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.
