Tuning to the BBC or CNN, one is besieged by (news about) formidable disasters, diseases, conflicts, and controversies. But none is more challenging than the shortage of fresh water, a source which has long been mistakenly assumed to be inexhaustible. Unfortunately, few people realize the impending (急迫的)potential catastrophe (災(zāi)難)arising from the insufficient fresh water. Governments must be blamed if they have not informed people the importance of fresh water.

Fresh water has been closed associated with life, not only the life of human beings, but also the life of all kinds of plants and animals. Lacking fresh water, the earth will become ill. Nevertheless, human beings are confronted with the crisis of insufficient fresh water.

The shortage of fresh water can be attributed to the lower efficiency in water utilization. The irrigation in many countries wastes overwhelmingly. Some developing countries still use the primitive irrigation system, which is believed to waste at least 70% fresh water.

Life water utilization also shows strikingly lower efficiency. Many citizens have no concept of saving water. In most cities in China, fresh water is used to flush lavatories. Moreover, most citizens use wash-machine, which consumes a larger volume of fresh water.

Besides, fresh water has been polluted by agriculture and industry activities. Aquatic(水)ecosystem has largely been ruined by unrestricted drainage (排水)of sewages (污水). In metropolis (big cities大都市), the hospitals and laboratories are also the serious sources of water pollution.

Governments are expected to launch campaigns against water pollution. Individuals, households, and the states all should use their unique ways to save the limited resources.
