Keeping the million dollar gorillas safe

Dr Gladys Kalema-Zikusoka is a wildlife vet who has made it her mission to prevent the spread of human disease to Uganda's precious and highly endangered mountain gorillas. Each gorilla group is worth a million dollars in tourism, and Gladys leads a charity that engages people living near their habitats in how to keep the gorillas safe from illness.
