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.

An individual citizen cannot protect himself from the powers of large corporations or external governments. It is the responsibility of the government to protect its citizens.

When these resources are degraded or polluted, then there are fewer of them for the rest of us, and then we start competing for them and eventually as we compete, there are those of us, who have the capacity, who have the ability to be the controllers, to decide who accesses them, how much they access, and eventually there is a conflict. Those who feel marginalized, those who feel excluded, eventually react in an effort to get their own justice, and we have conflict.

I am working to make sure we don't only protect the environment, we also improve governance.

Using trees as a symbol of peace is in keeping with a widespread African tradition. For example, the elders of the Kikuyu carried a staff from the thigi tree that, when placed between two disputing sides, caused them to stop fighting and seek reconciliation. Many communities in Africa have these traditions.

We tend to put the environment last because we think the first thing we have to do is eliminate poverty. But you can't reduce poverty in a vacuum. You are doing it in an environment.

When you think of all the conflicts we have - whether those conflicts are local, whether they are regional or global - these conflicts are often over the management, the distribution of resources. If these resources are very valuable, if these resources are scarce, if these resources are degraded, there is going to be competition.
