Why do we have to have people come from afar to come and grow food for us, or to grow food to sell to us? It is partly because we are almost becoming used to people doing things for us. Like somebody else is going to solve that problem for us. And that to me is very disempowering system.

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.

We owe it to ourselves and to the next generation to conserve the environment so that we can bequeath our children a sustainable world that benefits all.

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.

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 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.

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
