On Water Shortage
No one can have failed to notice the fact that water shortage is a grave problem with which the whole world is confronted. Actually, it has become so widespread that it has severely affected people’s daily life and hindered the development of the global economy.
A number of factors could account for the problem, but the following might be the critical ones. To begin with, with the development of agriculture and industry, an increasing amount of water is needed. In addition, the ever-increasing population is another leading cause of water shortage. Besides, the global tendency of warming up also contributes to the problem. What’s worse, pollution and waste of fresh water aggravate the situation.
In view of the seriousness of the problem, effective measures must be taken before things get worse. First, it is essential that laws and regulations be worked out and enforced to protect water resources. Secondly, people should enhance their awareness of saving water. With these measures taken, it is reasonable for us to expect a brighter future.w
