I think [GMO] is one area where the is a need for legal regulations to make sure that companies - because at the moment, companies are the ones that have this technology - will not use this technology in a way that could adversely affect the people.

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.

The women of the Green Belt Movement have learned about the causes and the symptoms of environmental degradation. They have begun to appreciate that they, rather than their government, ought to be the custodians of the environment.

For me, one of the major reasons to move beyond just the planting of trees was that I have tendency to look at the causes of a problem. We often preoccupy ourselves with the symptoms, whereas if we went to the root cause of the problems, we would be able to overcome the problems once and for all.
