One of the reasons why we started the Green Belt Movement is to work with these ordinary peasant farmers so as to educate them that, despite the fact that they are poor, it is in their interest to protect the soil that they have, to protect the forest they have, to protect the land that they have, because if they don't do it, things can be only worse tomorrow for them for them and for their children.

I stand before you and the world humbled by this recognition and uplifted by the honour of being the 2004 Nobel Peace Laureate. As the first African woman to receive this prize, I accept it on behalf of the people of Kenya and Africa, and indeed the world. I am especially mindful of women and the girl child. I hope it will encourage them to raise their voices and take more space for leadership.

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.

And so I'm saying that, yes, colonialism was terrible, and I describe it as a legacy of wars, but we ought to be moving away from that by now.

Nobody in the world is completely dependent on another person, but we are all interdependent.

I have seen a lot of men, for example, who will make a will and include their daughters whether they are married or not. And perhaps the greatest change of attitude is that today, at least in Kenya, if you don't send your child to school - unless it's a matter of poverty or religion, and it is not that there no schools - then people wonder, "why the hell don't you send your children to school?" Now that's a very big jump from when I was going to school and educating girls was an exception to the rule.

We think that diamonds are very important, gold is very important, all these minerals are very important. We call them precious minerals, but they are all forms of the soil. But that part of this mineral that is on top, like it is the skin of the earth, that is the most precious of the commons.
