'In this book, written in crystal clear style, Herman Daly reiterates the main points of his analysis and vision, he praises some teachers (John Ruskin, Frederick Soddy, Nicholas Georgescu-Roegen, Kenneth Boulding), he fearlessly attacks some adversaries in the World Bank and MIT, and he offers some advice to the government of his own country, to the Russian Duma, and especially to OPEC that, if followed, would change the world very much for the better. Finally, on a different line of thought, he interrogates conservation biologists on their reasons for wanting to keep biodiversity since, as biologists, they claim that evolution has no particular purpose. Why not let the Sixth Great Extinction run its course? In other words, science cannot provide an ethics of conservation, which Herman Daly finds in religion more than in democratization deliberations.' - Joan Martinez-Alier, Universitat Autonòma de Barcelona, Spain
