When you meet chimps you meet individual personalities. When a baby chimp looks at you it's just like a human baby. We have a responsibility to them.

In Tanzania, the chimps are isolated in a very tiny patch of forest. I flew over it 13 years ago and realized that, basically, all the trees had gone, that people all around the park are struggling to survive. It became very clear that there was no way to protect the chimps while the people were in this dire circumstance.

Your life matters. You can't live through a day without making an impact on the world. And what's most important is to think about the impact of your actions on the world around you.

Be assured that our individual actions, collectively, make a huge difference.

When I look back over my life it's almost as if there was a plan laid out for me - from the little girl who was so passionate about animals who longed to go to Africa and whose family couldn't afford to put her through college. Everyone laughed at my dreams. I was supposed to be a secretary in Bournemouth.

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

Chimps act the way they feel unless they are afraid of reprisal if they do so. But that doesn't apply to humans.
