It would be absolutely useless for any of us to work to save wildlife without working to educate the next generation of conservationists.

A book came out recently written by scientists and environmentalists that made me so angry. It said the only thing we have to worry about is big industry. Each individual who tries to make his or her own environment better is useless. I find this criminal, because then you have a billion people all saying, It doesn't matter what I do because I'm just one person. But if you turn that around and a billion people say, What I do does make a difference, then it will make a difference.

In a very unscientific statement, I feel that there's been a disconnect between this clever brain and the heart.

Your life matters. You can't live through a day without making an impact on the world. And what's most important is to think about the impact of your actions on the world around you.

I cannot remember a time when I did not want to go to Africa to study animals.

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.

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.
