      A quote:

      > costly than first thought.

      > 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

      > Moreover, the report says that biofuels will likely make the
