school, this sounds like an impressive achievement, but Leesfield’s track record in conservation goes beyond protecting gray nurse sharks. Aged 11, after noticing the damage plastic pollution can do to the marine environment, she started a campaign that called for fishing line collection bins to be set in her local area to reduce ocean pollution. It resulted in a government environmental grant worth more than $48,000.Since then, she has founded “Shalise’s Ocean Support” which aims to inspire people to take care of the environment, and started a “Plastic Free Schools” website which advises teachers and students on reducing school waste.

Leesfield’s devotion to the cause comes from a deep love of the ocean that grew from her experiences of diving. “Falling in love with the sea made my passion grow and made me stand up for what I really love,” she says.

She believes that the younger generation needs to get out of the mindset that saving the environment is something that should be “left up to the adults”. “We are the ones that will take over the Earth and the ocean,” she says.

9 . Sputnik, the world’s first satellite, was sent up in October 1957. About 100 trillion human-made objects are circling the planet now! The jaw-dropping number was provided by an international team of researchers writing in the journal Science. There are 9,000 active satellites in space, the scientists report. That could grow to more than 60,000 by 2030.The rest of that 100 trillion figure includes everything from used-up rockets and stray bolts(螺栓) to metal pieces and paint chips.

Don’t think a tiny piece of debris(碎片) is harmless. Traveling at 17,500 miles per hour, it can strike a spacecraft hard. The International Space Station is dotted with dents(凹陷) and holes. Astronauts often take shelter in an attached spacecraft to wait out a passing group of space pieces. That way, if the station is severely damaged, they can escape out in a hurry.

For years, this waste has formed an ever-growing mass near Earth. All of these pieces will eventually fall to Earth and burn up in the atmosphere. But we’re replacing the waste more quickly than it’s falling.

The mess we’ve made in space is like the mess we’ve made in the oceans. We’ve had centuries to pollute the oceans. But it has taken just decades for us to do the same in space. That’s why the Science authors include experts in satellite technology and in ocean plastic pollution. Cleaning up space has a lot in common with the challenges of dealing with environmental issues in the oceans.

In March 2022,170 countries signed a global plastics treaty(条约) in the United Nations. This is an agreement to throw away less plastic in the oceans and get rid of what’s already there. There could be similar rules for how many pieces a launch can create. Old satellites could be taken out of space. And technologies could be developed for cleaning up the waste.
