One of those delicious infographics1,2 that allows you to grasp an idea at a glance. In this case, it is not new, but I bet it is an idea (and a representation) which will gain a lot more relevance in the coming debate.
How Much Water is There on Earth? All of it in just three bubles. (Make sure you do not lose sight of the third one!)
- (1) All water (largest sphere over western U.S., 860 miles (1,385 kilometers) in diameter
- (2) Fresh liquid water in the ground, lakes, swamps, and rivers (mid-sized sphere over Kentucky, 169.5 miles (272.8 kilometers) in diameter), and
- (3) Fresh-water lakes and rivers (smallest sphere over Georgia, 34.9 miles (56.2 kilometers) in diameter).
