It is my firm belief that the infinite and uncontrollable fury of nuclear weapons should never be held in the hands of any mere mortal ever again, for any reason.

We need a new system of values, a system of the organic unity between humankind and nature and the ethic of global responsibility.

We must speak more clearly about sexuality, contraception, about abortion, about values that control population, because the ecological crisis, in short, is the population crisis. Cut the population by 90% and there aren't enough people left to do a great deal of ecological damage.

More socialism means more democracy, openness and collectivism in everyday life.

I remember Secretary of State [George] Shultz one day saying that America is an economic model for the world. I replied to him that America represents 5 percent of the world's population and consumes 30 percent of the world's energy. What if everyone in the world lives like Americans? Where do we get the energy for this standard of living?

We desperately need to recognise that we are the guests, not the masters, of nature and adopt a new paradigm for development, based on the costs and benefits to all people, and bound by the limits of nature herself rather than the limits of technology and consumerism.

A New World Order is required to deal with the Climate Change crisis.
