However, the lack of awareness of environmental protection and the lack of capacity for environmental protection have led to a series of water pollution problems. The discharge of many toxic and harmful substances in agricultural production activities will have a huge impact on the ecological environment and even threaten human health and safety. For example, the improper use of pesticides and fertilizers will cause heavy metals to exceed the standard, the white cigarette ends brought about by straw burning will also become "three wastes" to enter the water body for pollution, and the irrational discharge of nitrogenous and phosphate fertilizers from livestock and poultry breeding will cause eutrophication of the water quality, and other phenomena are constantly occurring for frequent treatment, among which the deterioration of the water environment quality in rural areas is one of the important factors in our country. At the same time, it also brings serious harm to human beings: eutrophication of water bodies, soil hardening and excessive heavy metal elements, etc., which are all caused by people's lack of awareness of environmental protection and limited scientific and technological level.展开更多
