If a chimp who has been abused horribly by humans can help a human friend in a time of need, how much more should we help the animals - and other people for that matter - in their time of need?

The problem of the chimps is that they can only sit and look. They can't discuss what they feel. All that feeling is trapped within each one.

Become as knowledgeable as possible.

We're the ones who can make a difference. If we lead lives where we consciously leave the lightest possible ecological footprints, if we buy the things that are ethical for us to buy and don't buy the things that are not, we can change the world overnight.

The chimpanzees taught me a lot about nonverbal communication. The big difference between them and us is that they don't have spoken language. Everything else is almost the same: Kissing, embracing, swaggering, shaking the fist.

Anyone who tries to improve the lives of animals invariably comes in for criticism from those who believe such efforts are misplaced in a world of suffering humanity.

The best relationship you can have with a chimpanzee is total mutual trust.
