Resources on the planet are limited, and limited resources can come to an end. But there are also a lot of resources that are renewable. A lot of land, for example, can be reclaimed from the encroaching deserts.

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.

After Hurricane Katrina, many people said that the levees were not as effective as the natural vegetation that had been removed at the coast.

We know that the US government is literally buying these lands back to allow them to be rehabilitated.

Some say that AIDS came from the monkeys, and I doubt that because we have been living with monkeys from time immemorial, others say it was a curse from God, but I say it cannot be that.

Obviously the world is moving away from high carbon energy to low carbon energy, and eventually moving away toward renewable energy. So it is in the interest of Africa to move towards that, because that's where the world is moving.

It is important to nurture any new ideas and initiatives which can make a difference for Africa.

All of us have a God in us, and that God is the spirit that unites all life, everything that is on this planet.
