2 . Overlooking the Davis—Gant Varsity Soccer Field, a bed of overturned soil waits for further development. In a few years, this area will become a natural habitat and a playground for animals and residents. This peaceful area didn’t appear naturally, but through planning and action taken by Catlin Gabel’s Tiny Forest project launched by teacher Patrick Walsh.
Forests typically take hundreds of years to mature, with four stages of growth. “Tiny forests flatten out time through the planting of all four layers (层),” Walsh explained. The end result is a fast-growing, native forest in about 20 years. Over 600 plants from 43 species will be planted in the tiny forest, the first one in Oregon.
Walsh was inspired to build a tiny forest after hearing about this idea, which emerged in Japan and has taken hold in North America. He shared his vision with seniors in his class. The seniors researched tiny forests and made a proposal resulting in Clean Water Services donating 60 trees and $5,000 from the National Oceanic and Atmospheric Administration. Armed with these resources, Walsh and the students started working. “Something I didn’t really expect was the outpouring of students’ enthusiasm. Seeing students from all grades volunteered to contribute to the ‘dirty work’ really blew me away,” Walsh said.
Senior Megan Cover has been at the school since the first grade. “I’ll graduate after working on this project, which is surely sad, but it’s really rewarding and great to be a part of this project and to do my bit. We’re creating this educational space for many young kids,” Cover said.
Walsh summed up his goal of the project, which is to build a place where students can enjoy and learn about nature. “The forest will obviously not solve climate change, but it will deserve the efforts if the kids think about climate change and remember the importance of reforestation and trees when they look outside at the forest.”

3 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.
The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.
As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

6 . With needle-like teeth and sharp pointed nose, a gray nurse shark isn’t a creature that most people would want to meet. But Shalise Leesfield isn’t one of them.
The Australian teenager couldn’t think of a better creature to meet when scuba diving off the coast of South West Rocks, near her home in Port Macquarie, a coastal town north of Sydney.
“Many people say gray nurse sharks look frightening, but I think they are the sweetest animals ever,” she says.
The slow-moving sharks, which like to stay near the sea floor in warm, shallow waters, are — for the most part — harmless to humans. But the gray nurse shark is under threat. Populations have fallen and habitats have been lost due to ocean warming and human development, according to the International Union for Conservation of Nature (IUCN), which lists the species as seriously endangered.
One area where they can still be seen is Fish Rock, an underwater cavern (洞穴) with a unique ecosystem, 40 miles up the coast from Leesfield’s home. But fishers are allowed access within 200 meters of Fish Rock. This is leading to a drop in the number of gray nurse sharks and increased pollution, says Leesfield. She wants to enlarge the no-fishing area, establishing a protected zone.
With Leesfield’s efforts, the area has been nominated as a Hope Spot, which is part of the mission Blue program launched by famous oceanographer Sylvia Earle that identifies places as critically important to the ocean’s health and supports protection.
“When people think about Hope Spots, they think about Sydney Harbour or the Great Barrier Reef. So to get Fish Rock up on that list is just such incredible news,” she says.
Now, Leesfield is working with politician Cate Faehrmann, marine spokesperson for the Australian Greens party in New South Wales, to legalize protection of the sharks and make the no-fishing zone protected by the law.

9 . Washing machines and fridges will be labelled with their carbon footprint as part of efforts to promote greener products and bring down carbon emissions (排放).
UK government want to introduce a system in which products would be labelled to show how much greenhouse gases had been given off while making the product. Officials favour a system in which labels describe the product’s emission figure along with a ranking, such as from A to G. A rating of A would represent a “zero emission” product.
In consultation papers published earlier, the government said: “The combination of the emissions figure and ranking system could give a simple way to find out the best products, as well as the raw data needed to make more detailed comparisons.” Officials hope the labelling would encourage people to buy greener products, helping to bring down carbon emissions.
The government has not set out which products the emission figures would apply to, but it is likely to eventually apply to products whose production process involves significant emissions, such as heavy goods involving steel or plastic.
The proposal is among several steps by the government to encourage UK companies to cut their emissions, alongside wider measures to boost clean energy supplies.
Officials are also considering introducing new import taxes to protect UK factories from being affected by cheap imports from competitors. Under the proposals, imported goods without costs for going green would face extra taxes. The potential so-called carbon border taxes are aimed at protecting areas such as steel and chemicals.
Matthew Germain, an expert in British Environmental Law, said the measures would mean the UK was “at least keeping step with the European Union (EU)”. The EU reached a deal in December of 2022 to charge carbon taxes on imports of iron and steel, and electricity. Countries will not be affected if they have same climate change policies to the EU.

10 . The endangered pandas in the Qinling Mountains might face a new threat: the loss of their food, bamboo, which makes up 99% of their meals.
Adult pandas spend most part of the day eating bamboo and have to take in at least 40 pounds a day to stay healthy. However, a new study published in Nature Climate Change warned that they may soon find their food gone because most of the bamboo in the Qinling Mountains might disappear by the end of the century as a result of rising temperature worldwide.
A team made up of researchers from Michigan State University and the Chinese Academy of Sciences has studied the effects of climate change on the bamboo in the Qinling Mountains. They have found that bamboo is very sensitive to climate changes. “80% to 100% of the bamboo would be gone if the average temperature rises 3.5 degrees worldwide by the end of the century,” said Liu Jianguo, one of the report’s authors.
He added, “This is how much the temperature would rise by 2100 even if all countries will keep their promises in the Paris Agreement. But you know what is happening all around the world.”
In recent years, China has been trying its best to protect the endangered pandas by setting up more and bigger natural reserves.
“But it is far from enough and the endangered pandas need cooperation from the rest of the world, because their future is not just in the hands of the Chinese,” said Shirley Martin from the World Wildlife Fund but not a member of the team.
The Qinling Mountains, in the southwest of China, are home to about 260 pandas. That is about 13% of China’s wild panda population. In addition, about 375 are living in research centers and zoos in China.
