Join us as Smithsonian scientists highlight, Extinctopedia: Discover what we have lost, what is at risk, and how we can preserve the diversity of our fragile planet.

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—hopes for animals that 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.
