2 . The sunflower sea star has been listed as a critically endangered species following a groundbreaking population study led by Oregon State University (OSU) and The Nature Conservancy.
“These giant sea stars used to be easy to find and were a hit with divers. Unfortunately, your chances of finding one now are next to nothing in most of the areas near the United States—this listing is one step to extinction—and I don’t think they’re coming back without help,” said OSU’s Sarah Gravem, a research associate in the College of Science and the lead author of the study.
Populations of the sunflower sea star suffered dramatic crashes because of a marine (海洋的) wildlife epidemic event, which began in 2013. Scientists used more than 61,000 population surveys from 31 data sets to calculate a 90.6% decline in the sunflower sea stars and estimated that as many as 5.75 billion animals died from the disease, whose cause has not been determined. Moreover, the research showed no sign of population recovery in any region in the five to seven years since the event.
Sunflower sea stars are a key catcher of purple sea urchins (海胆) and the sea star decline has helped the increase in the urchin population in many regions. Too many urchins are linked to a decline in kelp forests（海藻林) already facing pressure from marine heat wave events, making the future uncertain for ecosystems that provide habitat for thousands of marine animals and help support coastal economies.
“Because most people are not out in the ocean every day, we don’t realize how much it’s being changed and impacted by humans. We need to think about how to keep our ocean healthy. While reducing the release of carbon dioxide is the most pressing need, rebuilding key catcher populations, like the sunflower sea star, can be an important piece of the puzzle too,” said study co-author Sara Hamilton, a Ph. D. candidate in the OSU College of Science.

3 . On November 7, Lewis Pugh completed a one-kilometer swim in the freezing waters of King Edward Cove, off South Georgia in Antarctica. He was wearing only his swimming glasses, cap and Speedos!
Pugh is an advocate for our oceans and seas, working to protect these ecosystems with their large diversity of marine (海洋的) life. When asked why he doesn’t wear a wetsuit (防寒泳衣), Lewis says, “I ask world leaders to do everything they can to protect our oceans. Sometimes the steps they need to take are difficult and unpopular. If I’m asking them to be courageous, I must also be. Swimming in a wetsuit would not send the right message.”
It took Pugh about 19 minutes to complete the one-kilometer swim in Antarctica where the water averaged about 1. 6℃. He says that his body can only tolerate about 20 minutes in the freezing waters before it starts shutting down. As he swims, his body temperature steadily drops, which in turn causes his muscle control to drop, slowing him down. When he is done with his swim, his support team rushes him to a hot shower and it takes almost an hour for his body temperature to return to normal.
Doctors and Pugh caution that one must receive months of training to swim in such cold waters. Even expert swimmers who are unused to freezing water can drown within minutes because of the physical shock experienced by the body. Pugh says he trained for six months before this swim.
This is not the first time that Lewis has swum in dangerous conditions. In 2007, he swam one kilometer in the North Pole to draw attention to the melting Arctic ice due to climate change. In 2015, he swam in the Bay of Whales in Antarctica’s Ross Sea as part of his successful campaign to help set up a marine reserve there.

4 . 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.

5 . Tips for Green Travel with Kids
Travelling doesn’t mean letting go of all the eco-friendly choices we work so hard to achieve in our daily life. Here are a few tips for green travel with kids.
Booking nonstop flights whenever possible will reduce carbon emissions (碳排放). If the closest local airport doesn’t have nonstop flights to a certain place, check with other local airports to see if nonstop flights are available.
It’s easy when travelling to pull in to fast food restaurants for snacks.
| A．Walking is good for your health. |
| B．Try to cut back to save water and energy. |
| C．But you can pack healthy food from home. |
| D．Travelling is a great chance to introduce your kids to the world. |
| E．Reusable water bottles are easy to bring along wherever you travel. |
| F．Save energy by turning off the hotel room lights when you head out for the day. |
| G．You might have to drive a bit farther, but saving on carbon emissions makes it worthwhile. |
6 . Las Vegas city in Nevada is built in a desert. The city may be known to the outside world for its partying. But officials have found that there are 21 square kilometers of useless grass. The grass is never laid on, played on or even stepped on. The grass is only there to look nice.
Now, the city is asking the Nevada state legislature (立法机构) to ban useless grass. It is trying to become the first place in America to ban that kind of grass often seen between streets, in housing developments and in office parks.
It is estimated (估计) that useless grass makes up 40% of all the grass in Las Vegas and it needs a lot of water to survive. Grass needs four times more water than dry climate plants like cactus. By tearing out the grass, the city could reduce yearly water usage by 15%.
In 2003, the Southern Nevada Water Authority banned developers from planting grass in front of new homes. It also offered homeowners $30 for each square meter of grass they tear out. But fewer people are now using the program. Water usage has increased in southern Nevada by 9% since 2019. And last year, Las Vegas set a record of 240 days without major rainfall. The Colorado River provides much of Nevada’s drinking water. The river could lose more water as climate change affects it.
Water officials (官员) in other dry cities said water usage needs to be reduced. But they fear the reaction to reforms like the ones in Las Vegas if their communities do not accept them. Cynthia Campbell is the water resources adviser for the city of Phoenix in Arizona. “There might come a point whencity restrictions(限制) get too severe (苛刻的) for some residents (居民). They’ll say that is the point of no return for them,” Campbell said. “For some people, it’s a pool. For some people, it’s grass.”
1. Why does Las Vegas city try to ban useless grass?| A．To protect the local people. | B．To beautify the city. |

7 . All living things on Earth need water to live. Yet humans are facing serious water problems. According to the United Nations, today over 663 million people live without a safe water supply close to home.
To remind people of the importance of water, the UN first set up World Water Day in 1993. It is on Mar 22 each year. From Mar 22 to 28 is also the China Water Week. The first year’s theme is “Waste water”. It tried to call people to reuse waste water instead of wasting it.
In Australia people make good use of waste water. Most Australians have a grass lawn around their home instead of washing the car in the street. Many of them wash it on the lawn to keep the grass longer so that it covers the ground and reduce evaporation.
Rainwater may seem useless to you. But you can also reuse it. People in Germany collect rainwater to wash their toilets. Most houses in the country that are built in the last few years have rainwater collection devices (设备). Rainwater is collected from the root, and then linked to the toilet. But if you don’t have the device just put a bucket (桶) under your roof when it rains.
Water makes up 71 percent of Earth’s surface. But we can only use a very small part of it. Only about 3 percent of the world’s water is fresh water. It’s in lakes, rivers and underground.
Over 80 percent of the w
aste water in the world goes back into the nature. It has not been cleaned and pollutes the rivers and lakes. Unsafe water makes around 842,000 people die each year.
By 2030, about half of the world’s population could be facing water problem. By 2050, as many as seven billion people across the world could not have enough water supplies. The world’s population might be 9.3 billion by then.

9 . China is showing the world its great resolve in the global climate campaign with concrete and selfmotivated efforts as well as serious commitment.
At the opening ceremony of the Paris climate summit, Chinese President Xi Jinping restated China’s plan made in June to cut its carbon emissions( 排放)per unit of GDP by 6065 percent from 2005 levels by 2030, and increase nonfossil fuel sources in primary energy consumption to about 20 percent.
With a large population, China is facing increasing resource limits, severe environmental pollution and a worsening ecosystem, and its citizens are also becoming increasingly aware of environmental problems. Suffering environmental problems and seeing the efforts as important to transforming its economic growth pattern, the country has much at risk if climate change is left unattended.
Actually, climate change efforts are already included in China’s mediumand longterm program of economic and social development, and ecological efforts are the clear characteristics in China’s 13th FiveYear Plan(20162020)．
Although it is and will be a developing country for a long time to come, China has been actively involved in the global campaign against climate change, now topping the world in terms of energy conservation and use of new and renewable energies.
However, China’s development rights need to be respected. It is unfair to overstress China’s status as one of the world’s largest greenhouse gas emitters and regard it as the major part of responsibilities in the global fight against climate change.
It is worthy of notice that China’s emissions of greenhouse gases per person are far lower than those of developed countries, especially the United States, although rapid economic expansion and its population base have made it one of the biggest producers of the gases.
To show its great resolve, Beijing in September also announced the establishment of an independent SouthSouth cooperation fund of ￥20 billion to help developing countries affected by global warming.
While China is eagerly accomplishing its policy commitments, developed countries should stop questioning China’s commitment to fighting climate change and pointing fingers, and start shouldering their due responsibilities instead.
