The scarcest resource is not oil, metals, clean air, capital, labour, or technology. It is our willingness to listen to each other and learn from each other and to seek the truth rather than seek to be right
Donella MeadowsAny system, biological, economic, or social, that gets so encrusted that it cannot self-evolve, a system that systematically scorns experimentation and wipes out the raw material of innovation, is doomed over the long term on this highly variable planet.
Donella MeadowsI call the transformed world toward which we can move โsustainable,โ by which I mean a great deal more than a world that merely sustains itself unchanged. I mean a world that evolves, as life on earth has evolved for three billion years, toward ever greater diversity, elegance, beauty, self-awareness, interrelationship, and spiritual realization.
