In moments of great grief, that's where you look and immerse yourself. You realise you are not immortal, you are not a god, you are part of the natur… - David Attenborough

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.

An eye from another world; a smell-detector, investigating the path ahead. We don't often see a snail that way, and that's because we've only recently had the tiny lenses and electronic cameras that we need to explore this miniature world. But when we meet its inhabitants face to face, we suddenly realise that their behaviour can be just as meaningful to us as the behaviour of many animals more our own size.

I'm not an animal lover if that means you think things are nice if you can pet them, but I am intoxicated by animals.
