We think that diamonds are very important, gold is very important, all these minerals are very important. We call them precious minerals, but they are all forms of the soil. But that part of this mineral that is on top, like it is the skin of the earth, that is the most precious of the commons.

Having studied biology really helped me a lot because I quickly understand how biological systems work, and how they fail, and the tragedy of when they fail, because we are dealing with life systems, and when we hear that a species has become extinct, or is threatened, you realize that this could mean that this species will disappear from the face of the earth forever! So that understanding really gives you energy to do something to save it.

I think that for anybody who has worked in the civil society, government bureaucracy moves very very slowly.

It was easy to persecute me without people feeling ashamed. It was easy to vilify me and project me as a woman who was not following the tradition of a 'good African woman' and as a highly educated elitist who was trying to show innocent African women ways of doing things that were not acceptable to African men.

And so I'm saying that, yes, colonialism was terrible, and I describe it as a legacy of wars, but we ought to be moving away from that by now.

Sometimes I feel frustration at the bureaucracy for not moving fast enough to deliver in the way that I would prefer. But that is probably because I have worked for many years in the civil society, which tends to move much faster than government.

You cannot protect the environment unless you empower people, you inform them, and you help them understand that these resources are their own, that they must protect them.
