answer:I think it happens to be true, particularly based on my 5 years studying anthropology in college. It’s kind of what I’ve based a lot of my work on, and my experiences learning to be a hunter-gatherer-gardener have reaffirmed what the research says. Plus, you say we can’t go back to being hunter-gatherers because there are too many of us…but hunting, gathering, and gardening are the only sustainable way to produce food, and produce more per acre than monocrop agriculture. Monocropping’s only “advantage” is the ability of tyrants and autocrats to consolidate power. It doesn’t feed people adequately, and it doesn’t keep us healthy. The best chance we have is to learn how to apply these ways of subsistence to our landbases once again, particularly implementing methods like permaculture to build soil back up and feed us while reinforcing biodiversity.
