It is publicly recognized that water is one of the most important resources for life. If there were no water, there would be no life. China could boast abundant water resource, with the amount totaling B,H00 billion cubic meters, however, we also have a large population of A.B billion people. If we allocate the water to each person, we must consider our country as one of severe water scareity. In some western areas of China, with little rain all the year round, the earth is cracked or decertified. People have to walk miles every day to get water. They do not have enough water for drinking, for farming or for maintaining personal hygiene, causing much inconvenience to every level of their life.

Even in the east of the country, where there is plenty of rain and there are a great many rivers and lakes, the situation does not offer reasons for optimism. Statistics shows that D00cities suffer from water shortage and the situation for about A00 is very serious. What make the situation even worse is that C0% of the rivers are polluted and waters around I0% of the cities are polluted to different extent. This has posed a serious threat not just to our health, but also to our survival. The environment has worsened to an extent where we must do something about it.

We must raise public awareness of water crisis. As individuals we should use water-saving facilities at home and reuse water from kitchen for toilet. Everyone can do something to save water. If actions were not taken immediately, the situation might be worse than our wildest imagination.
