We are unique. Chimpanzees are unique. Dogs are unique. But we humans are just not as different as we used to think.

Every individual matters. Every individual has a role to play. Every individual makes a difference.

If we kill off the wild, then we are killing a part of our souls.

Louis [Leakey] was anxious to initiate a scientific study of these chimpanzees. It would be difficult, he emphasized, for nothing was known; there were no guidelines for such a field study; and the habitat was remote and rugged. Dangerous wild animals would be living there, and chimpanzees themselves were considered at least four times stronger than humans. I remember wondering what kind of scientist he would find for such a herculean task.

The greatest danger to our future is apathy.

You cannot share your life with a dog, as I had done in Bournemouth, or a cat, and not know perfectly well that animals have personalities and minds and feelings.

Terrorism is fueled by hate. The tragedy is that there are countless young children who are being taught to hate. Terrorism is usually fueled also by poverty.
