All the water on earth

Here is a picture that shows the the size of all the surface water on the earth gathered into a ball. I find it amazing that there is so little water compared to the size of the earth. It also shows side by side the amount of water in Europa (which is smaller than our moon) has more water than the earth.

Since we humans are more than 90 percent water, it raises question on our importance!
