　　1970 was the “ Would Conservation 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(保护)nature．Here is one example of the problem．At one time there was 1300 different kinds of plants, trees and flowers in Holand , but now only 866 remain．The others have been destroyed by modern man and his technology．We are changing the earth．the air and the water, and everything that grows and lives here．We can’t live without these things．If things 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 ing 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 kilometes 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 and other singers．The money from it will help to conserve animals．
