I don't want to go and start trying to make jokes in places like India, Tanzania or Iraq. Afghanistan is not a funny place.

Every atom you possess has almost certainly passed through several stars and been part of millions of organisms on its way to becoming you. We are each so atomically numberous and so vigorously recycled at death that a significant number of our atoms-up to a billion for each of us, it has been suggested-probably once belonged to Shakespeare. A billion more each came from Buddha and Genghis Khan and Beethoven, and any other historical figure you care to name.

At the foot of the mountain, the park ended and suddenly all was squalor again. I was once more struck by this strange compartmentalization that goes on in America -- a belief that no commercial activities must be allowed inside the park, but permitting unrestrained development outside, even though the landscape there may be just as outstanding. America has never quite grasped that you can live in a place without making it ugly, that beauty doesn't have to be confined behind fences, as if a national park were a sort of zoo for nature.

Britain still has the most reliably beautiful countryside of anywhere in the world. I would hate to be part of the generation that allowed that to be lost.

The whole of the global economy is based on supplying the cravings of two per cent of the world's population.

You don't have to know anything about baseball to respond to Babe Ruth because he's just this magnificent human being. And a really good story because he was this kid who grew up essentially as an orphan, you know, had a tough life, and then he became the most successful baseball player ever. But he was also a really good guy.

Science has been quite embattled. It's the most important thing there is. An arts graduate is not going to fix global warming. They may do other valuable things, but they are not going to fix the planet or cure cancer or get rid of malaria.
