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.

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.

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.

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 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.

The developed world should be willing to help [Africa] and support her and make this energy affordable.

It is very important for young people not to be afraid of engaging in areas that are not common to the youth. Get involved in local activities, get involved in local initiatives, be involved in leadership positions because you can’t learn unless you are involved. And if you make mistakes that is alright too because we all make mistakes and we learn from those mistakes. You gain confidence from learning, failing and rising again.
