     1979 was World Conservation (自然保护) Year. The United Nations wanted everyone to know

that the world is in danger. They hoped that governments would go into action (采取行动) quickly  

in order to conserve nature. Here is one example of the problems. At one time there were l,300

different plants, trees and flowers in Holland, but now only 860 remain. The others have been

destroyed by modern man and his technology (技术). We are changing the earth, the air and the water,

and everything that grows and lives. We can't live without these plants. lf we continue like this, we will

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

that conservation is necessary. Many are helping td 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 group of girls cleaned

the banks of 11 kilometers of their river. Young people may hear about conversation' through a record

called  No one's going to change our world. It was made by the Beatles, Cliff Richard and other singers.

The money from it will help to conserve wild animals.
