1 . The endangered pandas in the Qinling Mountains might face a new threat: the loss of their food, bamboo, which makes up 99% of their meals.
Adult pandas spend most part of the day eating bamboo and have to take in at least 40 pounds a day to stay healthy. However, a new study published in Nature Climate Change warned that they may soon find their food gone because most of the bamboo in the Qinling Mountains might disappear by the end of the century as a result of rising temperature worldwide.
A team made up of researchers from Michigan State University and the Chinese Academy of Sciences has studied the effects of climate change on the bamboo in the Qinling Mountains. They have found that bamboo is very sensitive to climate changes. “80% to 100% of the bamboo would be gone if the average temperature rises 3.5 degrees worldwide by the end of the century,” said Liu Jianguo, one of the report’s authors.
He added, “This is how much the temperature would rise by 2100 even if all countries will keep their promises in the Paris Agreement. But you know what is happening all around the world.”
In recent years, China has been trying its best to protect the endangered pandas by setting up more and bigger natural reserves.
“But it is far from enough and the endangered pandas need cooperation from the rest of the world, because their future is not just in the hands of the Chinese,” said Shirley Martin from the World Wildlife Fund but not a member of the team.
The Qinling Mountains, in the southwest of China, are home to about 260 pandas. That is about 13% of China’s wild panda population. In addition, about 375 are living in research centers and zoos in China.

2 . The monarch butterfly migration(迁徙)is at risk because of climate change and other envuronmental factors.
Do you know that monarch butterflies can travel up to 50- 100 miles a day? If you know they need travel about two months, you’ll have an idea of the distance monarchs travel to get to Mexico.
Monarch butterflies are the only hind of butterflies to make a two-way migration. They travel to Mexico to escape the winter season in the northern climates. Cold, wet weather is considered deadly for monarchs, while hotter, diner summer change their homes in the north.
2020, however, saw a 26% drop from the year earlier in migration patterns reported in a report from the World Wildlife Fund and the Mexican government. With this drop, the butterflies’ population covered only 2.1 hectares in 2020, compared to 2.8 hectares a year earlier. And the Monarch Butterfly Biosphere Reserve in Michoacan. Mexico, lost trees at a higher rate than it did in 2019.
With climate change as the monarch butterflies’ biggest challenge, they are faced with many dangers, such as drought, deforestation(滥伐森林)and struggle to breed. These dangers affect the whole migration and hold back population growth. Female monarchs lay their eggs on milkweed flowers, which have been heavily affected by the wild weather from spring and summer of last year. Because of this, the development of butterfly eggs was also affected.
Since 2013, Mexico has seen a rapid drop in the number of migrants arriving to the area. The effects of climate change and deforestation have become an important sign that action needs to be taken to make sure of a healthy migration for monarchs going forward. If not, it’s their possible dying, out that wall fall unto our hands.

3 . Garbage sorting (分类) has become a hot topic around China, especially after Shanghai began carrying out a regulation (规章) on July 1.
Beijing has been expected to do the same. At present the regulation gives garbage sorting responsibilities to government departments, property management groups and other organizations. It also gives rules for companies, explaining how they’re responsible for waste collection, transportation and treatment. Citizens are free of responsibilities for the moment.
The long-awaited revision will soon change the situation. “Taking out the trash without sorting it properly will be illegal,” said Sun Xinjun, director of the Beijing Commission of Urban Management. In Shanghai, violators (违背者) are now fined up to 200 yuan for trash-sorting violations. “The maximum fine in Beijing will not be less than that,” he said.
The Beijing city government first promoted garbage sorting in 2009. Authorities have since called on citizens to sort their household waste into four types—recyclable waste, kitchen trash, dangerous waste and others , and leave it in a colored dustbin or trash can. Blue-colored dustbins are for recyclable items, green for kitchen trash, red for dangerous materials and grey for other waste.
To promote the awareness of garbage sorting and expand the base of participants, authorities have employed workers to help citizens. With intelligent devices, those who throw in recyclable waste at given places will be rewarded with bonus points, which can be used to buy daily goods. At some communities, there are no color-coded dustbins. Instead, a scheduled garbage collection service is offered to help improve the environment. In other communities, workers offer a door-to-door service to collect recyclable or kitchen waste.
Beijing Environmental Sanitation Engineering Group has been promoting new garbage sorting facilities such as recycling cabinets and smart kitchen waste trash cans since 2016, Xinhua News Agency reported.

Denim, that is used to making jeans(牛仔裤), is a kind of cloth of cotton(棉花). Denim is strongly enough, so after many wears and washes, jeans can still be in good condition. But during the process, in whom jeans are made，the environment is polluted, but workers’ health are affected because harmful chemicals. Now people are working on solution. To reduce the bad effects, some companies recommend wash jeans every each 10 wears. And, when possible, air dry them.
7 . In most parts of the world, many students help their schools make less pollution. They join “environment clubs”. In an environment club, people work together to make our environment clean.
● No-garbage lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school!
● No-car day. On the no-car day, nobody comes to school by car--not the students and not the teachers! Cars give pollution to the air, so remember:
Walk, jump, bike or run.
Use your legs! It’s lots of fun!
● Turn off the water! Did you know that some toilets can waste twenty to forty m3 of water an hour? In a year that would fill a small river! In environment clubs, students mend those broken toilets.
We love our environment. Let’s work together to make it clean.

Dear editor,
I’m Li Hua. Nowadays, the earth is becoming warmer and warm. In my opinion, global warming is harmful to the earth or us human beings. If the earth is becoming warmer, the sea level rise by several meters. What’s worse, extreme weathers such as severe storms, floods, droughts and so on will appear frequent. In addition to, diseases will spread and many species may disappear. In your daily life, we should walk, ride a bike or take a bus instead of driving a car, that will contribute to reducing the level of carbon dioxide. This is also important to recycle materials to reduce pollution. Only in this way can we prevent the earth from become warmer.
Yours,
Li Hua
9 . Raising a baby takes a lot of work, especially when that baby is a king penguin. Now, it looks like climate change will make life even harder for these birds. A new study suggests that warmer waters could make their numbers decrease.
Most king penguins live on the Crozet Archipelago, about 1, 000 miles north of Antarctica. After the penguin chicks are born in November, which is summer in the Southern Hemisphere, both parents spend 4 months collecting fish to feed their babies. When the fish move to deeper waters in March, the adults leave their chicks alone for months and swim hundreds of miles south. There, near the Antarctic ice, they spend the winter eating seafood to add to their own energy stores. In October, the parents return to their home.
Scientists from France have been studying king penguins for more than a decade. Starting in 2008, Yvon Le Maho and his partners put electronic(电子的) ID cards under the skin of hundreds of penguins. These are the same type of cards you might put in your dogs or cats so that you can track them. The cards have allowed researchers to get everything about penguins, such as how long they live, whether they return from their winter trips, and if their babies manage to survive the winter.
Ocean surface temperatures vary from year to year. To see whether water temperatures affect the penguins, Le Maho compared his data with temperature records. Previous research had shown that fewer fish and other creatures grew when the water was warmer. Le Maho suspected(怀疑) that this drop would make it harder for adult penguins to survive the hard times ahead. Indeed, his results showed that fewer adults survived during winters when the water was especially warm.
King penguins can live for up to 30 years. And for now, the population still appears healthy. But a warming trend(趋势) could spell big trouble for a bird that depends on cold and ice.

10 . The World Health Organization says that about 2. 2 billion people in the world still have trouble every day getting fresh drinking water especially in some countries in sub-Saharan Africa.
Now, the GivePower Foundation has developed what could be a solution to this problem. Since August 2018, the organization has been running a solar-powered desalination plant（太阳能海水淡化厂）in Kenya. The Solar Water Farm brings clean, drinkable water to about 35, 000 people every day.
GivePower says that its project is able to provide 20 years of access to clean water at a cost of only $ 20 per person—bringing not only huge health benefits to the people of the area, but breathing life into poor local economies（经济）.
Before setting up the plant, people in the area often had to travel for over an hour just to get clean water for themselves and their families. Most of the time, they had to bathe in dirty water, which led to countless health problems, including deadly diseases and waterborne illnesses.
The world faces an increasing danger of "water wars" because of increasing world temperatures and population growth as well as the inequitable distribution（不公平分配）of world resources. Hayes Barnard, the president of GivePower, hopes that the Solar Water Farm can help lead to a solution for the 844 million people around the world who simply have little access to clean drinking water—and especially those 300,000 children who die every year due to waterborne diseases. The organization has already given over 2,650 solar-powered energy systems to medical clinics, villages, and schools in 17 countries, and they are also now researching four additional places where they can set up new solar water farms.
