Outstanding paleontologist/environmentalist Flannery (Now or Never)-Australian of the Year in 2007 (I love that)-here elucidates two ways of viewing Earth's fate. The Medea hypothesis argues that, left untrammeled, species will exploit their ecosystems to the point of collapse. But James Lovelock's Gaia hypothesis counters that Earth knows how to adjust. Flannery favors the latter view, urging us to bond better with self-regulating nature. Good green reading.
