So though a hunter-gatherer food chain still exists here and there to one degree or another, it seems to me its chief value for us at this point is not so much economic or practical as it is didactic. Like other important forms of play, it promises to teach us something about who we are beneath the crust of our civilized, practical, grown-up lives. Foraging for wild plants and animals is, after all, the way the human species has fed itself for 99 percent of its time on earth; this is precisely the food chain natural selection designed us for.
