A foundational resource for readers investigating religiously motivated environmentalism, this book provides both a global overview of the subject and a detailed discussion of key figures, concepts, organizations, events, and documents.Beginning in the late 1960s, a growing number of activists, scholars, and scientists asserted that traditional religions had been major contributors to the environmental crisis. In response, theologians, religious organizations, and religiously motivated activists became increasingly involved in environmental issues. At the same time, emerging nature-based belief systems emphasized values and lifestyles based in environmentalism. More recently, religiously motivated environmentalism has become a powerful force in shaping environmental policy and human action globally and has joined with secular environmentalism to address related issues. This book explores the background and current state of religious environmentalism. The book begins with an overview essay examining the history and context of religious environmentalism and its significance today. A chronology then profiles the most important events related to religious environmentalism. A section of more than 50 alphabetically arranged reference entries follows, with each entry providing objective information about people, places, events, movements, works, and other topics. The entries include cross-references and suggestions for further reading, and the book closes with a selected, annotated bibliography of major works.
