From The Wall Street Journal:
For more evidence, consider the ethanol waiver requested by the hunger charity ActionAid and the free-market Competitive Enterprise Institute. Normally when making decisions, the EPA considers "impacts on human health," a nebulous measurement that it usually inflates to justify costly regulation. But the ethanol rules mention health only to minimize the danger, despite numerous peer-reviewed studies showing that biofuel mandates increase hunger and hunger-related diseases at home and abroad and contribute to tens of thousands of annual deaths. The EPA still hasn't responded on the merits.
