President Obama sees the oil spill as a chance to make the planet a greener place by weaning us off fossil fuels and pushing us toward alternative energy. The earth and the Gulf of Mexico have indeed been getting greener lately, thanks to agricultural runoff due to a mandated surge in biofuels such as ethanol.
Before the first gallon gushed from Deepwater Horizon, there existed an 8,500 square mile “dead zone” below the Mississippi River Delta, roughly the size of Connecticut and Delaware combined.
Hypoxia, or oxygen depletion, caused by agricultural runoff in the Mississippi River Basin varies from year to year, but it has been on an upward trend as acreage for corn destined to become ethanol increases.
