     1970 was the 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 in order to conserve nature. Here

is one example of the problems. At one time there were 1 300 different plants, trees and flowers in Holland,

but now only 860 remain (留下). The others have been destroyed (毁灭) by modern man and his technology

(技术). We are changing the earth, the air, the water, and everything that grows and lives. We can't live

without these things. If we go on 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 people today. A lot of them know that conservation

is necessary. Many are helping save our world. They plant trees, protect wild animals, and so on. In a small

town in the United States a large group of girls cleaned the 11 kilometer-long banks of the river. Young people

may hear about conservation 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.
