Food is rapidly becoming more expensive. Like, even for spoiled Americans. Becoming unspoiled could be unpleasant. Or it could just mean more fresh local wild chaos food.
I heard about a greenhouse operation in Milwaukee, Wisc., where they lay down a lot of active wormy compost, lay down some finished compost on top, and plant in that. The active compost underneath helps warm everything. Big piles of compost in the corners also warm it up. Worms everywhere. No other power or heat source.
