                                                          The World's Water Shortage
     The world is not only hungry, but it is also thirsty for water. This may seem strange to you, since nearly    70 percent (百分比) of the earth's surface is covered with water. But about 97 percent of this huge
amount is sea water, or salt water. Man can only drink and use the other 3 percent the fresh water from
rivers, lakes, underground, and other sources (资源). And we cannot even use all of that, because some
of it is in the form of ice-bergs and glaciers (冰川). Even worse, some of it has been polluted.
     However, as things stand today, this small amount of fresh water is still enough for us. But our need for water is increasing (增加) rapidly almost day by day. Only if we take steps to deal .with this problem
now can we avoid (避免) a severe (严重的) worldwide water shortage later on.
     We all have to learn how to stop wasting our valuable water. One of the first steps is to develop ways
of reusing it. Today in most large cities, water is used only once and then sent out into a sewer system (下水道). From there it returns to the sea or runs into underground storage tanks. But it is possible to pipe
used water to a purifying (净化) plant. There it can be treated with chemicals so that it can be used again,
just as if it were fresh from a spring.
     But even if every large city purified and reused its water, we still would not have enough. All we'd have   to do to make use of the vast reserves (贮备) of sea water in the world is to remove the salt. If we take these steps we'll be in no danger of drying up.

     1979 was World Conservation (自然保护) Year. The United Nations wanted everyone to know
that the world is in danger. They hoped that governments would go into action (采取行动) quickly
in order to conserve nature. Here is one example of the problems. At one time there were l,300
different plants, trees and flowers in Holland, but now only 860 remain. The others have been
destroyed by modern man and his technology (技术). We are changing the earth, the air and the water,
and everything that grows and lives. We can't live without these plants. lf we continue like this, we will
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
that conservation is necessary. Many are helping td 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 group of girls cleaned
the banks of 11 kilometers of their river. Young people may hear about conversation' 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 wild animals.
