We may get to the point where the only way of saving the world will be for industrial civilization to collapse.

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.

I believe we are going to move into a situation where the more effective conferences will be smaller, more specialized, more focused, with occasional large gatherings to get the attention of the larger world.

I am President of the UN created University for Peace, which has a strong commitment to the relationship between peace, security and the environment. I meet with young people around the world and I always come away enthused and encouraged.

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

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?

I am convinced the prophets of doom have to be taken seriously.
