Down to Earth scientifically describes the multitude of environmental problems besetting planet earth and indicates why these environmental problems are, at their root, a spiritual or religious challenge. Simply learning about the scientific description of these environmental threats will not be sufficient to solve them, the author argues, for attitudes must be changed and behavioral patterns must be altered. This need for change invariably confronts the core values that we hold and the routine actions that we undertake. Through an examination of the worldviews and sacred texts of eight spiritual traditions, we learn of the common insights and powerful resources that these world religions can offer. The author believes that it is necessary to join an ecological conscience to an ecological consciousness for humans to exercise custodianship of nature both responsibly and sustainably.
