We find animals doing things that we, in our arrogance, used to think was "just human".

You cannot share your life with a dog, as I had done in Bournemouth, or a cat, and not know perfectly well that animals have personalities and minds and feelings.

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

Chimps are brutal, and it is so deliberate. The males go out and get near the boundary of their territory. And they walk very silently trying hard not to make any noise. They will climb into a tree and stare out over hostile territory for hours. They are waiting for the right opportunity. And then they attack.

Every single day, we could be in a motorcar accident, so, we have to carry on with our lives, and not imagine terror around every corner.

We seem to have lost the wisdom of the indigenous people, which dictated that in any major decision, the first consideration was 'How will this decision we're making today affect our people in the future? These days, decisions are made based on the bottom line.

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.
