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.
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.
