We have so far to go to realize our human potential for compassion, altruism, and love.

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.

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.

Chimpanzees, gorillas, orangutan shave been living for hundreds of thousands of years in their forest,living fantastic lives, never overpopulating, never destroying the forest. I would say that they have been in a way more successful than us as far as being in harmony with the environment.

Without the support of local people, you might as well give up because you can make all the noise you like, you can demarcate a national park, but if the people outside want to go creeping into a forest you really can't stop them. They've got to get a benefit.

One individual cannot possible make a difference, alone. It is individual efforts, collectively, that makes a noticeable difference - all the difference in the world!
