Lê Đăng Khánh tham Water sources plays an important role in every human life.It is the source of life, the precious resource of the world.But clean water is not limitless, clean water can be lost.Nowadays, water sources are being gradually polluted because of human irresponsibility.The more people litter, the worse their health becomes.Households's domestic wastewater are littered indiscriminately into rivers and lakes lead to rivers and lake are damaged and contaminated.However, the indiscriminate littering has yet to show signs of stopping.The consequences of water pollution are increasing and harming people's life.Wastewater from industrial zones is also one of the most dangerous causes water pollution.The toxicity of industrial wastes is different: those endangering human health, those with low flash points, insecticides, soil pollution ,etc.Natural disasters such as floods also pollute water resources because it schweppes soil, mud, garbage paper into ponds, lakes. In my opinion, in order to protect clean water, every family must have awareness to protect water - protect themselves.To limit water pollution affect health, each family must have simple and effective water treatment measures.Each person must also take appropriate measures to reduce water pollution.The environmentalists have proposed specific measures to combat water pollution, such as: Raising awareness of the community not to throw waste indiscriminately ; do not use fresh manure as fertilizer; using pesticides according to instructions; Reduce waste when using water in daily activities.In my village, there are many young volunteers propagate measures to prevent water pollution and they ask the people in the village to use water protection measures to protect people's lives.I hope that the water source will not be polluted, Water protection measures will prevent people from destroying water sources!
