The four basic natural resources are water, air, land and energy. We need water for multiple uses and a certain quality is required. Its use leads to the generation of wastewater that can cause an impact on the environment. Water scarcity and pollution has become one of the most important issue in recent years. For today, both fresh water and wastewater, either for reuse or disposal in the environment will be discussed and showed in the presentation. Approximately 300 million nationwide have no access to clean water. Furthermore, over 700 million Chinese drink fetid water below World Health Organization standards. Almost 90% of underground water in cities are affected by pollution and 80% of China’s rivers fail to meet standards for fishing. Actually, all of the nation's rivers are considered polluted to some degree, and half of the population lacks access to clean drinking water. Ninety percent of urban water bodies are severely polluted. As you know, people depend on water to live on. They should be involved in finding a solution to this problem. I think, certain counter measures need to be taken as soon as possible. To begin with, the governments of all countries are supposed to formulate rules and regulations to deal with the pollution problem. In addition, factories in towns and cities must be prohibited from draining waste liquids into rivers before they are totally treated and purified. I feel if they violate relevant rules or laws, they should be fined heavily. As far as the future prospect is concerned, I am sure that good results will be achieved in this respect. Rivers which used to be contaminated by industrial wastes will be cleaned. To conclude, its obvious that people will see a brighter future only based on our hardwork to seek the suitable solutions and to make our real moves towards the problems. 本文来源：https://www.wddqw.com/doc/f9e98d292f60ddccda38a0c6.html
