ABSTRACT
We live in a vast, three-dimensional, interconnected web of energy flows and life forms. Years ago our world appeared to be the size of whatever culture we lived within and felt as if it were stable and unchangeable. Our world is now understood to be planetary in scale, to be changing very fast, and to be situated either at the threshold of a planetary disaster of unprecedented magnitude or at the beginning of a sustainable new era. Whatever the outcome, the new state of the world will not be like it is today.
