Water crisis? What water crisis?

Though you wouldn't know it from the way we use it, fresh water is one of our most limited renewable resources. Here are some water facts that might surprise you.

Fresh Water is Scarce

Most of the Earth's water is saltwater (97.5%) with much of the remaining freshwater frozen in polar ice or otherwise inaccessible to us. In fact, humans and all other life that requires freshwater must share less than 0.5% of the water on Earth. That's only about the size of this marble in comparison to the size of the Earth.
