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.

The tree I had in the garden as a child, my beech tree, I used to climb up there and spend hours. I took my homework up there, my books, I went up there if I was sad, and it just felt very good to be up there among the green leaves and the birds and the sky.

As human beings, we can encompass a vague feeling of what the universe is, and all in this funny little brain here - so there has to be something more than just brain, it has to be something to do with spirit as well.

At some point, my body will collapse. But I hope that my brain will still be working so that I can carry on with writing.

My mission is to create a world where we can live in harmony with nature.

The chimpanzees taught me a lot about nonverbal communication. The big difference between them and us is that they don't have spoken language. Everything else is almost the same: Kissing, embracing, swaggering, shaking the fist.
