水资源短缺雅思作文

  篇【1】:水资源短缺雅思作文

  Since the beginning of time, water has been shaping the face of the earth. Water sustains human life,our environment and our cultures. But the global demand for water is increasing and the destruction of water-dependent ecosystems has accelerated.

  From my point of view, the main reason of scarcity of water resource is the rapid population growth,especially in developing countries. In order to meet the great demand for water, people exploit water resource in various ways. Water supply sources are being stretched to their limits. And surface and groundwater pollution is increasing rapidly. Research indicates that over 1 billion people still do not have access to safe water supplies and over 1.7 billion do not have access to adequate sanitation facilities.

  Another reason is the development of industry and agriculture. In some developing countries, some private factories make use of water resource low-efficiently and make much pollution. Irrigated agriculture also contributes to water scarcity. Despite the high yield, irrigation is extremely water intensive. It takes about 1,000 tons of water to grow one ton of grain and 2,000 tons to grow one ton of rice.

  Finding solutions of the problem involves the increase of worldwide awareness and international cooperation. Every individual should realize water crisis and save water. As to the government, some effective measures should be taken, including erecting modern irrigation systems and increasing the number of sewage water recycling plants. Building more dams can also be an effective solution. Dams play an important role in detaining the surface rain water flowing from the mountains and would prevent the loss of rainwater straight into the sea.

  篇【2】:水资源短缺雅思作文

  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 (灾难)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.
