1 . The newly-elected president of Brazil, Jair Bolsonaro says that his country should withdraw (退出) from the 2015 Paris Agreement, and that Brazil’s rainforest protections are standing in the way of economic success. During the election campaign, he promised to ease protections for areas of the Brazilian Amazon set aside for native people and wildlife. Are Brazil’s rainforests in danger?
The Amazon, the world’s largest rainforest, is called “the lungs of the planet.” Each tree takes in and stores carbon dioxide from the air around it. Billions of trees pull up water through their roots and release water vapor into the air, forming tiny drops of water. The Amazon creates 30 to 50 percent of its own rainfall. Carlos Nobre, a climate scientist, says that it is almost impossible to say Just how important the rainforest is to the planet’s living systems.
Some of Bolsonaro’s support comes from business and farming groups. One supporter, Luiz Carlos, noted that farmers “are not invaders, they are producers.” He blamed the past government for supporting rainforest protections at the cost of farmers. “Brazil,” he said, “will be the biggest farming nation on Earth during Bolsonaro’s years.”
Paulo Artaxo, a professor of environmental physics at the University of Sao Paulo, says that if Bolsonaro keeps his campaign promises, then “deforestation of the Amazon will probably increase quickly — and the effects will be felt everywhere on the planet.”
Other scientists warn that if the Amazon and other tropical rainforests lose too many trees, this could affect rainfall in other areas. Without enough trees to support the rainfall, the longer and bigger dry season could turn more than half of the rainforest into a tropical grassland.

2 . Paper is one of our oldest, simplest and most important inventions. But it also presents a danger to the world in two significant ways. First, the making of paper requires the loss of millions of trees each year. Between 2001 and 2019, the world lost 386 million hectares of forest. Of the trees that were cut down, 42% went to paper production. And worldwide use of paper is expected to double in the next 40 years. Clearly, the planet cannot sustain such a high rate of forest loss.
The second great problem with paper is what happens once it is no longer useful. A huge quantity of wastepaper ends up in dumps and landfills (垃圾填埋场), where it can produce harmful gases. Paper in landfills leads to the release (释放) of methane, a gas that is a significant contributor in global warming.
One simple solution can greatly reduce both of these problems: paper recycling. Paper is mainly made from cellulose (纤维素), which makes up the cell walls of trees and many other plants. Because of its structure, cellulose can be used repeatedly in papermaking. So far, trees are the only source of cellulose that can fill the massive demand for paper products. Therefore, recycling paper is simply one of the best ways to save trees.
Thanks to advances in processing, recycled paper isn’t the dull-colored stuff many of us are familiar with any more. It now can offer the same print performance as non-recycled paper.
Effective recycling requires a consistent effort. The way to begin is with education and understanding. Once enough people realize the need for recycling, more effective recycling systems can be carried out. The massive loss of trees affects everybody on earth. Everyone should do their part to recycle paper and encourage government and industries to do the same.

5 . As a result of pollution，Lake Erie, on the borders of the USA and Canada, is now without any living things.
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight. Very often the effects of pollution are not noticed for many months or years because the first organisms (生物体) to be affected are either plants or plankton(浮游生物). But these organisms are the food of fish and birds and other creatures.When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it’s not until dead fish and water birds are seen at the river’s edge or on the seashore that people realize what is happening.
Where do the substances which pollute the water come from? There are two main sources of sewage (污水) and industrial waste. As more detergent (洗涤剂) is used in the home, so more of it is finally put into our rivers, lakes and seas. Detergents harm water bird, dissolving the natural substances which keep their feathers waterproof. Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful as there are many highly poisonous things in it, such as copper and lead (铅).
So, if we want to stop this pollution，the answer is simple: sewage and industrial waste must be made clear before flowing into the water.It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.

6 . Keeping curious kids from disrupting wildlife
Interacting with the wild, naturally curious kids tend to collect seashells at the beach or keep small wildlife as pets.
Take an interest, not things. Kids show interest in picking flowers, rocks, or shells outdoors. They’re part of wildlife's habitat and play an important role.
Admire animal afar, not disrupt nearby. The urge to take a photo with a squirrel, bird, or slow-moving turtle can be strong for kids.
Take well-worn paths, not off-road romps (嬉戏). Kicking piles of leaves, stepping on bushes, and walking through forested areas can unintentionally scare wildlife. If surprised animals defend their homes, everyone could get hurt. Nobody likes having a guest come in and destroy their home and act rudely.
| A．Keep snacks away from animals. |
| B．Share food if animals are hungry. |
| C．Exposure to them develops kids’ love and curiosity. |
| D．The same rule applies to visiting wildlife in their homes. |
| E．Animals rely on plants for hiding; rocks and shells, for homes. |
| F．Approaching animals disrupts what they do for survival, such as eating. |
| G．Despite innocent purposes, kids’ curiosity accidentally damages the wild. |

8 . A team of scientists has come up with a plan to help rebuild the Arctic (北极) ice cap.
Usually, the sea ice gets thicker and spreads further each winter, but this hasn't happened for the past few years.
Last month, the ice cap had reached its smallest size since scientists began keeping a record of it 38 years ago. The weather in the Arctic has been unusually warm this winter. Some days, temperatures have been 20 degrees Celsius higher than before at this time of year. With less ice, the Arctic would warm up even more quickly, and more ice would melt (融化). Without sea ice, many animals would lose their natural homes.
Dr Steven Desch and a group of scientists from Arizona State University in the United States think they can help to build up Arctic sea ice again. They want to fix wind-powered pumps (抽水机) on the sea ice. During the winter, the pumps would spread water from the ocean over the surface of the ice where it would freeze and form a new layer of ice. The scientists say that in 10 years, this could add a metre of ice to the ice cap.(The Arctic ice cap is about two to three metres thick right now.)
The plan would require about 10 million pumps and it would be very expensive—about $655 billion. Some other scientists are wondering if the pumps would actually work in cold Arctic conditions. They are also worried about how the project might affect the environment.
Dr Desch and his team hoped their plan would get more people interested in looking for a solution to the problem of melting sea ice. He said the only plan people have right now is to try to cut greenhouse gas emissions (温室气体排放) from cars and other man-made sources. He and his team don't think that will be enough to save the sea ice, but hope it will get everyone moving in the right direction.

10 . 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 Speedo !
Pugh is an advocate for our oceans and seas, working to protect these ecosystems with their large diversity of marine life. When asked why he doesn't wear a wetsuit(防寒泳衣), Pugh 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 degrees Celsius. 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 Pugh 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.
