I always loved animals. And when I was ten, I decided I had to go to Africa and live with animals and write books about them.

I wasn't trying to be a scientist. I only ever wanted to be a naturalist, like a David Attenborough.

If we do not do something to help these creatures, we make a mockery of the whole concept of justice.

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.

To reconnect with nature is key if we want to save the planet.

One thing I had learned from watching chimpanzees with their infants is that having a child should be fun.

My favorite animals are dogs.
