Apart from anything else, I am designed by evolution, like we all are: if we see a little thing like that, big eyes, tiny nose, we go 'aaah'. That's what evolution does. We are programmed to do that. So to find babies the most amazing, isn't surprising, I don't think.

You have to steer a course between not appalling people, but at the same time not misleading them.

Can a growing human population still leave space for wildlife?

The climate, the economic situation, rising birth rates; none of these things give me a lot of hope or reason to be optimistic.

I'm no longer sceptical. I no longer have any doubt at all. I think climate change is the major challenge facing the world.

I've never actually met one in the wild, but I have seen a king cobra. They go towards people, they rear up six feet tall and they're very aggressive and they are very fast. And one bite means certain death. So if I encountered a king cobra in the wild I would be very alarmed.

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.
