1 . There’s been a lot of talking about white-and-blue collar workers, and you may have even heard of gold collar workers, but lately a new color of collar is making its way into China’s urban vernacular(土话)—green. Green collars say no when work is life and life is work. They choose to get out of the fast lane(车道), and explore new ways of living “green”.
Living green doesn’t mean someone is working as an environmentalist, biologist or scientist. Instead it is more of a lifestyle choice. A typical green collar is well educated like a white-collar but physically tough like a blue-collar, likely born in the 70s or 80s of the last century and living in one of China’s big cities, with a monthly income well above 5,000 yuan(about US $700).
The life of a green collar may go something like this: Turn off the mobile phone after work, eat only healthy food rich in vitamins, go on hikes every weekend, and like to help the underprivileged.
Green collars even have their own club. In Beijing, the Green Collar Club is for people who share a “be happy, healthy and helpful” spirit. The club often holds charity parties and uses the donations for environmental protection and poverty relief(摆脱贫困) projects in China.
“They are successful in their careers, but do not miss the pleasures in life. They have a lot of money, but do not fall slave to it.” said Zuo Shiguang, one of the founding members of the club.

2 . Yosemite is a national park in California. It is very beautiful and big. The park includes more than 760,000 acres in the California Mountains. Most of the park is wilderness.
The part of Yosemite that everyone likes is Yosemite Valley. It is a tiny valley that is 7 miles long and less than 1 mile wide. It has tall rock walls and streams that splash down in waterfalls. More than two million visitors come to the valley each year.
One ranger (守护人) says the number of visitors is more than the land can handle. The valley has 4,500 camping spots. It has a hotel that can hold 4, 000 families. This is still not enough to handle all of the visitors. The valley has grown so big that it has a lot of traffic and crime.
A worker says the park is trying to keep the beauty of the park and let everyone visit. Some areas have been fenced off from people and planted with seeds to try to keep them beautiful.
A former worker thinks Yosemite should get more money to take better care of the park. He would also like to teach people what the park service is trying to do.
Some people are trying to save Yosemite Valley. A plan has been made to get rid of some buildings. There will be fewer cars allowed inside the park. More buses will help get people around.

3 . It is the year 3000. I come to a place where I can’t see any water, plants or animals but black clouds in the sky and sand everywhere. It’s very dry so I drink some water that I carry with me. A native sees what I do and asks “What is it?” I pour some water and tell him it’s called water. “Oh, I’m so lucky that I can see water!” the man shouts in an excited voice. “You have never seen water? But how can you live without water?” I ask.
“Harry, get up, it is 7 o'clock, or you will be late!” a voice comes to my ears. “Oh! What a strange dream I dreamed just now!”
In class, I always think of that dream. And I also think of the fresh air, clean water, blue sky, green plants and animals in our world nowadays. How beautiful our life is!
But in order to make more money, people have built more and more factories. These factories send out waste smoke and water with chemicals which are harmful to the environment. The pollution is becoming worse and worse, and as a result, some animals and plants die out. With the development of agriculture, farmers spray aerosol (喷雾) and fertilizer, which also pollute the water and air. In the street the cars and buses are sending out heavy smoke which pollutes the air badly. Even tourism is harmful to the environment. When some tourists travel somewhere, they throw the plastic bags and rubbish onto the ground.
These behaviors are polluting the environment and the environment will become the greatest problem of the world. We shouldn’t pollute the environment any more. Otherwise more and more animals and plants will disappear. And maybe my dream will come true in the future.

4 . 83-year-old Antonio Vicente has spent the last four decades of his life fighting against the current. As Brazilian landowners cut down rainforests to make room for profitable (盈利的) plantations and cattle grazing grounds, he struggled to bring the thick jungles of his childhood back to life.
In 1973 Antonio took up the challenge of restoring the forest on a 31-hectare piece of land that had been destroyed for cattle grazing. Ironically enough, he bought the land in Brazil's Sao Paulo region, using credits （贷款）that the military government was giving out to promote deforestation (砍伐森林) and agricultural technology. But Antonio didn't use the money to promote the national agriculture but wanted to revive the forest.
"You are stupid. Planting trees is a waste of land. You won't have income. If it’s full of trees, you won't have room for cows or crops," Antonio's neighbors told him. But he knew the damage caused by deforestation was far greater than financial profit. Antonio had grown up on a rural farm, and watched his father and the other villagers cut down forests at the owners’ orders, either for charcoal production or to clear land for grazing cattle. He had watched the ancient water sources dry up and people struggling to survive.
With only some donkeys and a few hired workers Antonio brought back the forest to his land. What started out as a weekend hobby soon became a permanent way of life. Antonio often recalls spending days and nights in his young jungle, surrounded by rats and foxes, and eating banana for breakfast, lunch and dinner.
As the forest grew, the water returned, and Antonio says that there are now over 20 water sources on his land that were no longer there when he bought it. Then the animals started making a home there. Today, the forest is alive with sounds of birds and insects living there, and more species are settling in every year.

The report has been produced by the US Geological Survey. The scientists have publicized their findings in the hope of influencing US Interior Secretary Dirk Kempthorne，who has been asked to put polar bears on the US endangered species list.
Polar bears depend on floating sea ice as a platform for hunting seals，which are their main food. Without enough ice，polar bears would be forced to go onto the land，where they are poorly skilled hunters，and would be unlikely to adapt to the life on the land in time. Experts say few little bears would survive and the stress could make many females unable to get pregnant.
The team of American and Canadian scientists spent six months studying bears，on the ground，from spotter planes and in the lab，using computer models.
Some team members fear the result is even worse for the bears than what their report says. They say the Arctic is warming faster than anywhere in the world and much faster than their computer had been forecasting. Satellite observations have showed that the ice has decreased to an all－time low.
However，not everyone in the scientific community believes that global warming is happening on such an alarming scale. Another investigation has found that polar bears are still being hunted by wealthy “sportsmen” who want their skins and heads. At least ten international companies offer bear－hunting trips.

6 . As the population of the planet increases, so does the number of homes, business, parking lots, schools, airports and roadways. All these structures use electricity and need to be lighted. Humans demand light. They want their homes more comfortable and they want their streets safe. The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well.
Less than 10 years ago I drove to a thinly populated section of my own, lay down in the middle of the road and watched an attractive meteor shower(流星雨). If I did that today, I wouldn’t be able to see the meteor shower.
Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide （二氧化碳）pollution. One of the saddest parts of light pollution is that most of it is unnecessary and most of the outdoor light that we use is wasted. One only needs to look at a row of street lights to see how much of the lights shines upwards and lights the sky: a total waste of electricity.
Additionally, the production of electricity cr
eates pollution by releasing greenhouse gases. This affects the air we breathe and our quality of life.
Scientists are also studying the effects of light pollution on wildlife. Thousands of birds die each year when they crash into highly lighted buildings, as they become puzzled by the light. It has been long known that tiny baby sea turtles become lost and follow the light on the shore instead of heading towards the sea.
Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution.
