Jack Hanna – 74 Years Old

Jack Hanna is an avid animal lover and a retired zookeeper. During his time at the Columbus Zoo, he worked hard to spread awareness about the injustice that the zookeeping business does to wildlife creatures by providing them tiny cages instead of natural habitats. Hanna’s activism made the kind man famous among people, and to increase his reach, Jack accepted the invitation to appear on TV shows like Good Morning America. It brought national attention to both – the zoo and Jack himself. His hard work paid off since he could provide a suitable environment to the animals while serving as the director from 1992 to 2020.
