　　It is widely believed that fresh water will never be used up due to its rich resources such as rain, rivers and wells. In fact, such belief is unfortunately wrong and possibly dangerous. As is depicted in the picture, we are facing serious shortage of fresh water, especially in the northern part of China. The land in some areas has become barren and there is no water coming from the pumps. Definitely, the picture reminds us of the serious situation we are confronting.

　　Short as it is, people still waste it. With the growth of population and industry, the amount of fresh water in use is also growing rapidly. It is estimated that if not controlled, fresh water will be used up by the next century. Another dangerous factor is the water pollution, which aggravates the seriousness of fresh water shortage.

　　It is no use only being aware of the shortage of fresh water. It is never too late if we act right now. The first important measure is to protect our water resources form being polluted. Educating people to save water in daily life is of similar significance. Techniques such as recycling waste water and converting sea water into drinkable water are especially needed in dry areas. It is only when these measures are put into practice can the shortage of fresh water be solved.
