This begs several questions:

1. If they're worried about gaseous emissions from cattle, isn't this worse?

2. What will authorities do to keep their numbers in check? Hunting? State-sponsored culling? Will they be suggesting people eat them?

3. Who will control their ranges? If so, how? What happens should you wake in the night to find your garden being decimated by mammoths? Or they trample your car? People do live in the areas they are suggesting inserting these creatures.

4. Will they occasionally have to shoot them with tranquilizer darts to check up on their DNA progression from generation to generation? In other words, track them like they do other species like wolves or polar bears?

5. What happens if they migrate from one sovereign nation to another? Will that nation be welcoming to creatures that I'm sure eat massive amounts of flora.
