My family has very strong women. My mother never laughed at my dream of Africa, even though everyone else did because we didn't have any money, because Africa was the 'dark continent', and because I was a girl.

Every individual can make a difference every day by making conscious choices.

I believe that the tragedy [like terror attack] that's caused so much grief and suffering to so many thousands and thousands of people has also served as a call to action, because many people now are re-examining their own value systems, and the churches, temples, mosques and cathedrals are packed to overflowing for the first time in years.

I see that within each human being there are two extremes: there's the loving, the passionate, altruistic side that has evolved with us, and then there's the violent, brutal side that has evolved with us. The question for each individual is: which side is going to come out on top?

A good mother is protective but not over-protective. She's patient, she's affectionate, she's playful, but above all she is supportive.

If we allow the destruction of the environment, we can see the terrorists have utterly won, and are destroying the future of our children and grandchildren. We must not let that happen.

I do not want to discuss evolution in such depth, however, only touch on it from my own perspective: from the moment when I stood on the Serengeti plains holding the fossilized bones of ancient creatures in my hands to the moment when, staring into the eyes of a chimpanzee, I saw a thinking, reasoning personality looking back. You may not believe in evolution, and that is all right. How we humans came to be the way we are is far less important than how we should act now to get out of the mess we have made for ourselves.
