Most Africans don't get to see these wild animals at all. Once they see and learn about them, they are much more likely to become involved in protecting the environment.

Chimps are brutal, and it is so deliberate. The males go out and get near the boundary of their territory. And they walk very silently trying hard not to make any noise. They will climb into a tree and stare out over hostile territory for hours. They are waiting for the right opportunity. And then they attack.

It made me feel particularly sickened to know that this kind of callous attitude toward animals is repeated again and again in laboratories around this country.

Certainly it's very often true that women tend to be a bit quieter and more prepared to sit there and let the animal tell you things.

I just have this absolute belief that humans are moving away from cruelty and destruction towards a time when we can truly live in harmony with nature. When we understand that there is a spiritual power around us from which we can draw strength. That is where I believe human destiny ultimately is taking us. I just hope we have time.

But let us not forget that human love and compassion are equally deeply rooted in our primate heritage, and in this sphere too our sensibilities are of a higher order of magnitude than those of chimpanzees.

Some people say, therefore, that violence and war are inevitable. I say rubbish: Our brains are fully capable of controlling instinctive behavior.
