" It has happened that a species has tried to live in violation of the Law of Limited Competition. Or rather it has happened one time, in one human culture—ours. That’s what our agricultural revolution is all about. That’s the whole point of totalitarian agriculture: We hunt our competitors down, we destroy their food, and we deny them access to food. That’s what makes it totalitarian. "

― Daniel Quinn , The Story of B (Ishmael, #2)
