This chart is a crock, and the first clue is the UN label down at the bottom. As has been discussed, only 10% of yellow dent corn is consumed directly as human food in any way, shape or form. That amount has not been reduced as a result of ethanol production. You could argue that the corn could be fed to hogs and humans could eat the hogs. Problem there is that the spent mash from ethanol is already fed to hogs as a high protein suppliment. Besides, most of the people who wring their hands about ethanol induced starvation object to animal agriculture also.
