For what it's worth, most modern food animals and plants are still capable of producing natural offspring and sustaining life on their own. GMO presents some interesting challenges, but the main thing is that modern offshoots of wild organisms are bred to produce these outcomes, but they are bred, which means that they are within the range of variability of the population in question, even if they're out in the bell curve a bit. I think there's a significant qualitative difference between cheese, for example, of any variety, and "processed cheese" which is designed to mimic cheese properties but make it uniform over time and region by substituting simple chemicals (i.e., reductive by definition) for ingredients which came about by co-evolution in our ecosystems.
