Today’s interesting fact has to do with fresh water.

Fresh water accounts for about 2.5% of the water on the earth.

The rest, 97.5% is salt water.

Of the fresh water availble on the earth, less than 1% is available to humans, and is found in lakes, rivers, resevoirs, underground aquifers we can afford to tap.  This fresh water is renewed only by falls of rain and snow.

70% of all the fresh water is tied up in ice caps on Antartica and Greenland.

The other 29% of fresh water is tied up in soil moisture, deep underground aquifers and moisture in the atmosphere as vapour or clouds.
