By Joel Achenbach, Washington Post, August 15, 2008. "In the latest sign of trouble in the planet's chemistry, the number of oxygen-starved "dead zones" in coastal waters around the world has roughly doubled every decade since the 1960s, killing fish, crabs and massive amounts of marine life at the base of the food chain, according to a study released yesterday ... Low oxygen, known as hypoxia, is in significant measure a downstream effect of chemical fertilizers used in agriculture. Air pollution, including smog from automobiles, is another factor. The nitrogen from the fertilizer and the pollution feeds the growth of algae in coastal waters, particularly during summer."
