When people refuse to see proof, they are think their belief helps them so, losing it will cost more then gaining it from a perhaps more truthfull story. I can tell you it is not, but one will never see that when in doubt.
And basicly, our choices of what to believe in life, make our life the way it is now. We are shaped by the beliefs we choose to carry.
The problems we have now in communities and societies are going to be resolved only when we are brought together by a common sense that each of us is a visionary. Each of us must come to the realization that we can function and live at the level of vision rather than following some great leader's vision. Instead of looking for a great leader, we are in an era where each of us needs to find the great leader in ourselves.
As long as Nature is seen as something outside ourselves; frontiered and foreign, separate, it is lost both to us and in us. It follows that to achieve a society in harmony with Nature, we must be guided by respect for it.
