At the bottom of the Gulf of Mexico in America came area unfit for living all sea inhabitants. Abnormal phenomenon connected with the work of man. The abnormal area of the Gulf of Mexico, the aforementioned "dead zone" occupies an area of about 13 thousand square kilometers On this entire submarine areas disappeared life, marine life cannot live in this area, because water has remained little air. This stretch of water were examined by scientists from the Institute of Louisiana, who concluded that this anomaly has happened in the result of human work. According to reliable information environmentalists, site of a bottom, in his own size approximately equal to the American state of Connecticut, almost completely overgrown with algae that consume virtually all of the air in the water, making it unfit for living shrimp and fish, tells ITAR-TASS. Scientists believe that the main reason for the origin of the anomaly is extensive farming activities in the area of water area. Farms located near the coast, vigorously use powerful chemical fertilizers that rains and rivers drain into the Bay. It vossozdaet unusually favorable conditions for benthic vegetation that "steal" all the air in marine inhabitants. This phenomenon, as have informed the South American environmentalists, it happens almost every summer. In the current quarter "dead zone" somewhat less than in previous decades. So, in 2002 it reached 21 thousand km, which is equal to the area of Massachusetts. "This is the brightest example of how we abuse our available resources," said ecologist from the Institute of Louisiana gene Turner. Now "dead zone" in the Gulf of Mexico is 2 by area in the world. 1st place belongs overgrown with algae area of the seabed in the Baltic sea near the coast of Finland. Globally, there are over 550 seats, which regularly occur similar phenomena. Their number constantly increases.
