Only by understanding the Universe as a vast, holistic system and Earth as a unit within it can we help restore balance to that unit. Only by placing Earth and its ecosystems - about which we now understand so much - at the centre of all our thinking can we avert ecological disaster. Only by bringing our thinking back into balance with feeling, intuition and awareness, and by grounding ourselves in a sense of the sacred in all things can we achieve a new level of consciousness. Green spirituality is the key to a new, twenty-first century consciousness. And this book is the most comprehensive ever written on green spirituality.
