A Smithsonian collaboration–this journey of discovery through the animal kingdom, past and present, calls on us to educate ourselves and take action to save the amazing diversity of our planet. 
Every living creature contributes towards the richness and beauty of our planet. Each one has a reason to exist, from the giant panda to the pygmy possum, and if we lose them, it will be forever. Extinctopedia tells a complex story, not just of those who are extinct, but also of those in greatest peril, with explanations of what threatens their survival. It is also a story of hope – hope for animals who have been rediscovered, hope in the form of newly-discovered animals, and hope that we might hear the warning call and act to preserve the amazing biodiversity of our fragile planet for future generations to come.
