Can capitalism be sustainable? Is it progress if a cannibal uses a fork? Elkington answers yes to both, showing how sustainable capitalism constitutes progress. The prongs of the fork -- economic prosperity, environmental quality, and social justice -- are laid forth in seven "great revolutions" of modern business. This is a superb and coherent argument for corporate sustainability. Elkington buttresses his vision through real-life examples of how companies are rising to the challenges, overcoming blind spots, and taking the lead. Highly recommended.
