Water scarcity Nowadays, we are facing the threat of water scarcity. This essay will discuss the reasons behind that, and think about how to solve it. With the growth of population, the demand for water resources is tremendously increasing. Whatever agricultural, industrial, or domestic use of water has been rising at a dramatic rate. At the same time, some rivers, lakes, and seas are suffering pollution from frequent human activities. Also, improper use of water can be seen everywhere. Huge amounts of water are wasted by factories, farms, and families every day. Therefore, we should take some measures to solve the problem. The government should control the population growth rate for sustainable development. Meanwhile, those factories or individuals who cause a lot of water pollutants should be punished at heavily fined. As a citizen, we should try to more cherish water by doing things as simple as reusing the dirty water to flush the toilet, turning off the tap when we are brushing our teeth, etc.. And educational department should emphasis the shortage of freshwater, and make students care more about the use of water and reduce waste of water. In addition, scientific research on desalination technology should be encouraged and funded more. For example, scientists can focus on translating seawater to freshwater. In conclusion, there is a range of reasons for the lack of fresh water, such as the growth of population, water pollution, and the arbitrary use of freshwater resources. We should take some steps to ease the issue, like control the population growth rate, promote the academic research on alternative sources of freshwater, and most importantly, do some simple things to reduce the waste of water by ourselves.
