The world consumes hundreds of billions of single-use plastic bags each year. They are difficult to recycle, wasteful and damage the nature. Environmental activists want to ban plastic bags or—as many communities have done —charge a fee for them. But the plastic bag industry defends their use, saying people reuse plastic bags, and industry officials argue recycling is a matter of personal responsibility and should not be forced.

    City officials say New Yorkers use 5.2 billion plastic bags each year. They are offered free with nearly every supermarket, or convenience store purchase. Many people like them, even if they sometimes feel guilty about using them. But what happens to those bags after they've been used in a huge environmental problem. They are found on beaches. They are caught in trees. They are swallowed by marine life.

    Plastic bags are made of petroleum products and natural gas, and do not biodegrade (分解). And they are difficult to recycle. So New York City spends nearly $ 10 million dollars a year to send 100—thousand tons of plastic bags to landfills out of state.

    In Washington, D.C., a five percent charge on all single-use bags led to about a 60 percent reduction and in Los Angeles County in California , a 10 cent charge on single-use bags led to a 95 percent reduction. With a 10 cent charge on bags, customers are much more likely to stop and think about whether they need a bag or not. And that's really all that these laws are doing.

    At the beginning of the century there was a big farm called Hollywood Ranch. It was near Los Angeles in California. A few years later Hollywood was one of the famous places of the world. From 1910s to the 1950s Hollywood was the film center of the world. Every family knew the names of its film stars Charlie Chaplin, Grete Garbo, Bergman and hundreds more.

    The reason why people went to Hollywood to make films was the sun. At first people made films in New York on the east coast of the United States. But then they heard about Los Angeles where there are 350 days of sun every year. As they made all the films by sunlight, the west coast was a much better place to work.

    Also near Hollywood you can find mountains and sea and desert. They did not have to travel far to make any kind of film.

    When TV became popular in the 1960s, Hollywood started making films for television. Then in 1970s they discovered people still went to cinema to see big expensive films. After twenty years they are still making films in Hollywood and people watch them all over the world.

    Forests are always losers at the Olympics, and that's unlikely to change anytime soon.

    For the winter games in PyeongChang, South Korea, virgin forest was destroyed on Mount Gariwang to accommodate ski runs. For the 2022 Winter Olympics in Beijing, a ski run is set to wipe out part of the Songshan National Nature Reserve. And let's not forget the 240 acres of Atlantic Forest that were leveled for the 2016 games in Rio de Janeiro to make way for a golf course.

    For the upcoming Tokyo games, environmental and human rights advocates have been raising alarms about the use of tropical (热带的) wood to build the New National stadium. Activists have fought against such environmental destruction. The damage is often permanent, threatens endangered plants and animals and in some cases, causes conflicts with native people. But frequently the country's organizing committee, and the International Olympic Committee (IOC) have found ways to make it reasonable — despite a paragraph in the Olympic Charter (宪章) that states that the IOC's role is to "encourage and support a responsible concern for environmental issues".

    "As it stands now, the IOC has little authority over a city's local organizing committee, which finally plans the event, " Chappelet, professor of public management at the University of Lausanne, told Earther. "Even if the IOC is dissatisfied with the way host cities have prepared for the games, they have no built-in systems to watch them so that they strictly follow the Olympic Charter." The only thing they can do if they're not happy is to withdraw (= take back) the right to organize the game. "But the IOC could include more enforcement (执行) systems into the contract they make with the host city," he added. That contract must be signed and obeyed by everyone and those who break it must be fined.

    Boykoff, the author of several books on the Olympics, suggested a similar solution. "The IOC could insist that host cities take their ecological (生态的) promises into account first, but instead they look the other way, time and time again," he said.

    Scientists have recreated a 1985 study of birds in Peru that shows climate change is pushing them from their natural environment. Thirty years ago, researchers studied more than 400 kinds of birds living on a mountainside in Peru. In 2017, researchers looked again at the bird populations. They found that almost all had moved to higher places in the mountain. Almost all had decreased in size. And, the scientists say at least eight bird groups that move to the higher altitude had died out completely.

    Mark Urban, director of the Center of Biological Risk at the University of Connecticut, said this recent study was the first to prove that rising temperatures and moving to avoid them can lead to extinction.

    In 1985, Fitzpatrick, director of the Cornell Laboratory of Ornithology, and a team of scientists established a camp alongside a river running down a mountainside in southeastern Peru. He wanted to document where tropical bird groups lived. His team spent several weeks using nets to catch and release birds. They kept detailed notes of birds they caught, saw or heard. In 2016, Fitzpatrick passed his notes, photos and other records to Benjamin Freeman. Freeman who has been researching tropical birds for more than 10 years set out in August and September of 2017 to copy Fitzpatrick's study. His team used the same methods, searching the same places in the same time of year.

    Freeman said that the birds moved an average of 98 meters further up the mountain, believing that temperature is the main cause of the birds' movement. Fitzpatrick noted that birds used to living in areas with little temperature change might be especially at risk because of climate change. He said, "We should expect that what's happening on this mountain top is happening more generally in the Andes, and other tropical mountain ranges."
