Eutrophication

Eutrophication occurs when a body of water contains too many minerals and nutrients. This can be damaging to the ecosystems of the body of water, as it can induce excessive growth of plants and algae. It can also result in oxygen depletion of the water body. Eutrophication is often caused by detergents, fertilizers and sewage.
