1 . An adult African elephant consumes about 223 liters of water and 3,080 pounds of roots, grass and fruit daily. That’s like having 634 cans of soda and 1,200 hamburgers every day. This keeps them moving thousands of miles across Africa each year. Elephants usually migrate between March and May. Females live in groups with their children, and quickly run out of the food supply. They hit the road in search of food. Male elephants live alone, so they don’t use resources as quickly as the females. Instead, they migrate during their mating cycle. When the females pack their trunks, so do the males.
During migration, elephants face short water supplies and extremely high temperatures. But people are their number-one problem. Poachers (偷猎者) kill 35,000 elephants each year for ivory. Many African farmers build fences (栅栏) to protect crops and cattle, which might block regular migration paths. Traffic roads affect elephant migration, too. During one study of 28 elephants in Central Africa, only one female crossed an unprotected road.
Scientists, wildlife organizations and governments cooperate to find solutions for Africa’s elephants. “To unlock the secret of where elephants move and how they move, we place collars (项圈) with a satellite unit inside,” Dr. Michael Chase says. GPS collars help map which routes elephants use most so that countries can establish protected elephant passages.
Locals come in as well. James Isiche, East Africa Director of the International Fund for Animal Welfare says, “We have got the community on our side by a project; they’ve agreed to partner with us to conserve elephants.” The local community run wildlife parks to attract tourists. “This project helps us take care of both the wildlife and our cows,” says Sikira, a tribal elder in Maasai, Kenya. Protecting elephant migration routes allows these gentle giants to survive.

3 . In the northernmost edge of Colombia sits the coastal town of Acandí. Access to the town is only by water or air; there is no road that leads there. The residents there are faced with the struggles of balancing livelihoods while protecting biodiversity.
In the past, traditional community fishing methods, passed down by the elders, focused on the reasonable fishing and management of resources. However, the introduction of large-scale trawling vessels(拖网渔船) decades ago gradually depleted the area’s fishing resources, leading to damage to marine(海洋的) life seriously.
Jesús Antonio Julio Cuestas, who serves in the region’s conservation and management of marine resources, stresses the bad impact of these developments and calls for new fishing techniques. “Fishing and conservation co-exist as long as we have good management practices and reasonable use of our fishing resources,” says Cuestas. He and other officials actively monitor fishing activities in Acandí. Each morning, they visit the fish markets to gather data on fishery resources—including prices and sizes—to monitor the state of the local fishing industry.
Along with Cuestas, the fishers work to reduce their impact on the marine ecosystem. By changing fishing methods and adopting new practices, they aim for a more balanced approach to fishing. “This year the local fishermen have not used the trawl net s that were causing the death of the leatherback sea turtles,” explains Cuestas proudly. Changes include the efforts of boats to protect the seagrass that serves as feeding grounds for marine life and an end to fishers throwing net s where turtles lay their eggs.
This marine reserve in Acandí, Cuestas believes, is their greatest treasure. He attaches great importance to working together with local residents to improve the quality of life while preserving the marine ecosystem. By doing so, he imagines a picture where individuals from the fishing community can pursue various careers, such as engineers or lawyers, proudly stating that they are the products of the fishing tradition in Acandí.

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.

5 . A lot of people find it difficult to do exercise regularly, even though they know it’s good for their physical and mental (身心上的) health. Yet keeping on a workout routine doesn’t necessarily go to the gym or run around your neighborhood. Gardening is a great example of a popular hobby that can be used as a workout.
Nashville resident Tom Adkinson, 72, is on board with the idea of gardening to stay fit. He has three gardens, which he uses primarily to grow tomatoes, sweet banana peppers and okra. Like traditional exercise, Adkinson does a lot of preparation before gardening, and then he spends hours watering and weeding (除草) all three gardens, involving bending and stretching, which he compares to performing garden yoga.
“It is wise of Adkinson to do so. Even though gardening may not appear difficult, using the body in new ways can make you hurt if you don’t warm up beforehand,” said Zeller, who teaches at the Rutgers Cooperative Extension of Cape May County in New Jersey.
Working in your garden just two hours a week could improve your mood. And the communal gardening, which is done by a number of people as a group in communities and schools, provides social benefits that can reduce stress and help fight against loneliness and even dementia according to studies.
“With all these benefits, gardening for fitness will be a trend (趋势) in the coming year,” announced Mandal, CEO of the fitness coaching app Future, “Our users at Future have already been asking their coaches to add gardening and landscaping activities into their routines because it’s easy to get and fit into their lifestyle.”

7 . A compost (堆肥) program at the Wesley School in Los Angeles is helping kindergarten through eighth grade students to teach them ways to solve human-driven climate change. For the past year, 5, 200 pounds of food waste from the school has gone into compost containers rather than a landfill where it would just break down and produce planet-warming gases.
The school workers could have easily thrown the food waste into a city-provided green bin (垃圾箱) . But taking it out of sight, which would have been easier, would have missed the point, says science teacher Johnna Hampton. “When it’s invisible like that, they don’t see it, but they know it doesn’t sink in (心安) .”
When sixth grader Finn saw the finished compost pile, it sank in. “That’s my orange chicken in there,” he says. “That’s not just like any food. Somewhere in there is my food.”
The school will use the compost on plants around campus. Some will be offered to families that want to use it at home, and whatever is left will be donated.
Fifth grader Sloan felt so encouraged by the school’s compost program she decided to take climate action outside of school. Along with several other fifth graders, Sloane says, “We did a lemonade stand at our friend’s house and we made over $200, and we donated it.” They also helped create a petition (请愿) to replace the plastic forks and spoons in the school cafeteria with compostable ones.
Fifth grader Kingston was excited to learn his food waste will help grow new food on campus. “It feels good that you’re doing something that helps the planet, instead of just sitting and watching it get destroyed,” he says.
Jennifer Silverstein, an expert on climate, says the school’s compost program checks a lot of the boxes for effective, positive climate education to help youth understand the crisis of human-caused climate change.
