Where is freshwater located?
Only a tiny fraction of the planet's abundant water is available to us as freshwater. About 97.4% by volume is found in the oceans and is too salty for drinking, irrigation, or industry (except as a coolant). Most of the remaining 2.6% water is freshwater and locked up in ice layers or glaciers or it's too deep underground to be reached or too salty to be used. Thus, only about 0.014% of the earth's total volume of water is easily available to us as soil moisture, usable groundwater, water vapor, and lakes and streams.
