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 1300 plants and flowers in Holland, but now
only 866 are left. The others have been destroyed (毁坏) by modern man and his science. We are changing
the earth, the air and the 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 is more important to ask "What must we do?" More and more
young people have known this. Many of them are helping to save our world. For example, they plant trees. In
a small town in the USA a large group of girls cleaned the banks of 11 kilometres of their river. Young people
may hear about conservation 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.
