Cheetahs and elephants roaming free in USA

LionsYesterday, we were speaking here about prehistoric big cats in places where they disappeared (e.g. Europe). Today, I want to point at a surprising proposal made by Josh Donlan.

Recognizing that many big cats were roaming in North America tens of thousands of years ago, he want to re-introduce lions, cheetahs, elephants and other large animals in North America. He admits that this could be a bit difficult and that there is no way to rebuild the original population. But he offers ideas about how to bring camels and lions (from the closest relatives species) to a country were they were last seen hundreds of centuries ago.

Of course, it sounds a lot like Jurassic Park for real. Are you ready to find in the United States cheetahs hunting pronghorn bucks in the Wild West (wild again) or in Montana?
