This groundbreaking book explores the inherent interconnectedness of sustainability and spirituality, acknowledging the dependency of one upon the other. John E. Carroll contends that true ecological sustainability, in contrast to the cosmetic attempts at sustainability we see around us, questions our society's fundamental values and is so countercultural that it is resisted by anyone without a spiritual belief in something deeper than efficiency, technology, or economics. Carroll draws on the work of cultural historian and "geologian" Thomas Berry, whose eco-spiritual thought underlies many of the sustainability efforts of communities described in this book, including particular branches of Catholic religious orders and the loosely organized Sisters of the Earth. The writings of Native Americans on spirituality and ecology are also highlighted. These models for sustainability not only represent the tangible link between ecology and spirituality, but also, more importantly, a vision of what could be.
