The only possible way to get somebody to change is to reach into their hearts.

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

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

It was both fascinating and appalling to learn that chimpanzees were capable of hostile and territorial behavior that was not unlike certain forms of primitive human warfare.

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.

If you consciously say 'I won't do it!' to yourself, then you have a good chance that you won't.

I love to write - it is a great source of reflection, especially as I continue to meet many new inspiring people.
