Dry EarthAs a child, you are told a lot of things about this great planet of ours. We are the third of nine planets in the Solar System (now eight and one dwarf planet), Mount Everest is the tallest mountain on the planet, and the Earth's surface is 70% water. With a figure like that, it's easy to assume that water is pretty much an infinite resource. However, according to the U. S. Geological Survey, if you were to take all of the water on the planet (including fresh water, sea water, ground water, water vapor and water inside our bodies), it would only make a sphere 860 miles in diameter. 860 miles!? You can drive that in a day - it's about the distance from Salt Lake City to Topeka, Kansas.1
