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 this work 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.
