After years of debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and moved to the park. By 2016, the Yellowstone wolf population had grown to more than 170.
Gray wolves once were seen here and there in the Yellowstone area and other parts of United States, but they were gradually displaced by human development. By the 1920s, wolves had 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 ate large amounts of plants, which reduced plant diversity(多样性)in the park. With the disappearance of gray wolves, coyote(草原狼)populations also grew quickly. The coyotes killed a great number of red foxes in the park, and completely drove away the park’s beavers(河狸).
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 were against the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years thinking up a plan to reintroduce the wolves. 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.

【推荐3】"What kind of rubbish are you?" This question has brought about complaints over the past months in Shanghai. On July 1st, 2019, the city introduced strict trash-sorting rules. Residents must divide this waste into four separate groups and throw it into specific public bins.
Shanghai is faced with an obvious environmental problem. It produces 9 million tons of rubbish a year, and the number is rising quickly. Like other cities in China, it has relied on trash pickers to pick out whatever can be reused. But as people get wealthier, fewer of them want to do such dirty work. The waste, meanwhile, just keeps piling up.
Many people appear to be bothered by the rules. Rubbish must be divided according to whether it is food, recyclable, dry or hazardous (有害的), the differences among which can be complex and confusing. Some have complained that they must put food waste straight in the required public bin, forcing them to tear open plastic bags and throw it by hand. Most annoying is the short scheduled time for throwing trash, typically a couple of hours, morning and evening. This means that people all go at the same time and anyone can keep an eye on what is being thrown out; no one wants to look bad.
People who fail obey the rules could be hit with fines of up to 200 yuan. For repetitive violators, the city can add black marks to their credit records, making it harder for them to get bank loans or even buy train tickets. However, citizens support the idea of recycling in general and say a tough campaign is necessary. "Slowly people will get used to it," says Li Chongjin of Fudan University.
