Don't we feel the abundance of water on Earth five that 75% of the surface is covered with it. But here are the facts: "WATER IS SCARCE"
"-Blue spheres representing relative amounts of Earth's water in comparison to the size of the Earth. Are you surprised that these water spheres look so small? They are only small in relation to the size of the Earth. This image attempts to show three dimensions, so each sphere represents "volume." The volume of the largest sphere, representing all water on, in, and above the Earth, would be about 332,500,000 cubic miles (mi3) (1,386,000,000 cubic kilometers (km3)), and be about 860 miles (about 1,385 kilometers) in diameter which is about 11% of Earth's diameter of 7917 miles.
-Smaller sphere over Kentucky represents Earth's liquid fresh water in groundwater, swamp water, rivers, and lakes. The volume of this sphere would be about 2,551,000 mi3 (10,633,450 km3) and form a sphere about 169.5 miles (272.8 kilometers) in diameter. Yes, all of this water is fresh water, which we all need every day, but much of it is deep in the ground, unavailable to humans.
-The vast majority of water on the Earth's surface, over 96 percent, is saline water in the oceans.
-Ice caps, permanent snow and ground water represent only 1.75% of the total water but account for 68.7% of all freshwater."
