Learn about eutrophication

Eutrophication is the process by which a body of water acquires a high concentration of nutrients, especially phosphorus and nitrogen. These typically promote excessive growth of algae. As the algae die and decompose, oxidation of this organic matter and respiration by the decomposing organisms can deplete the water of available oxygen, causing the death of other organisms, such as fish. Eutrophication is a natural, slow-aging process for a water body, but human activity sometimes greatly speeds up the process.

The term "eutrophic" means well-nourished; thus, "eutrophication" refers to natural or artificial addition of nutrients to bodies of water and to the effects of the added nutrients. When the effects are undesirable, eutrophication may be considered a form of pollution.
