It's like saying that two and two equals four, but if you wish to believe it, it could also be five ... Evolution is not a theory; it is a fact, every bit as much as the historical fact that William the Conqueror landed in 1066.

The savage, rocky shores of Christmas Island, 200 miles south of Java, in the Indian Ocean. It's November, the moon is in its third quarter, and the sun is just setting. In a few hours from now, on this very shore, a thousand million lives will be launched.

The most extraordinary thing about trying to piece together the missing links in the evolutionary story is that when you do find a missing link and put it in the story, you suddenly need all these other missing links to connect to the new discovery. The gaps and questions actually increase - it's extraordinary.

All we can hope for is that the thing is going to slowly and imperceptibly shift. All I can say is that 50 years ago there were no such thing as environmental policies.

The fundamental issue is the moral issue.

The only acceptable way to solve ecological problems is if you can persuade people to have fewer children. In the Victorian times, there were families of 15 children. Someone like Edward Lear, he was the last of 21 children. And so what we have to think about is offering people the alternative choice. And in the West, that's what's happening. The birth rate has been dropping steadily and still is. I'm wanting human beings to be better off so they don't view children as an insurance for the future.

To suggest that God specifically created a worm to torture small African children is blasphemy as far as I can see. The Archbishop of Canterbury doesn't believe that.
