Many large farms produce zilch. They have been put into a 'land bank' where the Fed Government pays the 'farm' owner to do nothing. As a Nation, we must stop building on the most prosperous property and move our developments and suburbs to the least desirable land, land that does not produce. We must realize that anything produced by man must first be made by nature. Why are we fouling our oceans by dumping our waste in them. Why not find a way to 'compost', grind, chop, or otherwise find a way to return these materials to the land from which they came? Any plant can be grown in any part of a building: where natural light is not available, artificial (grow-) light can take its place. How many buildings stand vacant in any large city? Urban blight could be turned into urban renewal by anyone with the common sense to organize a WORK detail instead of a bread line.
