The hardest part of returning to a truly healthy environment may be changing the current totally unsustainable heavy-meat-eating culture of increasing numbers of people around the world. But we must try. We must make a start, one by one.

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 are unique. Chimpanzees are unique. Dogs are unique. But we humans are just not as different as we used to think.

Animals are as deserving of a place on this planet as we are, and the difference between us is that humans have a voice they can use to help the animal cause, and it is up to all of us to use it to make a positive difference!

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

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

It's the bond between mother and child, which is really for us and for chimps and other primates, the root of all the expressions of social behavior.
