When you meet these outstanding leaders who have been through a programme that empowers them to take positive action, to make things better for people, for animals and for the environment - when you watch them interact and they start brainstorming, you realise you can relax, because they have got it right. They understand that there's more to this life than just money.

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.

Never be arrogant or abrasive. Treat your opponent respectfully if they really and truly believe they are right.

What makes us human, I think, is an ability to ask questions, a consequence of our sophisticated spoken language.

The more we learn of the true nature of non-human animals, especially those with complex brains and corresponding complex social behavior, the more ethical concerns are raised regarding their use in the service of man - whether this be in entertainment, as "pets," for food, in research laboratories, or any of the other uses to which we subject them.

We are always talking about how we can get more environmental and humanitarian education. It is about listening to the voice of young people - how they feel, and what would be most meaningful for them.

I believe sharing stories and experiences is the best way to teach people to empathize!
