Book excerpt: A call to consciousness that combines spirituality and ecology and offers hope for the future. As the world's population explodes, cultures and species are wiped out, and we have now reached the halfway point of our supplies of oil, humans the world over are confronting difficult choices about how to create a future which works. Thom Hartmann proposes that the ony lasting solution to the crises we face is to re-learn the lessons our ancient ancestors knew - lessons that allowed them to live sustainably for hundreds of thousands of years - but which we've forgotten. Hartmann shows how to find this new and yet ancient way of seeing the world and the life on and in it, allowing us to touch that place where the survival of humanity may be found.
