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 that for anybody who has worked in the civil society, government bureaucracy moves very very slowly.

That's the way I do things when I want to celebrate, I always plant a tree.

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.

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

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.

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