The emerging 'environmentalization' of our civilization and the need for vigorous action in the interest of the entire global community will inevitably have multiple political consequences.

The problem the world faces today is that only one-third of the world's population lives in decent circumstances, while half the population of the world lives on one or two dollars a day.
