Chimps are unbelievably like us - in biological, non-verbal ways. They can be loving and compassionate and yet they have a dark side... 98 per cent of our DNA is the same. The difference is that we have developed language - we can teach about things that aren't there, plan for the future, discuss, share ideas

One individual cannot possible make a difference, alone. It is individual efforts, collectively, that makes a noticeable difference - all the difference in the world!

I had this wonderful, supportive mother who didn't get mad because of all the earth mucking up my bed. She just said they'd die - they needed the earth.

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.

every individual can make a difference ... if we continue to leave decision making to the so-called decision makers, things will never change.

Chimpanzees, more than any other living creature, have helped us to understand that there is no sharp line between humans and the rest of the animal kingdom. It's a very blurry line, and it's getting more blurry all the time.

I was even accused of teaching the chimps how to fish for termites which I mean that would have been such a brilliant coup.
