以1970 was world conservation开头的缺词填空

1970 was World Conservation(保护)Year.The United Nations wanted everyone to know that the world is in danger.They hope that the 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 modern man and their technology.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 act 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 youngof 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.
