Ghost Bears [EPUB ebook] 
Exploring The Biodiversity Crisis

In Ghost Bears, R. Edward Grumbine looks at the implications of the widespread loss of biological diversity, and explains why our species-centered approach to environmental protection will ultimately fail. Using the fate of the endangered grizzly bear — the "ghost bear" — to explore the causes and effects of species loss and habitat destruction, Grumbine presents a clear and inviting introduction to the biodiversity crisis and to the new science of conservation biology.
