I never know whether to label some of these images as pictures from space - or art. Here's one of the Caspian Sea and it would grace any art gallery. The Caspian Sea is the biggest landlocked body of water in the world. It's bigger than Germany. It's also suffering from a fair bit of pollution, judging from this picture. Algal blooms are created by excess nutrients in the water - often fertilizers.
