What is you where the last of your species on earth? Around the globe, unique and fascinating species face extinction from hunting and habitat destruction, which affects vulnerable animals in every kind of environment. Biologists, conservationists, wildlife preservation centers and zoological parks work to breed and shelter rare and critically endangered animals when and where they can, but many species are down to the last few individuals and face an increasingly uncertain future. For some, however, the future is all too clear. Lonesome George, a Pinta Island tortoise from the Galapagos Islands, is the very last of his kind. For centuries, until they were believed to be extinct, his species kept sailors and pirates well-fed on the high seas. George alone survived. Each species in trouble presents unique challenges, including inbreeding and lack of genetic diversity, sibling rivalry on an extreme scale, and individuals who may never have seen another of their kind. The Loneliest Animals follows the plight of these incredible, charismatic creatures and the struggles of the dedicated conservationists who fight for them.
