If we allow the destruction of the environment, we can see the terrorists have utterly won, and are destroying the future of our children and grandchildren. We must not let that happen.

We could change the world tomorrow if all the millions of people around the world acted the way they believe.

I sometimes wonder how some people can live with themselves in some of the big companies today. So many far-reaching decisions are based on how they will affect the next shareholders' meeting.

And I thought how sad it was that, for all our sophisticated intellect, for all our noble aspirations, our aggressive behavior was not just similar in many ways to that of the chimpanzees - it was even worse. Worse because human beings have the potential to rise above their baser instincts, whereas chimpanzees probably do not.

It was both fascinating and appalling to learn that chimpanzees were capable of hostile and territorial behavior that was not unlike certain forms of primitive human warfare.

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

Every individual matters and has a role to play in this life on Earth.
