The corn used for animal feed is also used in a vast amount of consumer food products. While we eat sweet corn, the dimpled stuff is what gets turned into HFCS. Food is cheap because HFCS is cheap.
I think the real issue is unsustainable farming practices. The Ogallala water table is being quickly depleted, excess nitrates and other nutrients are creating dead zones in the Mississippi Gulf, and virgin land is being cleared to support an industry that can't possibly hope to make a dent in energy use.
Based on the amount of water, energy, and land needed to grow crops, biofuels will be nothing more than a tiny piece of the energy collage. It'll make a few rich farmers richer, though.
