I want to change awareness.

We, as humans, have actually developed a sense of social responsibility. We have gone beyond our basic instincts.

Here we are, arguably the most intelligent being that's ever walked planet Earth, with this extraordinary brain ... and yet we're destroying the only home we have.

There are many animal-welfare groups that sometimes seem to forget that human beings are animals too, that we need to include them in our sphere of compassion.

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

Other people have talked about chimpanzees being a window into the past, which I suppose is true, in a way.

I see that within each human being there are two extremes: there's the loving, the passionate, altruistic side that has evolved with us, and then there's the violent, brutal side that has evolved with us. The question for each individual is: which side is going to come out on top?
