I can't be the first person to blog about google earth. But I am spending hours at a time panning around the surface of the world, captivated by colours and patterns, and thinking about how much of it is natural (what is 'natural' anyway?) and how much is influenced by human behaviour.
So, in order to pretend that this is actually time well spent, I'm going to do a series of blog posts. I'm starting with the Aral Sea, which straddles the border between Kazakhstan and Uzbekistan.
