eutrophication
YOO-truh-fih-KAY-shun
/ˌjuːtrəfɪˈkeɪʃn/
Excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.
A 'too much of a good thing' scenario where excess nutrients (like nitrogen) lead to 'dead zones'.
The story behind the word. Derived from the Greek 'eutrophos', meaning 'well-nourished'. While it sounds positive, in ecology, it describes the harmful over-feeding of an ecosystem.
Commonly confused with
- hypoxia: Hypoxia is the low-oxygen state that results from eutrophication.

Memory hook
'Eu' (Good) + 'Troph' (Food) = Too much food! Eutrophication = Nutrient overload.
When not to use
Do not use for simple water pollution; it specifically refers to nutrient enrichment.
Fun facts
- Eutrophication can occur naturally over centuries, but human activity (cultural eutrophication) speeds it up to just decades.
