1970 was World Conservation (保护) Year. The United Nations wanted everyone to know that the
world was in danger. They hoped something could be done.
Here is one example of the problem. At one time there were 1,300 kinds of plants, trees and flowers
in Holland (荷兰), but now only 866 are left. The others have been destroyed (毁灭) by modern people
and their science. We are polluting earth, air, water and everything around us. We can't live without
these things. If things go on like this, we shall destroy ourselves.
What will happen in the future? Perhaps it's more important to ask "What must we do?" More and
more young people have known this. Many of them are helping to save our earth. For example, they plant
trees. 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 conversation through a song called "No one's going to change our
world". It was made by Cliff Richard and other singers. The money from it will help to conserve tigers,
elephants and pandas on the earth.
