Remember this isn't about getting lions out of zoos. I love zoos and I think a good zoo is great for society. What this is about is making sure that lions have a chance to thrive- to get them out of 'bad' zoos or parks and to make sure they don't end up victims of some kind of canned hunt. Keep in mind that canned hunting is one of the lowest things you can do to an animal and personally, I'm tired of hearing about a lot of nice animals falling victim to it.
