People are dynamic. They change, and soon as there are enough of you, things change [for a whole society].

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.

Sometimes when I talk to little children I remind them of the fact that when I was growing up myself, I used to play with frog eggs and tadpoles and I used to walk in the field, I used to literally copy whatever my mother was doing on the land. And that may be the reason why I eventually developed the passion for green and for the Earth. So it is extremely important for adults and especially those who are in charge of cities to make sure that we do not lose touch with the land and with the environment. And especially our children.

It was easy for me to be ridiculed and for both men and women to perceive that maybe I'm a bit crazy because I'm educated in the West and I have lost some of my basic decency as an African woman.

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.

It would be good for us Africans to accept ourselves as we are and recapture some of the positive aspects of our culture.

Every person who has ever achieved anything has been knocked down many times. But all of them picked themselves up and kept going, and that is what I have always tried to do.
