Occupy World Street is a masterpiece which deserves to get wide circulation and commitment by world leaders.

What if a small group of world leaders were to conclude that the principal risk to the Earth comes from the actions of the rich countries?... In order to save the planet, the group decides: Isn't the only hope for the planet that the industrialized civilizations collapse? Isn't it our responsibility to bring that about?

We owe at least this much to future generations, from whom we have borrowed a fragile planet called Earth.

I've developed a huge regard for Toyota for its environmental awareness, for its immense commitment to research and development in this field, and for its leadership in developing hybrids which others are now following.

We need what I have often called an ecological approach to the management of these resources and we do not have that now. We have the inertia of past habits, unsustainable habits.

We're either going to save the world or no one will be saved.

I've got used to criticisms and, naturally, I try to make sure I don't listen to the more extreme ones because most of the people who have taken their rightwing extremist view of my life are people that I've never met.
