Although I understand that you are fighting for a cause that is beneficial for these animals, zoos and circuses have been traditional across the world for decades and even centuries. Traditions, yes, do change, but old habits die hard and I do not believe that this will be an easy task to accomplish. I am as much of an animal lover as the next, but I know that it will be easier for me to go to a zoo to see exotic animals than it would be for me to find a 'local' sanctuary or safari to go on.
