People are major pollutors of Earths fresh water supply.
The total amount of Earths total water supply that is usable fresh water is less then two percent. The rest is salt water or pond water.
Glaciers
The Great Lakes contain about 84% of North America's surface freshwater supply, which is roughly 21% of the world's surface freshwater supply.
Most of Earth's fresh water is locked up in glaciers. "Supply" would reference rivers and lakes.
there would be less evaporation and so less rainfall and as a result less fresh water
It is frozen into polar ice caps and glaciers.
The water cycle ensures that water gets used again and again by constantly recycling water through processes like evaporation, condensation, and precipitation. Water evaporates from bodies of water, condenses into clouds, and then falls back to the Earth as precipitation. This cycle repeats itself, allowing water to be used over and over again.
three percent of all the earths water is fresh water
Yes water cycle use up earths supply. Water is evaporated from earth's surface.
3% of the earths water, is fresh water
It is frozen into polar ice caps and glaciers.
