Brown (environment, McGill U.) and Garver, a Montreal-based law consultant and lecturer, offer people from all walks of life an ethical guidance system based on right relation in order to address the conflict between how people provide for themselves and the integrity of Earth's ecological and social systems. They meld scientific understanding, an ethical stance, and spiritual optimism to discuss such matters as a flourishing commonwealth of life, boundaries on consumption and waste, sharing, and new ways to play fair.
