1970 was World Conservation(±£»¤) Year. The United Nations wanted everyone to know that the world is in danger. They hoped that governments(Õþ¸®) would act quickly to conserve nature(±£»¤×ÔÈ»). 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 his technology. We are changing the earth, the air, the 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 about conservation through a record called ¡°No one is 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.

Here is a page from a magazine named Future. Read the following information about things that may happen in ten years.
A
Cars will run on solar power or electricity and will be much cleaner. They will be much safer. For example, if you are too close to another car or if you are driving dangerously, your car will slow down by itself.
B
Because there won¡¯t be any spare land, new cities will have to be built in the sea. Some cities on water will have two levels. People will live on the upper level; the lower level will be used for traffic, shops and factories.

Biotechnology(ÉúÎ﹤ÒÕѧ) will make food better and healthier. Plants that are not affected by insects or illnesses will be developed. The taste of fruits and vegetables will be better and food will be kept longer.
D
New technology will be used to make TVs that are only 5cm thick. They will have pictures that are as clear as photos. Electrical appliances(É豸) will be quieter and will be controlled by computers; they will also use 50% less power.
E
Many new ways to cure illnesses will be successful by using products of genetic engineering. Cures will be found for the flu and the common cold. However, some new illnesses will appear.
