I don't care two hoots about civilization. I want to wander in the wild.

I got to Africa. I got the opportunity to go and learn, not about any animal, but chimpanzees. I was living in my dream world, the forest in Gombe National Park in Tanzania. It was Tanganyika when I began.

Even in chimps there is true altruistic behaviour; behaviour that doesn't fit into the sociobiological model that says you either help a close relative and thereby your own genes, or you help somebody else now in return for their help in the future. When a very high-ranking male chimpanzee rescues a little orphan, saving his life, that kind of explanation doesn't work.

Nothing is more precious than your baby.

There is a lot of corruption all over the world and not only when it comes to illegal wildlife trade! There are a few ways to ensure this stops: If there are no customers, there will be no trade.

We have a responsibility toward the other life-forms of our planet whose continued existence is threatened by the thoughtless behavior of our own human species. . . . Environmental responsibility – for if there is no God, then, obviously, it is up to us to put things right.

You have to realise that touching is a real violation of personal space.
