It may be true that growing food is more efficient--but we don't *need* to grow that much food.The U.S. already grows far more corn than we could possibly eat. Rather than looking just at output efficiency, we should look at actual demand, and necessity.

What is grown in an area is determined by the climate and terrain. Iowa, Indiana and Illinois are flat and level, there adapted for growing grains (and they do this quite nicely). Areas like Eastern Tennessee, Arizona, Montana, Southwest Missouri, are not adapted for growing grain, and hence, you see lots of cattle browsing the countryside. Try planting wheat on the hillsides of southwest Virginia or Florida, these areas are much more adapted to growing cattle profitably than grains.
