Under the new plan, called Pleistocene "re-wilding," close cousins and counterparts of the lost beasts, mostly from Africa, would be released into large, protected tracts of land and allowed to roam freely. Ideally, such actions would not only give parts of North America back an approximation of their long-ago megafauna diversity, they would also help save animals such as the African cheetah from extinction.
I heard about this on All Things Considered the other day. Wow ... just ... wow.
