I'm watching a show about reintroducing bison to the great plains, because man killed most of them off. In the same breath they talk about how indians would burn the plains to attact bison to the new growth and that's why there were so many of them. Who decides which is the natural order? I'm fairly sure that by increasing the number of bison, the indians caused the decrease of some other creature. If we are going to get the world back to how it was before man crashed the party and ruined everything what do we aim for? primordial soup?
