Ethanol and the Gulf Dead Zone
- A quote:
> Shrinking that dead zone in the Gulf of Mexico will be much moreAnd the link:
> costly than first thought.
> A group of scientists that looked at the problem during the Clinton
> administration targeted agricultural runoff in the Midwest as the
> main source of the problem and called for a 30 percent reduction in
> the amount of nitrogen flowing into the Gulf.
> A new panel of scientists believes it's going to take a far bigger
> reduction in nitrogen than that, on the order of 45 percent,
> according to a draft report.
> And even that is not going to be enough. The scientists say that a
> second chemical, phosphorus, which comes from city sewage systems
> as well as farms, also needs to be reduced. By 40 percent.
> Moreover, the report says that biofuels will likely make the
> problem worse, because of the increase in corn acreage and use of
> nitrogen fertilizer needed to keep with the demand for ethanol.
