Of all the animals, I'm most hopeful for the mountain gorillas. They face poaching and loss of habitat, but they also have a lot of support. However, they are pursued by hunters and have been stricken by the Ebola virus. An outbreak between 2002 and 2004 in Gabon and Congo may have killed as many as 5,000 gorillas. Their populations are increasingly isolated, putting them in danger of being picked off by hunters, farmers and disease.
