I’m very conscious of the fact that you can’t do it alone. It’s teamwork. When you do it alone you run the risk that when you are no longer there nobody else will do it.

It is wonderful when you don't have the fear, and a lot of the time I don't ... I focus on what needs to be done instead.

It is evident that many wars are fought over resources which are now becoming increasingly scarce. If we conserved our resources better, fighting over them would not occur ... protecting the global environment is directly related to securing peace. Those of us who understand the complex concept of the environment have the burden to act. We must not tire, we must not give up, we must persist.

Why has there been so much secrecy about AIDS? When you ask where did the virus come from, it raises a lot of flags. That makes me suspicious.

We can work together for a better world with men and women of goodwill, those who radiate the intrinsic goodness of humankind. To do so effectively, the world needs a global ethic with values which give meaning to life experiences and, more than religious institutions and dogmas, sustain the non-material dimension of humanity. Mankind's universal values of love, compassion, solidarity, caring and tolerance should form the basis for this global ethic which should permeate culture, politics, trade, religion and philosophy. It should also permeate the extended family of the United Nations.

Unfortunately, the issues of climate change, unlike many other issues, are very subtle because the changes we observe are very, very subtle.

I think what the Nobel committee is doing is going beyond war and looking at what humanity can do to prevent war. Sustainable management of our natural resources will promote peace.
