Granted, it's not like smart decisions have exactly ruled the show but doesn't it seem pretty ridiculous given the resources with farming and such that the Terminus group would choose cannibalism as their food source? Humans look to be getting more and more scarce. This seems like a pretty dumb way to survive.
Anyone who's ever grown a vegetable garden knows how much space and work would be involved to produce enough food to feed a couple of dozen people even one meal a day. Those little planter boxes they had scattered around were cosmetic, nothing more.
