Eutrophication is one kind of A. Air pollution B. Water pollution C. Soil pollution D. Sound pollution

Eutrophication refers to an increase in nutrients, especially nitrogen and phosphorus, which leads to an explosive increase in the growth of algae, called algal blooms. Eutrophication also includes the increased input of sedimentary material. There are two types of eutrophication: Natural and Cultural. In simple words, Eutrophication is a kind of Water pollution. Agriculture is a major contributor to nitrate pollution of freshwater; up of half of the nitrogen applied to crops is lost to groundwater. The loss of nitrate from agricultural land is largely caused by erosion. The other main source of agricultural eutrophication is livestock farming.
