Do not be naive. AIDS is not a curse from God to Africans or the black people. It is a tool to control them designed by some evil-minded scientists, but we may not know who particularly did it.

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

For me, one of the major reasons to move beyond just the planting of trees was that I have tendency to look at the causes of a problem. We often preoccupy ourselves with the symptoms, whereas if we went to the root cause of the problems, we would be able to overcome the problems once and for all.

It's the little things citizens do. That's what will make the difference. My little thing is planting trees.

We cannot tire or give up. We owe it to the present and future generations of all species to rise up and walk!

Nobody in the world is completely dependent on another person, but we are all interdependent.

As a scientist I cannot say we don't want to hear anything about GMOs, because these are advances in science. But I think its also important, especially when you are dealing with food, to be cautious.
