1970 was World Conservation(自然保护)Year. The United Nations wanted everyone to know
that the world is in danger. They hoped that people would act quickly in order to conserve nature(大
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.
It is said that there are tens of thousands of kinds of animals in the world, but now many have died
out(绝种). We are changing the earth, the air and water, and everything that grows and lives. We
can"t live without these things. If we continue 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 that
conservation is necessary. Many are helping to save our world. They plant trees, build bridges across
rivers and so on. In a small town in the United States a large group of girls cleaned the banks of 11
kilometres of their 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.
