People can't imagine life without water. Without it, the earth we live on would be a dead one. There would be no trees, no crops, no animals and no people. So water is considered to be next to oxygen in importance.
Although nearly three quarters of the earth's surface is covered with water, it is sea water and undrinkable. The demand for water is increasing, while water resources are scarce. Agricultural production needs enormous amounts of water, so does industry. Besides,the rapid growth of population makes it more and more difficult for people to survive because of the water shortage. So water shortage has become one of the most serious problems.
Fortunately, people have realized this pressing problem and are trying to find ways to salve it. First, people are urged to economize on water. Second, measures are taken to protect water resources. Third, circulating water is used for industrial purposes over and over in factovies and treated sewage water is used for irrigation in farming land.

[范文]
Presently, the world is faced with serious water problems. But these problems witt become more intense and more complex in the future. Our increasing population witt tremendously increase urban waters, primarily sewage. On the other hand, increasing demands for water witt decrease substantially the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complex chemical processes will produce large volumes of liquid wastes. Many of thesewitt contain chemicals that are poisonous. To feed our rapidly expanding population, agriculture will have to be intensified. This will involve ever increasing quantities of agriculture chemicals. From this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problems.
There are two ways by which these pollution problems can be lessened. The first relates to the treatment of wastes to decrease their pollution hazard. This involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes to permit the reuse to the water or best reduce pollution upon final disposal. The second approach is to develop an economic use for all or part of the wastes. Farm manure is spread in fields as a nutrient. Wastes from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Liquid wastes from other processing plants may also be used as a supplemental source of water. Only by doing these promptly now can we expect to solve the serious water problems in the future.
篇三:水资源的英语作文人们总以为淡水是取之不尽的,实际上淡水资源是很有限的。请谈谈你的看法。
It is generally believed that there is a good supply of fresh to our disappointment,the fact is just the opposite.
As we can see,the world population is growing rapidly day by enough fresh water is needed to feed such a big population. What's more,with the development of industry,factories and vehicles produce poisonous gases or wastes,which consequently results in the pollution of water. Though fresh,a good amount of it can no longer be used. Only quite limited fresh water resource is available to human beings. So it's high time for us human beings to take quick action to protect water pollution and save water,otherwise,we cannot survive on the earth.
With fresh water,the world will be prosperous.
