Earthfreshwater-490x500

The sphere on the left represents all the water on the planet:

If you gathered all the world’s water—from oceans, lakes, groundwater, water vapor, everything—into a sphere, it would have a diameter of 860 miles. That’s the distance between Salt Lake City and Topeka, Kansas.

Jay Kimball graphed just how little of that is fresh – the sphere on the right. Coby Beck heightens our worry:

And don't forget that that ball of freshwater is mostly out of range of our drinking glasses and irrigation systems. A full 74.5% of that much smaller ball is locked away in ice caps and glaciers and 24.7% is groundwater (much of that out of reach). There is only .56% of the world's freshwater circulating in lakes, rivers, rainfall, soil and the biosphere.
