Zoo Outreach Organisation (ZOO), India started off as an NGO primarily focusing on training Zoo staff and bettering the circumstances of captive animals in Indian zoos. It has since evolved into an overall nature and wildlife conservation NGO, and is an affiliate member of the World Association of Zoos and Aquariums (WAZA).Zoo Outreach Organisation (ZOO) was so named because its initial activity involved primarily zoos, and its purpose was to "reach out" and involve more people with zoos.
