This book, arising from over twenty years experience of working with the world's major faiths, draws extensively upon joint World Bank and ARC (Alliance of Religion and Conservation)/WWF (World Wildlife Fund for Nature) projects world wide. It shows, through stories, land management, myths, investment policies, legends, advocacy and celebration, the role the major faiths have, do and can play in making the world a better place. The major faiths are the oldest institutions in the world and have survived essentially because they are constantly evolving and changing. There is much to be learnt by newer institutions such as the World Bank and the multitudes of NGOs about how to remain true to what you believe but change and grow as you develop. The book explores issues of climate change, forestry, asset management, education and biodiversity protection and does so using the techniques of the great faiths storytelling, example and celebration. It reveals a variety of world views and it asks us to see that our personal view may be just one amongst many. The challenge of living with integrity in a pluralist world underlies the book and it offers models of how diversity is crucial in attempting to ensure we have a sustainable world.
