Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. Water pollution is a large set of adverse effects upon water bodies (lakes, rivers, oceans, groundwater) caused by human activities.
Water pollution is caused due to several reasons. Here are the few major causes of water pollution:
Sewage And Waste Water: Sewage, garbage and liquid waste of households, agricultural lands and factories are discharged into lakes and rivers. Dumping: Dumping of solid wastes and litters in water bodies causes huge problems. Litters include glass, plastic, aluminum, styrofoam etc. Different things take different amount of time to degrade in water. They affect aquatic plants and animals.
Effects of water pollution are the contamination from pesticides causes reproductive damage within wildlife in ecosystems. Sewage, fertilizer, and agricultural run-off contain organic materials that when discharged into waters, increase the growth of algae, which causes the depletion of oxygen.
•Chain of Destruction
When polluted water is found in our ecosystem, it leaves a trail of destruction. Polluted water that ends up in local streams and rivers will damage the life in and surrounding it. Vegetation that feeds on this water for survival can be damaged and killed from polluted streams. Farming
Many people won’t put much thought in to pollution until it starts to affect them personally. Water pollution can – and will – do this. Farms can suffer as a result.
•Illness in Humans
One of the greatest dangers on a family beach vacation is bringing home unwanted illness. Ear aches, pink eye, gastroenteritis, respiratory infections, as well as Hepatitis can all be transmitted through polluted beach water.
