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 factories and treated sewage water is used for irrigation in farming land.

人们无法想象没有水的生活。没有它,我们生活在地球将会是一个死一个。就没有树木,没有庄稼,没有动物,没有人。因此水被认为是氧气的重要性。

虽然近四分之三的地球表面覆盖着水,海水是不能饮用的。对水的需求不断增加,水资源稀缺。农业生产需要大量的水,那么产业。此外,人口的快速增长使得人们越来越难生存,因为缺水。所以缺水已经成为最严重的问题之一。

庆幸的是,人们已经意识到这个紧迫的问题,并试图找到方法来缓解它。首先,人们呼吁节约用水。第二,采取各项措施,保护水资源。第三,循环水用于工业用途,在工厂和处理过的污水用于灌溉的农业土地。
