1970 was World Conservation (保护) Year. The United Nations wanted everyone to know that the world is in dan?ger. They hoped that govemment(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(毁坏 )by modern man and his technolo?gy (技术). We are changing the earth, the air, water and eve?rything 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 im?portant to ask： "What, must we do now?"The people who will be living in the world of tomorrow are the young of to?day. 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 Li?nited States, a large number of girls cleaned the banks of 11 kilometres of their river. Young people may hear about con?servation 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 ani?mals.
