1970 was World Conservation (保護) Year. The United Nations wanted everyone to know that the world is in danger. They hoped that the government would act quickly 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 (剩余).The others have been destroyed by modern man and his technology. We are changing the earth,the air,water and everything that grows and lives. We can't live without these things. If things go 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 young of today. A lot of them know 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 number of girls cleaned the banks of 11 kilometers of their river. Young people may hear the song 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 animals.

Noise Pollution Stop!Listen!What do you hear? You may hear many different sounds. Some of those sounds may be noisy. Noise is loud or unwanted sound.
Noise can be caused by many kinds of machines,such as motorcycles,jet planes,tractors (拖拉機)and so on. And,to some people,rock bands also cause noise.
What happens to people living near noisy conditions? Doctors find that these people have trouble in sleeping. But most seriously,constant (持續(xù)的)loud noise can cause a loss of hearing.
Scientists measure the loudness of a sound by decibel (分貝).The bigger the number of decibel is,the noisier it will be. The sound of a quiet room,for example,measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from the traffic and some rock bands can measure over 120 decibels. Noise at this high level causes the greatest hearing loss.
