The year 1970 was World Conservation (保护)Year. Everyone must know that the world is in 51 . Here is one example of the problem. At one time there was 1300 different kinds of trees and flowers in Holland(荷兰), 52 only 866 remains(继续存在). The others have been destroyed by modern man. We are 　53 　the earth, the air and the water, and everything that grows and lives. If we go on like this, we shall destroy 　54 .

What will happen in the future? Perhaps it is more 　55 　to ask “ what must we do now?” The people 　56 　will be living in the world tomorrow are the young of today. A lot of them know that conservation is necessary. 57 　are helping to save our world. Now fifteen million young people in many countries are paying attention to the relationship(关系) between man and the country 　58 　them. In some countries they 　59 　much time as “conservation volunteers”. They plant trees and help to 　60 　wild birds and animals.

But everyone, not only young people, must work to save our world.
