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: -According to the U.S. Geological Survey, most of that three percent is inaccessible. Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.
Detailed explanation-3: -In the first bar, notice how only 2.5% of Earth’s water is freshwater-the amount needed for life to survive.
Detailed explanation-4: -Of all the water that exists on our planet, roughly 97% is saltwater and less than 3% is freshwater. Most of Earth’s freshwater is frozen in glaciers, ice caps, or is deep underground in aquifers.
