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

Let us develop respect for all living things. Let us try to replace violence and intolerance with understanding and compassion. And love.

The person who has the most influence on me is my mother. Think of life as a flight where we fly higher and higher. If I were a bird that needs feathers to fly higher, I would regard my mother as my strongest feather.

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.

I thought my life was mapped out. Research, living in the forest, teaching and writing. But in '86 I went to a conference and realised the chimpanzees were disappearing. I had worldwide recognition and a gift of communication. I had to use them.

For those who have experienced the joy of being alone with nature there is really little need for me to say much more; for those who have not, no words of mine can ever describe the powerful, almost mystical knowledge of beauty and eternity that come, suddenly, and all unexpected.

Chimps are very quick to have a sudden fight or aggressive episode, but they're equally as good at reconciliation.
