History illustrates the power of religion to bring about change. Describing how world religions have begun to broaden their focus on God-human and human-human relationships to encompass human-Earth relations, the author calls for an alliance of religion and ecology against unlimited economic growth, rampant consumption, and unrestrained corporate globalization. In light of the environmental crisis, Tucker argues, religion must move from an isolated orthodoxy to inter-faith dialogue, and use its collective authority for liberation rather than oppression.
