1970 was World Conservation (保护) Year. The United Nations wanted everyone to know that the world
was in danger. They hoped that governments would act quickly in order to conserve nature. 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 a modern man and his technology. We were changing the
earth, the air and water, and everything that grows 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 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 rivers. 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.
