What are the environmental benefits (supposedly) of biofuel? The name 'biofuel' certainly sounds green enough. Is it? Anyone?

As I uderstand it (and Hulkrogan is alluding to this) is that in order to grow large amounts of corn or wheat to run a biofuel refinery, you need a massive amount of crop space. In order to attain a profitable yield on a crop that large you're going to need large amounts of fertilizers, which are derived from oil.
In essence, once you factor in transportation, refinement and cultivation (all of which use oil) you're better off using gasoline than biofuel.
