Clean unpolluted water is also essential for our ecosystems. Plants and animals in freshwaters react to changes in their environment caused by changes in water quality. Many human activities results water pollutants with the main sources being discharge from urban waste water treatment and industrial effluents and losses from farming. Pollution takes many forms. Faecal contamination from sewage makes water aesthetically unpleasant and unsafe for recreational activities, such as swimming, boating or fishing. Many organic pollutants, including sewage effluent as well as farm and food-processing wastes consume oxygen, suffocating fish and other aquatic life.
