Do not be naive. AIDS is not a curse from God to Africans or the black people. It is a tool to control them designed by some evil-minded scientists, but we may not know who particularly did it.

The issue of climate change, it really does bring home the fact that we are on one planet, and that some of the impact of what human beings do in one corner of the world is going to affect people in a distant corner of the world. So we may still feel very far from each other, but we are really very close to each other because of the changes we have made with travel and technology and especially the information technology.

We tend to put the environment last because we think the first thing we have to do is eliminate poverty and send children to school and provide health.

I have always felt that perhaps women have sometimes almost embraced the same values as men, and the same character as men, because they are in the men's world, and they are trying to fit into a system that men have created. And maybe in truth when there is a critical mass of women who play that role in governments, then we will see whether women can really manage power in a way that is less destructive than the way that men have used power.

We tend to put the environment last because we think the first thing we have to do is eliminate poverty. But you can't reduce poverty in a vacuum. You are doing it in an environment.

When you think of all the conflicts we have - whether those conflicts are local, whether they are regional or global - these conflicts are often over the management, the distribution of resources. If these resources are very valuable, if these resources are scarce, if these resources are degraded, there is going to be competition.

What people see as fearlessness is really persistence. Because I am focused on the solution, I don't see the danger.
