Detailed explanation-1: -Fresh water makes up under 3% of all water on earth, and nearly 65% of this drinkable water is tied up in glaciers. Rivers, streams, lakes, and dams that hold freshwater contain 1% of potable water while groundwater accounts for 0.3%.

Detailed explanation-2: -In the first bar, notice how only 2.5% of Earth’s water is freshwater-the amount needed for life to survive.

Detailed explanation-3: -Only about three percent of Earth’s water is freshwater. Of that, only about 1.2 percent can be used as drinking water; the rest is locked up in glaciers, ice caps, and permafrost, or buried deep in the ground. Most of our drinking water comes from rivers and streams.

Detailed explanation-4: -The ocean holds about 97 percent of the Earth’s water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes.

Detailed explanation-5: -Our freshwater is locked up in the Antarctic Ice Sheet. About 71% of the Earth is covered in water. Most of that is in oceans, rivers, and lakes, but some is frozen in the Earth’s two ice sheets.
