Here we are, the most clever species ever to have lived. So how is it we can destroy the only planet we have?

I always loved animals. And when I was ten, I decided I had to go to Africa and live with animals and write books about them.

Become as knowledgeable as possible.

Chimpanzees are incredibly intelligent. They can learn more than 400 signs of American Sign Language. They have memories for spatial distribution, like numbers on a TV screen, way better than ours. You come onto the emotions: happiness, sadness, fear, and despair - all the things for which I was accused of being anthropomorphic when I ascribed them to chimpanzees.

I have never had an animal that didn't have a personality, one differing from another.

We can learn to suppress our feelings for other reasons.

Every individual can make a difference every day by making conscious choices.
