What other way would you want?

Challenged in September 2010 to come up with interesting facts every day by one of my work colleagues, I've since entertained him and those near his desk with bits of information dredged from my brain. Some of my audience went on holiday and still wanted the facts so I started posting here, every day I do one of them, usually Monday through Friday, and the occasional post on the weekend. I post these facts here almost every day and you will find two posts on some days to make any missing days.

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.
