Those that live in the air have to fight in the air. - David Attenborough

Um, so, the world is not as wild as it was. Well, we've destroyed it. Not just ruined it. I mean, we have completely... well, destroyed that world. That non-human world is gone. Uh.... The... Human beings have overrun the world.

And this is where it went. In places all around the eastern Mediterranean the sea is separated from the mainland by strips of flat marshy land like this. Made up of the soil that once clothed the hills beyond. All this was deposited during the last 2000 years. This is the marsh that now separates the sea from the city of Ephesus. These ruined buildings mark the edge of the quay where once merchant ships lay moored. As the harbour died, so did the trade upon which the city's wealth was based, and so, well, ultimately did Ephesus itself. What was once one of the most splendid cities in the Roman Empire fell into decay and was abandoned.

I don't know [why we're here]. People sometimes say to me, "Why don't you admit that the hummingbird, the butterfly, and 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 riverbank, like here, in West Africa, that's got a little worm, a living organism, that's in its eye and boring through its eyeballs and is slowly turning it blind. The creator God that you believe in, presumably, also made that little worm." Now I personally find that difficult to accommodate and so therefore [sic] when I make these films, I prefer to show what I know to be the facts, what I know to be true, and then people can deduce what they will from that.
