I'm swanning round the world looking at the most fabulously interesting things. Such good fortune.

I'm luckier than my grandfather, who didn't move more than five miles from the village in which he was born.

I don't know [why we're here]. People sometimes say to me, 'Why don't you admit that the humming bird, the butterfly, the Bird of Paradise are proof of the wonderful things produced by Creation?' And I always say, well, when you say that, you've also got to think of a little boy sitting on a river bank, like here, in West Africa, that's got a little worm, a living organism, in his eye and boring through the eyeball and is slowly turning him blind. The Creator God that you believe in, presumably, also made that little worm. Now I personally find that difficult to accommodate.

Its about cherishing the woodland at the bottom of your garden or the stream that runs through it. It affects every aspect of life.

This last chapter .. may have given the impression that somehow man is the ultimate triumph of evolution, that all these millions of years of development have had no purpose other than to put him on earth. There is no scientific evidence whatever to support such a view and no reason to suppose that our stay here will be any more permanent than that of the dinosaur.

How could I look my grandchildren in the eye and say I knew what was happening to the world and did nothing.

I think the most alarming animals I have encountered are really poisonous snakes.
