Tiny bubbles

Wow, here is quite a visual:

The blue bubble on the left represents the volume of all of the world's water--oceans, lakes, rivers, and so on. And the pink bubble on the right is the Earth's atmosphere.

Standing on the beach and staring at the sea--or looking down from a airplane at cruising altitude--it's easy to forget how thin the livable skin our planet is.

The image is the work of Adam Nieman. More on him and his work in this New York Times piece.
