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. | |||

Thirty years ago, Lake Ponkapog in Hartwell, New Jersey, was full of life. Many birds and animals lived beside the water. which was full of fish. Now there are few birds, animals, and fish. The lake water is polluted (污染的). It is in a colour of dirty brown, and it is filled with strange plants. How does this happen? First we must think about how water gets into Lake Ponkapog. When it rains water comes into the lake from all around. In the past there were forests all around Lake Ponkapog so the rain water was clean. Now there are many homes around the lake. People often use chemicals (化学品) in their gardens. They use other chemicals inside their houses for cleaning or killing insects (昆虫). There are also many businesses. Businesses use chemicals in their machines or shops. Other chemicals fall onto the ground from cars or trucks. When it rains, the rain water picks up all the chemicals from homes and businesses and then carries them into the lake. They pollute the water and kill the animals. Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats. But oil and gas (油和汽) from boats often get into the lake. So more bad chemicals go into the water this way. People in Hartwell are worried. They love their lake and want to save it. Will it possible? A clean lake must have clean rainwater going into it. Clean rainwater is possible only if people are more careful about chemicals at home and at work. They must also be more careful about gas and oil and other chemicals on the ground. And they mustn"t use motorboats any more on the lake. All these may change people"s lives. Only then can Lake Ponkapog be a beautiful, clean lake again. | |||
