The central message of this book is that religion has a special role to play in saving the planet. Religion has the unique power to fire the imagination and empower the will to break the cycle of addiction to nonrenewable energy. The environmental crisis is a crisis not of the head but of the heart. The problem is not that we do not know how to stop climate change but rather that we lack the inner strength to redirect our culture and economy toward a sustainable future. Only a bold and courageous faith can undergird a long-term commitment to change. This book is a call to hope, not despair – a survey of promising directions and a call for readers to discover meaning and purpose in their lives through a spiritually charged commitment to saving the Earth.
