Earth First! Earth First! is a radical environmental advocacy group that emerged in the Southwestern United States in 1979. It was co-founded on April 4, 1980 by Dave Foreman, Mike Roselle, Howie Wolke, Bart Koehler, and Ron Kezar.
A eutrophic body of water, commonly a lake or pond, has high biological productivity. Due to excessive nutrients, especially nitrogen and phosphorus, these water bodies are able to support an abundance of aquatic plants. Usually, the water body will be dominated either by aquatic plants or algae.
Eutrophication happens as water bodies, such as estuaries, slow-moving streams and lakes, receive excess nutrients that trigger excessive plant growth. This increased plant growth, often referred to as an algal bloom, reduces the amount of oxygen dissolved in the water when dead plants decompose and cause other organisms to die.
