Again, I’d like to see strong numbers of what would happen if every homeowner in the world had a “Victory Garden” of sorts out back, wherein they would grow staples, vegetables, etc. in all applicable seasons (shorter for you, Crystal, than for me!)  People have arable land and use it for lawn grass, and the greatest amount of that biomass is sent to landfills.  Even if it’s composted, it doesn’t compost well.  Inexcusable.  I’d suggest planting veggie gardens in one’s front lawn, but — and this shows what a sorry state we’re in, at least in SoCal — this would be frowned upon and make the homeowner embarrassed (if the homeowner cared what other people thought) or, perniciously, be illegal in some communities.

So if we grow a large chunk of our own food (literally) in our own backyards, buy most of the rest (figuratively) in our own backyards, and export (even for free) most of our corn, wheat, and soy to countries that literally cannot grow food, could we feed the whole world?  Yes.  Could we feed the whole world if all of this were organic?  I don’t know.  But I expect we could.
