My contribution to these discussions seeks to expand the analytical horizon of the foregoing discussion of civil religion both chronologically and geographically, with special attention to the growing importance of what I call “dark green religion,” and the possibility that it might precipitate the emergence of a global, civil earth religion. Dark green religion, as I have constructed the term, involves the perception that nature is sacred and has intrinsic value, the belief that everything is interconnected and mutually dependent, and a deep feeling of belonging to nature. Often rooted in an evolutionary understanding that all life shares a common ancestor, dark green religion generally leads to a form of kinship ethics that entails ethical responsibilities to all living things.
