But we're not humanity, we're just one culture - one culture out of hundreds of thousands that have lived their vision on this planet and sung their song. If it were humanity that needed changing, then we'd be out of luck. But it isn't humanity that needs changing, it's just...us.

The world doesn't belong to us, we belong to it. Always have, always will. We belong to the world. We belong to the community of life on this planet--it doesn't belong to us. We got confused about that, now it's time to set the record straight

The world is not in any sense in danger from itself. The world is in fact not in any danger at all. It is we who are in danger.

And in spite of all the mastery we've attained, we don't have enough mastery to stop devastating the world, or to repair the devastation we've already wrought.

The obvious can sometimes be illuminating when perceived in an unhabitual way.

I hope it will not be too long before the technologies that support our population explosion begin to be perceived as no less hazardous to the future of life on this planet than the endless production of radioactive wastes.
