I just read your speech "Technology & the Other War." I'm still confused over your meaning of "natural" and "unnatural." You're saying that buildings and airplanes are just as natural as a bird's nest and a beaver cutting down a tree for a dam. Correct? Does this mean that pollution from airplanes is natural as well? It seems that the pollution that we're pouring into the world is making the world very uninhabitable very quickly. Is this natural? • Ishmael.org, the work & philosophy of Daniel Quinn
