...response to the growing problem, the Environmental Protection Agency (EPA) - along with several other federal groups and the governments of states that feed into the Mississippi - released a plan of attack on Monday to reduce the Gulf's dead zone. The plan, an update of an effort launched in the waning days of the Clinton Administration in 2001, looks to harness state and federal action to reduce the flow of fertilizer into the Mississippi, much of which comes from agricultural sources that aren't covered by the regulations of the Clean Water Act. The ultimate goal is to shrink...
...million tons of nitrogen, phosphorus and other fertilizers to boost their crops, and all those chemicals have consequences far beyond the immediate area. When the spring rains come, fertilizer from Midwestern farms drains into the Mississippi river system and down to Louisiana, where the agricultural sewage pours into the Gulf of Mexico. Just as fertilizer speeds the growth of plants on land, the chemicals enhance the rapid development of algae in the water. When the algae die and decompose, the process sucks all the oxygen out of the surrounding waters, leading to a hypoxic event - better known as a "dead...
...dead zone's wake. The U.S. is not alone in grappling with this aquatic byproduct. As modern, chemically intensive agricultural practices spread around the globe, so does hypoxia; a 2004 U.N. report documents nearly 150 dead zones globally. But none compare to the black hole in the Gulf of Mexico. "This year would be the largest since we've started keeping records," says R. Eugene Turner, a zoologist with LSU who led the modeling effort. "It's definitely getting worse...
...that it's an easy one to fix. Most of the nutrient pollution that ends up in the Gulf comes from the hundreds of thousands of farms in the Midwest. The only sure way to shrink the dead zone is to reduce the amount of fertilizer running off those farms. But thanks in part to the push for corn-based ethanol and the skyrocketing price of food crops, U.S. farmers are planting more acres for corn than they have since World War II - including 15 million more acres last year than in 2006. Although there are measures farmers can take...
...farm bill, which recently passed Congress over President George W. Bush's veto, will only worsen the problem. And even if we can begin to reduce the future flow of fertilizer, repeated dead zones are having a cumulative effect, with smaller amounts of nitrates and other chemicals in the Gulf having a larger hypoxic impact than in the past. "We have to decide how much we're willing to spend to save the Gulf fisheries," says Daigle. "Right now, we don't seem to be willing to invest much." Put simply, the Gulf is running...
