We begin 2019 by celebrating an increasingly scarce conservation "win" with news by the IUCN that mountain gorillas have been down-listed from critically endangered to endangered. Mountain gorillas are the elusive great ape species introduced to most of the world by the famous primatologist Dian Fossey, who studied and ultimately lost her life protecting the animals. And who better to discuss the decades-long effort to preserve these gentle giants, not just for today but indefinitely, and to help the people of Rwanda than the director emeritus of the Columbus Zoo, Jack Hanna.    https://globalimpact.columbuszoo.org/projects/project/gorilla-doctors-in-africa www.peppermintnarwhal.com www.iReinforce.com https://www.iucnredlist.org/species/39999/17989719
