Eutrophication

Eutrophication is a general term describing a process in which nutrients accumulate in a body of water, resulting in an increased growth of organisms that may deplete the oxygen in the water; i. e. the process of too many plants growing on the surface of a river, lake, etc.

, often because chemicals that are used to help crops grow have been carried there by rain.
Eutrophication may occur naturally or as a result of human actions.
Manmade, or cultural, eutrophication occurs when sewage, industrial wastewater, fertilizer runoff, and other nutrient sources are released into the environment.
