Here is a page from a magazine named Future. Read the following information about things that may happen in ten years.

(C)

1970 was World Conservation(保护) Year. The United Nations wanted everyone to know that the world is in danger. They hoped that governments(政府) would act quickly to conserve nature(保护自然). Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland but now only 866 remain. The others have been destroyed by modern man and his technology. We are changing the earth, the air, the water and everything that grows and lives. We can’t live without these things. If things go like this, we shall destroy ourselves.

What will happen in the future? Perhaps it is more important to ask, “What must we do now?” The people who will be living in the world of tomorrow are the young of today. A lot of them know conservation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers in forests, and so on. In a small town in the United States, a large number of girls cleaned the banks of 11 kilometers of their river. Young people may hear about conservation through a record called “No one is going to change our world.” It was made by the Beatles, Cliff Richard and other singers. The money from it will help to conserve animals.

What do people do with their old, out of date but still useful computers? Most people don’t know what to do with them. Many old computers are put away in homes. Many more are simply thrown away as the rubbish.

Finally, some companies are thinking of ways to bring down the number of old computers. Sony has agreed to help recycle old Sony products(产品). Dell, Hewlett Packard and other companies now also take back some old computers.

In some countries, laws have been passed, too. Computer companies have to pay for collecting and recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay for the cost. That will encourage them to make computers that are easier and cheaper to repair and upgrade(升级).

Yet while many people are throwing away good computers, others cannot afford them at all. Hundreds of organizations are working to solve this problem. They collect and repair old computers. Some also teach others how to repair computers. The computers then go to schools, charities(慈善团体) and people who need them. Giving a used computer to one of these organizations can turn one person’s rubbish into someone else’s useful things and cut down waste, too.
