Eloquent, practical and wise, this book by one of the world’s most important scientists—and two time Pulitzer Prize winner—should be read and studied by anyone concerned with the fate of the natural world. It "makes one thing clear ... we know what we do, and we have a choice" (The New York Times Book Review).

E.O. Wilson assesses the precarious state of our environment, examining the mass extinctions occurring in our time and the natural treasures we are about to lose forever. Yet, rather than eschewing doomsday prophesies, he spells out a specific plan to save our world while there is still time. His vision is a hopeful one, as economically sound as it is environmentally necessary.
