2 . Kevin Randall, a teacher,who teaches biology at Grandville High School,runs the environmental club at the high school,which has around 2,000 students.The club is known as the GHS Green Team,and it aims to raise awareness among students and teachers about sustainability(持续性).It also works on projects to reduce the environmental footprint of the building itself.
One of the club's recent projects focused on reducing waste in the school cafeteria.Randall said their cafeteria supervisor told them that the school went through 54,000 plastic forks every year.The club applied for a financial help,built recycling centers for the cafeteria,and purchased metal silverware.
And now every student uses a durable metal fork or a spoon instead of disposables.(一次性用品),“and that's just one way we're trying to capture the low-hanging fruit,if you will,"Randall said.
The efforts of Randall and his students have earned Grandville High School the Michigan Green School certification from the state.In addition to their work reducing waste in the cafeteria, the GHS Green Team has also built a garden with flowers and vegetables on campus,and leads cleanups on site and out in the community.Over the years,Randall and his students have also been working on raising money to install solar panels(太阳能板) on the roof of the high school.
Randall said he was motivated to take the lead on environmental issues for his school because he wanted his students to have someone to turn to in the building who understands what's at stake(利害攸关）when it comes to climate change.
＂And I also felt like I needed to do more in my life for my own two children at home," Randall added,"They need to know that their dad is working as hard as he can to reduce the effects of climate change,and to spread the word,and to make sure that other students out there are learning about this just the way they are at home."

5 . China is known for its long history, rich culture, and cute pandas. It’s also known for some of the worst air quality in the world. But the Asian country is now using a natural weapon against air pollution — trees.
In February, China’s government announced plans to cover at least 32,400 square miles with forest. That is about the size of Ireland. Some 60,000 soldiers will take charge of the tree-planting program. Most of the trees will be planted in Hebei Province. That is an area surrounding China’s capital, Beijing.
Huang Wei is an environmentalist who works for Greenpeace East Asia. She is optimistic about the plan. “Trees act as a sink to absorb carbon dioxide and other pollutants,” she said. Carbon dioxide is a gas that traps the Earth’s heat. It contributes to global warming.
Why is China’s air filled with harmful chemicals? It’s because the country relies on coal-fired power plants. When coal is burned, PM2.5 is produced. PM2.5 is a pollutant. It can cause shortness of breath, heart attacks, and even death.
Just two years ago, pollution levels were so high in Beijing that schools and factories had to close. Huang hopes China’s tree-planting plan will reduce the nation’s suffering from air pollution.
The Chinese government is getting help from others in its drive to make the nation greener. Stefano Boeri is an Italian architect and urban planner. He is leading an effort to plant vertical (垂直的) forests in China.
Boeri’s designs have already taken root in the city of Nanjing, China. That’s where the Nan-jing Green Towers are under construction. The building has two towers. Thousands of trees and hanging plants will grow on the balconies and rooftops.
Boeri says his goal is to design buildings that help the environment and improve air quality. He also hopes to encourage a new generation of green architects.

6 . Just a year ago, the colors were bright under the waves. Now it’s gray — the Maldivian reef is dead. The coral is killed by the pressure of rising temperatures.
Coral reefs are areas underwater where small creatures live. The coral is hard material formed on the bottom of the sea by the skeletons of those creatures. But the world has lost about half its coral reefs in the last 30 years. Scientists are working to prevent their destruction. Due to global warming, over 90 percent of corals are expected to die by 2050. “To lose coral reefs is to fundamentally undermine the health of a very large proportion of the human race,” said Ruth Gates, director of the Hawaii Institute of Marine Biology.
Why are coral reefs important? Coral reefs support a fourth of all marine species, as well as half a billion people worldwide. They serve as barriers to protect coastlines from the storms. They provide billions of dollars from tourism, fishing and other trade. They are also used in medical research for cures for diseases. “Everyone should be concerned,” said biologist Ove Guldberg at Australia’s University of Queensland. “This is not just some distant dive destination. This is the basic structure of the ecosystem we depend on.”
The ocean is getting warmer. A rising temperature of just one to two degree Celsius can force coral to expel the algae (驱逐海藻) that live there. This leaves their white skeletons uncovered. It is a process called “bleaching”. Sixteen percent of the world’s corals died of bleaching in 1998. The problem has become much worse in recent years.
“We’ve lost 50 percent of the reefs, but that means we still have 50 percent left,” said Ruth Gates, who is working in Hawaii to breed corals that can better withstand increasing temperatures. She is also trying to “train” corals to survive rising temperatures. Gates says it is time to start “thinking outside the box”— find creative ways to help them.

7 . ''It can't be done. '' Boyan Slat heard this over and over when he first proposed a way to clean up millions of tons of plastic polluting our oceans.
Slat, who grew up in the city of Delft in the Netherlands, was on a diving trip in Greece three years ago when he was deeply impressed by plastic. ''There were more plastic bags than fish, '' he says. ''That moment I realized it was a huge issue and that environmental issues are really the biggest problems my generation will face. ''
That fall, Slat, then 17, decided to study plastic pollution as part of a high school project. Soon, Slat learned that no one had yet come up with practical way to clean up this massive garbage patches. Most proposed solutions involved ''fishing'' up the plastic using ships equipped with nets—which, as Slat discovered, would likely take more than 1,000 years, cost too much, let off too much sea life along with the trash.
Slat proposed an alternative that mostly avoided these problems: a solar-powered system using a floating plastic tube which will go around the garbage and trap it is 600 meters long. Wind, waves and ocean currents will push the trash toward the tube. A ship will pick up the trash and take it back to the shore. Best of all, Slat predicted his system could clean up the North Pacific Garbage Patch within five to 10 years.
The following, Slat entered the aerospace engineering program at the Delft University of Technology and officially announced his ocean cleanup concept at TEDxDelft. But nothing much moved forward.
Slat organized a team of volunteers and employees for The Ocean Cleanup, which now numbers about 100. In answer to opposition, Slat and his team raised $100,000 from a crowd funding campaign and began testing a 40-meter collecting barrier near the Azores Islands last March.
Over the next three to four years, Slat will push toward a fully operational large-scale project by testing a series of longer and longer barriers.

8 . E-waste is fast becoming a serious global problem.
The source of e-waste
We live in a society that constantly produces and consumes electronic products. It is often cheaper to buy new pieces of equipment than to repair old ones. Also, through clever advertising, companies persuade consumers to replace their old TVs, mobile phones and computers for the latest models. E-waste is created when we throw away electronic equipment like this. In the EU alone, about 8.7 million tonnes of e-waste is produced each year.
The problem with e-waste
Burying e-waste in landfills or burning it causes serious problems for the environment.
Global recycling schemes (计划)
Take-back policy
Another solution to e-waste is to make manufacturers responsible for their used products. This could mean forcing them to take back old products which are no longer wanted.
Consuming less
We can all reduce the amount of waste we produce by buying electrical products only when we have to.
| A．In recent years, many countries have started recycling e-waste. |
| B．They should then make sure they are properly recycled or reused. |
| C．Sadly, just over one million tonnes is recycled. |
| D．This report will examine this problem and provide some possible solutions. |
| E．By resisting the temptation to buy a product just to have the latest version, we cut down on e-waste. |
| F．Electronics contain dangerous chemicals and metals. |
| G．Both manufacturers and consumers must accept their responsibilities and make efforts to keep it to a minimum. |
9 . The early life of the green sea turtle (海龟) is full of danger. Only one in 1,000 baby sea turtles survive to adulthood (成年). From its home in the sand, it breaks its egg with an egg tooth. Its mother is not there to help it. Instead, it is greeted by crabs, coyotes, and dogs waiting to eat it for dinner. To survive, the baby turtle must hide in the sand until night. Then, it moves slowly to the sea.
The small turtle must swim hard to reach the ocean waters. In the sea, it tries hard to find food. It must also keep itself from being food for fish.
As dangerous as the sea turtle’s life is in the natural world, its most dangerous enemies are humans. The rubbish left by humans in the ocean causes problems for the small green sea turtle. A little turtle might eat a piece of plastic (塑料) in the sea. It might also eat oil on the ocean’s surface. Young turtles also get caught in fishing nets. There are laws against hunting sea turtles. Still, many are hunted, both for their meat and for their shells (壳). All of these dangers must be prevented.
Sea turtles that do survive to grow into adulthood go through many changes. For example, adult green sea turtles weigh about 500 pounds. They stop eating jellyfish and other meat and eat only plants. And they may plan a trip to go back home again. A mother sea turtle goes back to the beach where she was born. This is the only place where she will lay eggs. Even if it has been forty years since she was a baby, she always knows her way back home.

10 . The Great Wall, China
Stretching over 21,000 kilometers, the Great Wall was built to prevent invasions and has a history of more than 2,000 years. UNESCO in February 2019 calls it an absolute masterpiece, not only because of the ambitious character of the undertaking but also the perfection of its construction.”
But perfection isn’t protection. 51.2 percent of the Great Wall had either already disappeared or is at a significant risk of disappearing. Besides for wind and rain erosion, the main reasons for the destruction of the Great Wall are human factors such as tourism, construction, human contact and so on.
Pamukkale，Turkey
Pamukkale, which means “cotton castle” in Turkish, is famous for its shining white calcite terraces (方解石阶地)with warm and mineral-rich waters overrun.
Before being listed as a World Heritage Site in 1988, Pamukkale had been severely damaged by human activities. People used hot spring water to fill swimming pools, some visitors stood on the rocks and some even bathed in the hot springs with soap and shampoo. To protect the terraces, the Turkish government has decided to pull down the hotels and require all tourists to visit this site barefoot.
Great Barrier Reef, Australia
Home to 400 types of coral and 1,500 species of fish, the Great Barrier Reef draws visitors to Australia from all over the world.
However, the Great Barrier Reef is expected to suffer from increasingly frequent bleaching events, cases in which corals turn white and may die, according to a UNESCO report. The heat waves caused by global warming have killed half of the coral here in the two years, according to a CNN report. Pollution from industry developments and harmful fishing practices are also big concerns.
The Dead Sea, Jordan
At 423 meters below sea level, the Dead Sea is 10 times saltier than the ocean, meaning that the water is so dense, even tourists who can9t swim will be able to float.
But the seaside resorts built in the 1980s now sit kilometers away from the water’s edge, which has lost half of its surface area in the past 40 years. The damage is irreversible due to the nature of the mineral industry and the type of agricultural use that has drained the water.
