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 knew that I was not doing anything wrong, and I knew in my mind I was doing the right thing. I knew that the people who were going against me were not going against me for a good purpose. I knew that they were trying to justify their corruption and misgovernance.

Obviously the world is moving away from high carbon energy to low carbon energy, and eventually moving away toward renewable energy. So it is in the interest of Africa to move towards that, because that's where the world is moving.

Education is a very empowering experience, so many people who went to school also managed to improve their quality of life much faster because they could get a job, they could get money. Once people see that you improve your life if you are educated, then education becomes a valuable tool and people want it.

No matter who or where we are, or what our capabilities, we are called to do the best we can.

I learned in America a long time ago, the three R's, the principle of three R's - reuse, reduce, recycle. And as I say those words, there are so many things individually we can do to reduce - we don't need to consume as much as we are consuming. Reduce. And by reusing, we can reuse a lot of things we just throw into the dumpsite. And reduce the production. The more we reuse, the more we can reduce.

Education, if it means anything, should not take people away from the land, but instill in them even more respect for it, because educated people are in a position to understand what is being lost. The future of the planet concerns all of us, and all of us should do what we can to protect it. As I told the foresters, and the women, you don't need a diploma to plant a tree.
