Faiths in Green addresses the complex and fraught relationship between religious identity and environmental concern in the United States, particularly how that relationship has changed over time. Examining the effects of religious upbringing, belonging, and disaffiliation on environmental concern across multiple religious groups over several decades, the author shows where, when, how, and why religious groups and their memberships have responded constructively to environmental change over time. The author also visits the effects of gender, social class, race, and politics on both religion and environmental concern in the U.S. Faiths in Green offers an in-depth and accessible guide to understanding the at-times incongruous relationship between religious beliefs and motivations, as well as ways to follow cultural shifts that both drive and are driven by religious persons and institutions. In examining how religious and cultural factors are linked to environmental concern over time, Faiths in Green demonstrates the importance of morality and worldviews in confronting global hazards of unprecedented scale.
