The real dead zone is that swath of the Gulf choked with Soylent Green - because it's made of people!

Growing more corn to meet the projected U.S. demand for ethanol could worsen an expanding “dead zone” in the Gulf of Mexico that is bad for crawfish, shrimp and local fisheries, researchers reported on Monday.
The dead zone is a huge area of water — some 7,700 square miles — that forms above the continental shelf of the Gulf of Mexico every summer. It contains very low levels of oxygen.
The dead zone starts in Midwestern corn country when farmers fertilize their fields with nitrogen. The fertilizer run-off flows down the Mississippi River into the Gulf of Mexico, making algae bloom on the surface and cutting oxygen to creatures that live on the bottom.
The low levels of oxygen in the zone make it difficult for crustaceans and bottom-feeding fish to survive, said Simon Donner, who worked on the study published the Proceedings of the National Academy of Sciences.
Crustaceans will likely struggle to stay alive, Donner said by telephone. Fish will swim out of the zone, potentially devastating local fisheries, he said.
“We’re already at a point where recommendations have been made that nitrogen levels in the Mississippi River have to decrease by up to … 55 percent in order to shrink the dead zone,” said Donner, of the University of British Columbia in Vancouver.
“And now with this incentive to produce more corn and use more fertilizer, we’re pushing in the other direction,” Donner said. “The two policies are just completely incongruous.”
The change candidate, while pretty good on the environment, is nonetheless a big supporter for getting creative with corn.
