World food crisis

We're now getting into the cruel choice, the dilemma, the difficult choice between using corn as a human and cattle food or to converte them to bio energy as green oil.
Of course, the world will be divided into the pro's and con's, the rich countries sponsored by the US will, obviously, choose the green oil to support their life style, on the contrary the poor countries will favor corn for human and cattle food.
The soaring price of oil recently has triggered the idea of replacing fuel cells to green oil, produced from corn. This plan, which was proposed by the US President would like to replace 30% consumption of gasoline in the US by bio energy produced from corn.
This plan indicates that the US is preparing an ambitious, large scale and massive project to converte corn, which is originally consumed by both human and cattle, into green oil to substitute its fuel cells consumption.
