That's the whole problem when any one reintroduces any animal to where it once was. The people doing the reintroduction want the it to succede so badly that they do not make any kind of future provisions for controling the new population. They figure that nature will take care of itself. Well, it certainly will. If left to "grow" freely they will either eventually starve themselves to death after they deplete their food resources or begin dying of disease or severe winter weather cause they are not healthy enough to endure it. While at the same time they will hurt the rest of the population of all the other species that share the same lands, predators and prey alike.

We need both the predators as well as the prey animals if we want to have a balanced system but because humans have taken much of the land that was once available for the animals we have the ultimate responsibility to keep their populations under control or the animals will suffer the consequences. I really don't understand why biologists and animal rights people can't seem to get this fact. They all need each other to maintain a healthy balance and we must make sure that it stays in ballance.
