Cultural eutrophication in the Chesapeake Bay
Info: Cultural eutrophication is an increase in biological productivity and ecosystem succession caused by human activity. Eutrophication can be human-caused or natural. It is mainly caused by increased nutrient input into a water body. Eutrophication was the major cause of reductions in submerged vegetation. Due to clearing of land and building of towns and cities, land runoff is accelerated and more nutrients such as phosphates and nitrate are supplied to lakes and rivers, and then to coastal estuaries and bays.Chesapeake Bay has been the subject of intensive research on cultural eutrophication.
