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

I think I'd like to be remembered as someone who really helped people to have a little humility and realize that we are part of the animal kingdom not separated from it.

There isn't a sharp line dividing humans from the rest of the animal kingdom. All the time, we find animals doing things that, in our arrogance, we thought were just human.

Science demands objective factual evidence - proof; spiritual experience is subjective and leads to faith.

I want to change awareness.

As a child, we couldn't afford holidays overseas, so instead I travelled through books. I was inspired by Dr Dolittle and Tarzan.
