I think [GMO] is one area where the is a need for legal regulations to make sure that companies - because at the moment, companies are the ones that have this technology - will not use this technology in a way that could adversely affect the people.

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.

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.

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.

As long as we have all these conflicts, it is the women who will continue to suffer, so that is one reason why I guess as women we should really work for peace, because we know how painful wars can be to us and our daughters.

In Kenya, one of our biggest exports is coffee. Where do you grow coffee? You grow coffee in the land. To be able to grow coffee you need rain, you need special kinds of soils that are found on hillsides, and that means you have to protect that land from soil erosion so you don't lose the soil. You also want to make sure that when the rains come you're going to be able to hold that water and have it go into the ground so that the streams and the rivers keep flowing and the ground is relatively humid for these plants.
