WATER RESOURCES ON EARTH
THE AMOUNT OF WATER ON EARTH HASN’T CHANGED SINCE THE PLANET WAS FORMED TWO
BILLION YEARS AGO.
THE WATER THAT COMES FROM YOUR FAUCET COULD CONTAIN MOLECULES THAT DINOSAURS
AND NEANDERTHALS DRANK.
APPROXIMATELY 97% OF THE WATER ON EARTH IS SALT WATER. ONLY 3% IS FRESH WATER. OF
THAT 3%, MOST IS FROZEN IN THE POLAR CAPS OF ANTARCTICA. THE REMAINING 1% IS FOR ALL
HUMANITY'S NEEDS.
