In his 2010 book, "Dark Green Religion", Bron Taylor examines non-institutionalized forms of environmental spiritualities, which he categorizes as "religion" due to their attribution of intrinsic sacred value to nature or the earth. Taylor offers a structured framework for analyzing biocentric or ecocentric spiritualities, distinct from the religious traditions that originated in the Axial Age. Understanding them as a response to Charles Darwin's treatise, On the Origin of Species (1859), Taylor compiles a variety of phenomena, such as surfing spirituality and artistic expressions. These examples express a longing for new, meaningful relationships with non-human reality, countering the modern disenchantment of the world caused by the extensive impacts of industrialization and technologization. Taylor highlights the ecological relevance of these movements, while indicating the possible "shady" sides like intrinsic potentials of violence. This contribution presents Taylor's concept and the associated research, subjecting them to a critical discussion of their philosophical suppositions, and asks, from a Christian theological point of view, for potential trans-religious alliances in regard of the "care for our common home" (Laudato Si').
