Legendary conservationists show us that we still have the power to prevent critical consequences of the sixth extinction in this game-changing book.

Can we save threatened animals and ecosystems in the midst of a mass extinction? The answer is a resounding yes! Before They Vanish shows us how. In this wise and impassioned book, renowned conservation scientists Paul R. Ehrlich, Gerardo Ceballos, and Rodolfo Dirzo urge us to shift our thinking rather than succumb to grief over the losses that humanity faces. This comprehensive look at a crucial but often overlooked aspect of conservation—population extinction, or the loss of a species within a specific geographic location—guides us onto a new, hopeful path.

The authors argue that conservationists have placed too much emphasis on the extinction of entire species, which occurs gradually enough that we only detect it in the direst of cases. By that time, meaningful action may be impossible. By shifting our focus to identifying extinction threats at the more localized population level, we can intervene more rapidly and effectively to prevent broader declines before it's too late. This change in perspective represents a critical step in saving these vanishing species; early detection and intervention may be our last, best hope for stemming the tide of this global crisis.

Using examples from the worlds of vertebrates, invertebrates, plants, fungi, and microorganisms, the authors explain the concept of population extinction, its causes and consequences, and how to prevent the mass destruction of the amazing and unique creatures with whom we share our planet. This call to action is a must-read for anyone concerned with saving endangered and threatened species, our natural world—and ourselves.

One of the most powerful and important books on the global environmental crises humanity faces.
—Independent Australia
A call to action....Civilisation depends on natural systems for the services they provide. Allowing them to disappear not only threatens civilisation itself but, as the authors insist, it is 'just plain morally wrong.'
—Sustainable Population Australia
Ehrlich and his colleagues present powerful evidence of global wildlife decline and more extinctions to come....Grief for what has been lost permeates the book. And the authors, whose careers have spanned a period of dramatic wildlife decline, use personal anecdotes and rich imagery to powerful effect.
