Drought Aids In Limiting Dead Zone There's a "dead zone" where the Mississippi River dumps into the Gulf of Mexico, creating such a low-oxygen environment that it cannot sustain life. The cause? Agricultural runoff, mostly. The dead zone has grown from 15 square miles in 1988 to 3,725 square miles present day — for reference, Connecticut is 4,845 square miles. And this dead zone has proven costly from all angles: $2.4 billion a year in damage versus $2.7 billion a year to fix it. On the bright side, though, the dead zone overall has not grown as fast as previous predictions estimated — but that's most likely due to drought which means less water is dumped into the Gulf altogether. >> Read More |
