Conclusion

His efforts in the Columbus Zoo made it a local institution but a model of habitat design, interaction, and conservation. He made animal worlds otherwise distant reach into common discourse, through television, books, and in the street.

Yet it is also through his story that we are made to remember that nothing comes easy to any legacy. With his struggles with his health and criticism of the animal trade as well as internal governance problems at the institutions, the story becomes more complex. The weakness of fronts is portrayed through the years of his Alzheimer diagnosis.

However, possibly the biggest out of all lessons is that even the greatest legacies are quantified not only in accomplishments, but also in inspirations left behind. Jack Hanna might not be able to travel or make any public speeches, but the flame he started, in the audience, among young naturalists, in conservation, goes on. The story of his life demonstrates how an individual with passion and heart can increase concern over animals and the planet. And more than that, it urges us to defend, challenge, and sustain those institutions and individuals who continue to do that work.
