What is cultural eutrophication?

Cultural eutrophication is a process that occurs when human water pollution speeds up by introducing sewage, detergents ,fertilizers and other sources of nutrients in an aquatic ecosystem. 

This form of eutrophication has an impact on freshwater resources, fisheries and other bodies of water that will ultimately be a cause of degradation in the aquatic ecosystem. 

Cultural eutrophication that affects aquatic ecosystems shows signs of extremely low oxygen concentrations in bottom waters. This condition is known as hypoxia.
