Water is one of the basic human needs.  Firstly, water pollution coming from chemical and industrial processes. When factories pour their chemicals and livestock wastes directly into rivers, the water becomes poisonous and oxygen levels are depleted causing many aquatic organisms to die. After that, cause of water pollution is from pesticides. Farm pesticides poison aquatic plants and animals. Animal manure, chemical fertilizers, pollutes water by supplying excess nutrients. It can be effect decreasing the amount of oxygen level in water causing the death of many aquatic organisms.
