Christianity and the Environment. 'God is Green' examines what the Bible has to say about humanity's relationship with and responsiblity for the environment, and how Church traditions over the centuries have interpreted this. He argues that Christianity at its essence is a 'green faith' which has been distorted over the years. First published in 1990, this new edition of the book is revised for the contemporary state of our climate, and includes a chapter-by-chapter study guide for individuals and small groups.
