Book excerpt: The past few decades have seen the beginnings of a convergence between religions and ecological movements. The environmental crisis has called the religions of the world to respond by finding their voice within the larger Earth community. At the same time, a certain religiosity has started to emerge in some areas of secular ecological thinking. Beyond mere religious utilitarianism, rooted in an understanding of the deepest connections between human beings, their worldviews, and nature itself, this book tries to show how religious believers can look at the world through the eyes of faith and find a broader paradigm to sustain sustainability, proposing a model for transposing this paradigm into practice, so as to develop long-term sustainable solutions that can be tested against reality.
