Those of us who have been privileged to receive education, skills, and experiences and even power must be role models for the next generation of leadership.

Using trees as a symbol of peace is in keeping with a widespread African tradition. For example, the elders of the Kikuyu carried a staff from the thigi tree that, when placed between two disputing sides, caused them to stop fighting and seek reconciliation. Many communities in Africa have these traditions.

We do the right thing not to please people but because it's the only logically reasonable thing to do, as long as we are being honest with ourselves - even if we are the only ones.

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.

You cannot blame the mismanagement of the economy or the fact that we have not invested adequately in education in order to give our people the knowledge, the skills and the technology that they need in order to be able to use the resources that Africa has to gain wealth

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.
