Because you don't need energy, human or otherwise to ship food or material to where the people are. Because we stack functions through time and space. Because it solves the distribution problem. Because it's already working and all we need to do is expand. Because the sun's shines everywhere. Because polyculture allows for more variety and a single crop failure doesn't need to be insured. Because we could close loops naturally and avoid polluting, we would feed animals like chickens food scraps and compost locally in the gardens and forests. Because we can do better.
