Eutrophication is the enrichment of an ecosystem with chemical nutrients, typically compounds containing nitrogen, phosphorus, or both.
Eutrophication can be a natural process in lakes, occurring as they age through geological time.
Eutrophication was recognized as a pollution problem in European and North American lakes and reservoirs in the mid-20th century.
Human activities can accelerate the rate at which nutrients enter ecosystems.
