The problem is that the world is consuming more cereals than it produces — partly because of more mouths to feed, partly because of the ever-increasing demands of livestock as countries like China clamber up the protein chain from rice to hamburgers. It takes 7 pounds of cereal to produce one pound of beef. About 750 million tons, over a third of the world’s cereal crop, goes to feed livestock. Humans eat only 1.006 million tons, less than half the total crop.
