What is Eutrophication? Discuss the phenomenon of accelerated eutrophication.

Explanation

Eutrophication is a natural process which means 'well nourished or enriched'. It is a natural process of aging of water bodies due to rich supply of nutrients. In young water bodies water is cold, clear with moderate life forms. However, when abnormally high amounts of nutrients are released from sewage it results in excessive algal growth or bloom of microorganisms. Over the period of time because of dumping of industrial and house effluents as well as piling up of silt, the water body gradually becomes shallower, warmer, giving way to marshy plants and eventually converting into land. This phenomenon of accelerated aging of water body is called Eutrophication.
