Rewilding North America?!

Elephants might graze upon the Great Plains, stalked again by lions. Camels might wander parts of the American Southwest. And cheetahs might once again chase after pronghorn antelope. While I realize that monkeys might also fly out of my butt, I do so love the notion that we might one day be able to trade our global fear of imminent ecological collapse for the much more personal, rational, and managable fear of being eaten.
