Supposed environmental solutions often create new problems.
Dead zone in gulf linked to ethanol production
While the BP oil spill has been labeled the worst environmental catastrophe in recent U.S. history, a biofuel is contributing to a Gulf of Mexico “dead zone” the size of New Jersey that scientists say could be every bit as harmful to the gulf.
Each year, nitrogen used to fertilize corn, about a third of which is made into ethanol, leaches from Midwest croplands into the Mississippi River and out into the gulf, where the fertilizer feeds giant algae blooms. As the algae dies, it settles to the ocean floor and decays, consuming oxygen and suffocating marine life.
Known as hypoxia, the oxygen depletion kills shrimp, crabs, worms and anything else that cannot escape. The dead zone has doubled since the 1980s and is expected this year to grow as large as 8,500 square miles and hug the Gulf Coast from Alabama to Texas.
The gulf dead zone is the second-largest in the world, after one in the Baltic Sea. Scientists say the biggest culprit is industrial-scale corn production. Corn growers are heavy users of both nitrogen and pesticides. Vast monocultures of corn and soybeans, both subsidized by the federal government, have displaced diversified farms and grasslands throughout the Mississippi Basin.
“The subsidies are driving farmers toward more corn,” said Gene Turner, a zoologist at Louisiana State University. “More nitrate comes off corn fields than it does off of any other crop by far. And nitrogen is driving the formation of the dead zone.”

[…] The hysteria surrounding the BP accident (almost as if it had been intentionally engineered) has focused on the photo opportunities presented by oil-coated birds and beaches and has almost obscured the fact that 11 people were killed. The accident has been dubbed “the greatest environmental disaster ever” and has been used as evidence of the evils of technology. It has not suited the environmental “do gooders” to acknowledge that “green” activities cause more damage in the Gulf of Mexico than accidental oil spills. […]
