"The world's greatest naturalist" (Jeffrey Sachs) proposes a plan to save Earth's imperiled biosphere.

History is not a prerogative of the human species, Edward O. Wilson declares in Half-Earth. Demonstrating that we blindly ignore the histories of millions of other species, Wilson warns us that a point of no return is imminent. Refusing to believe that our extinction is predetermined, Wilson has written Half-Earth as a cri de coeur, proposing that the only solution to our impending "Sixth Extinction" is to increase the area of natural reserves to half the surface of the earth. Half-Earth is a resounding conclusion to the best-selling trilogy begun by the "splendid" (Financial Times) The Social Conquest of Earth (ISBN 978 0 87140 363 6) and "engaging and highly readable" (Times Higher Education) The Meaning of Human Existence (ISBN 978 0 87140 100 7).
