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.

When I went back home, I was constantly being reminded, I'm an African woman, and so there are certain things I shouldn't do, certain ambitions that I should not entertain. That was a problem for me because I had never thought of myself as an African woman, never thought of myself as a woman to begin with. For me the limit was my capacity, my capability.

I want to do the right things - I want to plant trees, I want to make sure that the indigenous forests are protected because I know, whatever happens, these are the forests that contain biodiversity, these are the forests that help us retain water when it rains and keep our rivers flowing, these are the forests that many future generations will need.

Until you dig a hole, you plant a tree, you water it and make it survive, you haven't done a thing. You are just talking.

One of the reasons why I've written The Challenge for Africa is to save it. Surely there are so many problems we can solve in Africa, but first and foremost, we need a government that feels responsible to protect their own people from the exploitations, from the misuse, from the mistreatment that they can easily get.

All of us have a God in us, and that God is the spirit that unites all life, everything that is on this planet. It must be this voice that is telling me to do something, and I am sure it's the same voice that is speaking to everybody on this planet - at least everybody who seems to be concerned about the fate of the world, the fate of this planet.

Because I was a woman, I was vulnerable. It was easy to vilify me and project me as a woman who was not following the tradition of a 'good African woman.'
