I think feeding the population now has become a form of population control anyhow. Did you see the latest French study on GMO? Irradiated and pesticide laden food takes its toll not only humans but animals and bees (colony collapse disorder) too. I'd suggest moving to biodynamic farming methods gradually. Such food is more nutritious anyhow. For your interest, I can stop my appetite dead in its tracks with a zinc supplement, (that's soil depletion for you.)
