We owe it to ourselves and to the next generation to conserve the environment so that we can bequeath our children a sustainable world that benefits all.

We need to promote development that does not destroy our environment.

It would be good for us Africans to accept ourselves as we are and recapture some of the positive aspects of our culture.

When you have the environment degraded, it is always so that we are going to fight over the few resources that are left.

I think what the Nobel committee is doing is going beyond war and looking at what humanity can do to prevent war. Sustainable management of our natural resources will promote peace.

If you want the future generations to live in peace, we must invest in the protection of the environment and we must train especially our young people so that they don't think, for example, the whole world is like Japan.
