Shades of Jurassic Park

When I think of North America (NA), I sometimes thing of "home home on the range" and "deers and antelopes playing". Well, that may not exactly be the vision of scientists who are planning to reintroduce rather large mammals - elephants, lions and cheetahs - back into NA. As well as acting as breeding sanctuaries for animals under threat in Africa and Asia, the parks, set up over large tracts of NA, could be major tourist attractions. Again, shades of Jurassic Park - or Jumanji as the Yahoo report said. Yes, yes, we all know that most modern African species never lived on the American prairie, but the scientists have thought of that and they believe today's animals could duplicate the natural roles played by their departed, even larger cousins - mastodons, camels and saber-toothed cats! (I'm not sure which of the animals they're planning to transplant equates to camels)
