If you interpreted inclusion of the Bronx Zoo as an endorsement of keeping elephants in zoos, than you are mistaken. The Bronx Zoo is one of the world's leading research institutions and has an extraordinary program that supports elephant welfare around the world.<quoted text>
And why are zoos more humane? They are still in captivity. They are still controlled.
Is your problem the abuse or the captivity?
As for zoos in general, many provide a safe environment for elephants so that they can help to educate people and create a culture of care for wild animals. Any training of the elephants is done so that they can be safely examined by veterinary and to encourage mental and physical activity and social interaction. Are zoos an ideal life for an elephant? Of course not. But it does provide an educational value for the public without forcing the elephants to performing for audiences in response to trainers commands and physical abuse.
The circus places elephants in an center ring and has them perform in ways that teach audiences nothing about the elephants habitat or their life in the wild. There is little educational value and these shows are designed to make profit for the circus, not to improve the lives of the elephants.
