'Another one of those generous women once commented, “If we have an acre of corn, we mustn’t harvest it all. If we did, where would the poor find food?” If that’s not God’s providence at work, what is?'

For the most part, corn in the grainbelt is seen as a commodity to market and to profit from - the live food aspect of corn grain is little appreciated; such a dismissive attitude toward corn grain is in fact economically wasteful and costly to nature and to humankind. The practice of hot-air drying of corn grain with propane gas heat in fact introduces combustion pollutants into the mass of stored grain, in addition to the heat that degrades the food protein and starch chemistry. 
The glut of corn grain today and the plight of farmers are aggravated by toxic exploitation promoted by the petrochemical industry. With respect to provisioning food for world populations, there's a better answer than the mono-culturing corn-grain!  http://www.secondenlightenment.org/Right%20as%20Grain-1.pdf
