Great Photo showing how much water there is on earth relative to the size of the earth. Makes you go "Hmmm".

The small sphere respresents all the volume of water on the planet literally rolled up into a ball and juxtaposed against the barren earth.  I would like to see extracted from this sphere another one showing the size how much of that is drinking water and not sea/salt water.  Pretty amazing.
