Eutrophication Has Greek Roots

Eutrophication, which comes from the Greek eutrophos, "well-nourished", has become a major environmental problem. Nitrates and phosphates, especially from lawn fertilizers, run off the land into rivers and lakes, promoting the growth of algae and other plant life, which take oxygen from the water, causing the death of fish and mollusks. Cow manure, agricultural fertilizer, detergents, and human waste are often to blame as well. In the 1960s and '70s, the eutrophication of Lake Erie advanced so extremely that it became known as the "dead lake". And many areas of the oceans worldwide—some more than 20,000 square miles in extent—have become "dead zones", where almost no life of any kind exists.

Keely Larson, Ars Technica, 20 Aug. 2022 Low levels of oxygen (hypoxia) or no oxygen (anoxia) can occur when excess organic materials or nutrients enter water bodies (and result in occurrences such as eutrophication).

Quartz, 19 July 2022 Meanwhile, an uptick in farming, industry, and urban development has fed eutrophication – an increase in biomass and algae that deoxygenates water and accelerates erosion.

Erika Page, The Christian Science Monitor, 27 Aug. 2021 But studies have shown that eutrophication reduces the abundance of Atlantic croaker and affects the price of shrimp; both are important commercial species.

Sarah Kaplan, Twin Cities, 11 June 2019 The decay process of algae uses up the oxygen in a process called eutrophication, Levin said.

Sydney Pereira, Newsweek, 5 Jan. 2018 If the phytoplankton blooms are too large, this can lead to eutrophication, when oxygen is lost from the water and kills marine life.
