Zookeeper turned TV star “Jungle Jack” Hanna, pictured, right, headlines the April 10 breakfast program of the Environmental Professionals Network at Ohio State. He’s director emeritus of the Columbus Zoo and Aquarium and host of the nationally syndicated Jack Hanna’s Into the Wild. He’ll talk about Earth Day and the new myActions.org social network, a campaign promoting sustainability. At last count, there were 20 free registrations left for Ohio State students (some 660 students have registered already!), and paid registration for members and non-members of the network also is available.
