I was with Ted Turner when he came to see Kofi Annan - the Secretary-General of the UN - to announce his decision to put $1 billion to the service of UN projects and programs.

A shift is necessary toward lifestyles less geared to environmental damaging consumption patterns.

What pleases me most is that sustainable development is on almost everybody's agenda now.

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

The real goal of the Earth Charter is that it will in fact become like the Ten Commandments.

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?

The combination of population growth and the growth in consumption is a danger that we are not prepared for and something we will need global co-operation on.
