"Off the land," Ellen Mae said, nodding. "It ain’t easy, that’s for sure. The old species balance, the original ecology, is completely shot out here. Believe me, it’s nothing like the High Plains used to be, and it never will be again. There’s all these foreign weeds, invader species, depleted soils, and the climate’s crazy. But the West Texas flora was always pretty well adapted to severe weather. So there’s still Comanche food around. Stuff like pigweed. Hell, pigweed’s an amaranth, it’s a really nutritious grain, but it’ll grow in a crack in a sidewalk. Of course, you’d never think to eat pigweed if you didn’t already know what it was."
