参考答案: Water Shortage in China
With the growth of population and development of modern industry, water shortage has become a growing concern for Chinese government and people. This problem is at its worst in Northern China, especially in big cities such as Beijing, Tianjin, Shenyang and so forth.
Several factors contribute to this problem. First of all, water supplies are being consumed by a growing number of heavy industries. Also, as the population keeps growing at a steady rate, the amount of water consumed by them is naturally increasing too. Deforestation at the upper reaches of rivers has made the situation worse for the well-developed root system of trees can keep the water from diffusing into the earth. For example, the Yellow River has been out of currents for several months each year for the past few years.
To solve the problem, we still have some options. First, we must economize on the use of water resources and practice a recycling policy. Secondly, stiffer laws and regulations should be imposed to protect the limited water resources we have. Also, more diversion projects should also be used so as to direct the surplus water resources in Southern China to the under-supplied regions.
