1 . 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.

2 . Jane Goodall, the well-known scientist, is starting Trees for Jane on Tuesday, joining a global campaign to fight climate change by planting a trillion trees by 2030.
Goodall made it clear that planting is just one part of Trees for Jane. “The key is protecting existing forest because those big trees have already stored CO2,” she said in a National Geographic interview. Donations to Trees for Jane will support local groups working to stop destroying trees. And those who plant are asked to agree to care for the trees and monitor them until they’re mature(成熟的).
Of course, tree planting is not a substitute for reducing emissions (排放), said Susan Cook-Patton, senior forest restoration scientist for The Nature Conservancy. “The most important action is to reduce fossil fuel emissions. However, even if we rapidly reduce emissions, we’re still going to need to remove carbon from the atmosphere to prevent catastrophic warming. That’s why carbon removal approaches like re-growing trees remain important.”
Some tree-planting efforts have come under fire from some scientists as being ineffective since many programs don’t plant native species, essentially creating tree farms, not helping forests. And Cook-Patton’s message is clear, “Plant the right trees, in the right places, in the right way.” This means planting native trees where they historically lived.
Goodall said this agrees with the goal of Trees for Jane. She, noting that Trees for Jane encourages people to plant trees themselves or donate to support global efforts, said her love for trees dates back to her childhood. Nearly eight decades later, she is working tirelessly and selflessly to share the gift of trees with the entire world, for the good of the planet.

3 . There are many wetlands（湿地） in China and some of them have become the world’s important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng，Jiangsu Province. They are home for many different kinds of birds and animals. The world’s largest Milu Deer Nature Reserve（自然保护区) is in them. More than 700 milu deer live freely there. There are not many red-crowned cranes in the world, but every winter you can see some in the Red-crowned Cranes Nature Reserve in the Yellow Sea Wetlands.
The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine，too. They are really good places for wildlife（野生生物）. Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.
Luckily, more and more people are beginning to realize the important of wetlands and wildlife. Every year，on February 2nd，many activities are held to tell people more about wetlands.

4 . If you turn over a plastic bottle, like those we use to drink water, you’ll notice a number “1”—that means it’s made of a material called PET. Some bags, like the kind that holds milk or coffee, get a “2”，meaning they’re made of a material called HDPE. At material recovery factories, plastics get sorted (分类) based on these numbers (they go up to 7)，which shows how recyclable (可回收的) they are.
Plastic marking numbers 1 and 2 are recyclable. They can be made into carpet, clothing, plastic package, as well as other products, according to Live Science.
Recycling gets more difficult with higher numbers, called “mixed plastic”. This waste makes up 69% of all the plastic we use in the daily life. It’s much more expensive to deal with than numbers 1 and 2. In the past, mixed plastics would be sent to other countries. But two years ago, almost no country was allowed to buy foreign plastic waste.
Recycling companies had to find a new market, but many failed. For example, in Los Angeles, recycling companies still won’t recycle any plastics with numbers higher than 2. Instead, they are burying or burning them.
According to Live Science, what the USA needs is machines that can be used to recycle other kinds of plastic. But Hocevar, a scientist, comes up with a different solution: “The really simple answer is there isn’t so much throwaway plastic in the world.”
Someone may ask, “Is recycling worth it?” For bottles with “1” or “2”, the answer is “yes”, said Hocevar. There’s also a growing market for plastics marked “5”, a flexible (灵活的) plastic that includes yogurt containers (酸奶容器). For other numbers, the answer was simpler; a “no” on numbers 3, 4, 6 and 7.

Thanks for your concern in your letter about the smog which frequent strikes some areas of China. I’m also very worrying about such a terrible weather. It has brought much inconvenience or rather harm to people's health such as road accident, bad coughs and even lung cancers and so on.
It is known to all, good environment comes from careful protection. But we should do what we can protect it. I believe a small step can make a different. Try to drive less and choose air-friendly products. Only when everyone had the environmental awareness can we have a blue sky. Hope to hear from you and share my good ideas.
7 . In the past hundred years, a million people have died in earthquakes, another million have been killed by hurricanes and tornadoes, and 9 million have lost their lives in floods. In addition to this, many millions have died as a result of hunger and disease. We should also not forget in many of the world's countries, drought—serious water shortage—is a fact of life, especially in the African Sahel area bordering the Sahara Desert.
Scientists and engineers around the world have made great advances in earthquake engineering. It is, of course, physically impossible to move cities such as Tokyo and San Francisco that have been built on earthquake belts. But most often it is not the earthquake that kills people. It is the falling buildings, bridges and so on that cause deaths, and such a happening can be greatly reduced by better building programs.
Finally, perhaps we need to consider the natural disasters that we are causing ourselves. Through our mismanagement of the planet's resources we have sped up the dying out of hundreds of sorts of plants and animals, at the same time possibly destroying our own long-term surroundings for life. Maybe this is one disaster that could be prevented if we are willing to act with a sense of responsibility.

9 . The Sanjiangyuan National Park, China's first experimental national park, has been established to protect the local environment. The area is known as the country's "water tower" because it houses the headwaters of the three great rivers of the country: the Yangtze, the Yellow and the Lancang rivers.
Covering a total area of 123,100 square kilometers, the national park emphasizes the protection of the entire ecosystem, including all of the local natural resources such as wild animals, water, grassland and forests.
Since the national park started its trial operation in 2016, locals have been called on to help protect and improve the environment. Their work includes patrolling (巡逻) the grassland as well as monitoring and rescuing the park's wildlife. To date, there are 17,211 rangers (护林人) operating in the national park.
Kunsang, now 39 years old, is a Tibetan herdsman (牧人) turned park ranger for the headwaters of the Yellow River in the national park. On November 16th, 2020, Kunsang put his life at risk while attempting to save a wolf trapped in a broken ice patch on a lake. Braving temperatures of minus 10 degrees Celsius, Kunsang rushed over to the wolf and pulled the wild animal out from the icy opening on the frozen lake with the help of his colleague.
The efforts of rangers including Kunsang are paying off, and the national park has seen its wild animal populations bounce back apparently in recent years. Hoh Xil (Kekexili) National Nature Reserve, one of the largest no man's lands in China and a part of the Sanjiangyuan National Park, is now home to more than 70,000 Tibetan antelopes, said Wang Xiangguo, deputy director of the park. The official explained that the population numbers for the rare species, which is under first-class state protection in the country, once declined sharply to no fewer than 20,000 due to the impacts of illegal hunting.
