We in the Chesapeake Bay watershed are not the only ones dealing with large dead zones caused by agricultural waste like nitrate- and phosphate-containing fertilizers, and other toxins including sewage runoff, animal waste and car exhaust.
A recent article in E – The Environmental Magazine states that scientists predict a “dead zone” in the Gulf of Mexico could expand to between 8,500 and 9,421 square miles this year, roughly the size of New Jersey and Delaware combined. Dead zones are oxygen-depleted, lifeless expanses of water. The dead zone in the Gulf, 60 miles off the coasts of Louisiana and Texas, is one of the largest in the world and has more than doubled since the 1980s. In 2002, a staggering 8,400 square miles of the Gulf was “hypoxic” or lacked sufficient oxygen for most marine life to live.
