Water is the source of the life, it dominates the survival and development of all things on earth. Preventing water pollution, guaranteeing the water safety, is environmental protection priority at this stage.Since the industrial revolution in the late nineteenth century, the industrial structure and lifestyle changed dramatically, which caused pollution that are large in quantity and various in nature. The water usage also rapidly increased, and the amount of waste water and material increased every year. As the country became more industrialized, the urban area expanded and population density increased. In the high density area, various pollutant rapidly destroyed the environment. Each government has always attached great importance to the prevention and control of water pollution, putting it in the overall development of the national economy to research and management. However, there is a big difference between hope and reality. After the local government system was adopted, the loc scope of legal system based on the classification of water pollution, and find out the defects of the scope in the water pollution control laws system ,and then according to the classification of water pollution to construct .The water pollution issues not only concerns our generation but the many generations to come. It is deeply related to our existence and once destroyed, it is almost impossible to recover. Moreover, the recovery takes a long period of time, and to recover the environmental destruction caused by the reckless development, it takes a lot more than the profit gained from the development. The environmental destruction must stop before it is too late, and the unpolluted river and lakes must be preserved better.I think that to solve water pollution, most of all, we have to know that why does water pollution occur? The reason why I think about water pollution is about this. The factors causing environmental pollutions may be manifold; increase of population, concentrationhe 8 followings. To reinforce the water pollution regulations, facilities for waste water from the living should be constructed and economic pressure should be expanded. To eliminate the inefficiencies, a centralized water management system is required. As the chemical used in the agriculture and wastes from the ranches causes water pollution, an environmental farming must be suggested and the related regulation should be adopted. Artificial marshes can be utilized so that the polluted water can be purified by the land in the process. The requirement of establish newly for reduction of environmental pollution. A financing problem should be dealt with. Infrastructure investment should be made as the capacity of existing facility is too small to handle the amount of polluted water. The recognition of water resources should be changed. Finally, to deal with the regional imbalances in the water supply and prevention of water pollution, local governments should cooperate. An effort should aes of sewage by the easiest way In each household, soap and soapy water is the biggest cause of water pollution. So, we should use natural detergent instead of synthetic detergent, which is known to be the main culprit behind water pollution. Because synthetic detergent is not only hard to break down by microorganisms, but also to be unclean water which makes the clean water rot. So it is recommended that do not use.And Wash the dishes without dishwashing, wipe the grease once with a toilet paper and then clean it up. It is also one way to remove oil stains from flour, fruit, and oil. Using this method, our water can be much cleaner.In addition, waste water from corporations, factories, and congratulatory telegrams can not only affect people but also plants and plants. Therefore, the government should strictly monitor the waste water that leaks. In fact, the pollution from these wastes causes a small or large number of problems. In 2007, a company in Korea released waste water from theparation campaign.If there are insufficient purification facilities, there will be many households or businesses to act irresponsibly. Therefore, the government will have to pay keen attention to expanding the water supply and purifying water and managing water quality. Recently, drug is not separated properly. So, there is a lot of water pollution due to medicines such as antibiotics. Thus, professionals have to handle these things.Also, it is important to conduct regular campaigns for citizens ' awareness of the situation about this water pollution, and should be implemented through cooperation with the government and each group. And, cleaning water tank is also helpful for cleaning water pollution. Then, we can have clean water environment and a healthier living.Finally, in order to prevent serious water pollution, I made the rule that called “five commendations of life” which is that everyone has to think about it all the time.1. Never throw away trash, cigarette butts on the streere.
