In this innovative and deeply felt work, Bron Taylor examines the evolution of green religions in North America and beyond: spiritual practices that hold nature as sacred and have in many cases replaced traditional religions. Tracing a wide range of groupsradical environmental activists, lifestyle-focused bioregionalists, surfers, new-agers involved in ecopsychology, and groups that hold scientific narratives as sacredTaylor addresses a central theoretical question: How can environmentally oriented, spiritually motivated individuals and movements be understood as religious when many of them reject religious and supernatural worldviews? The dark of the title further expands this idea by emphasizing the depth of believers' passion and also suggesting a potential shadow side: besides uplifting and inspiring, such religion might mislead, deceive, or in some cases precipitate violence. This book provides a fascinating global tour of the green religious phenomenon, enabling readers to evaluate its worldwide emergence and to assess its role in a critically important religious revolution."
