Earth has a limited amount of freshwater because most of the planet's water is saltwater in oceans. The remaining freshwater is contained in glaciers, ice caps, and underground aquifers, leaving only a small percentage available for human use. Climate change and pollution are also putting additional pressure on the freshwater resources we have.

What is 70 percent of Earth's freshwater?
In a way, 72% of Earth approx. is covered in water. Only 3% is freshwater. So only 4% of earth is freshwater. 2/3 of that 3% is locked in ice caps. So 2.7% of earths water is frozen. Only .75% of Earths water is in rivers. That is hardly 1% of space on Earth. The rest is frozen in Glaciers, which is .25%. Only .03% of Earth is made up of Glacial ice.

What percent of earths fresh water?
Yes. About 3% of the water on Earth is "fresh water" (not salt water), but 2/3 of that is locked up in sea ice, glaciers, and ice caps. So about 1% is "available fresh water" and most of that exists in underground aquifers, which is not always renewed as fast as it is used. Only about 1/100 of 1 percent of the total fresh water is present in springs, rivers, lakes, and swamps.
