Since the beginning of time, what has been shaping the face of the earth, what assistance human life or environment and our cultures, but global demand for water is increasing, and destruction of water dependent equal system has accelerated.
From my point of view, the main reason of scarcity of water resource, is the repeat population growth, especially in developing countries, in order to meet the great demand for water, people exploit water resource, in various ways, water supply source has been stretched to the limits, and surface and ground water pollution is increasing rapidly, research indicates that over one billion people still don't, have access to save water supplies, and over one point seven billion don't have access to adequate sanitation facilities.
Another reason is the development of industry and agriculture, in some developing countries, some private factories make us of, water resource low_efficiently And make much pollution, irritated agriculture also contributes to water scarcity. despite the high yield, irrigation, extremely water intensive, takes about one thousand tons of water to grow one ton of, green and two thousand tons to grow one ton of rice,
finding solutions of the problem, in most increase of worldwide awareness, and international cooperation, every individual should realize what crisis and save water, as to the government some effective measures, should be taken, including directing modern irrigation systems, and, increasing the number of switch water recycling plants.
Building next dams can also be an effective solution.
