Here's a little cherry-picking of data:
EPA Administrator Lisa Jackson said the analysis shows corn ethanol emitting 16 percent less greenhouse gases than gasoline, even taking into account global future land-use changes.
But that's true in only in one of the scenarios the EPA examined; another showed corn ethanol would account for 5 percent more greenhouse gases than gasoline. The scenario Jackson cited assumes future environmental benefits over a period of 100 years will more than pay back the initial increase in greenhouse gases from land use changes.; the second assumes a shorter payback period of 30 years.I might add that there are any number of reports that indicate ethanol is a loser on all accounts. Google "ethanol energy balance" to see what I mean.
Let's force an end to this debacle. Call your congressman and senators. Tell them to leave the food supply alone.
