A 2-Tablespoon Freshwater Tap every 12 feet!

Seeing IS Believing except when the subject is freshwater. We usually conclude that there is no water when we cannot spot any where we are looking.
Water in Air Is nearly all in Vapor Form

The moisture in the air is essentially in vapor form and our naked eyes cannot see any gas or vapor.
Clouds are visible to us because of the liquid water droplets that are dispersed in the air that makes up the cloud.
Fog is another example of us being able to see the moisture in air because some of this water exists in liquid form.

NOAA/ESPL have mapped the moisture in the air we breathe i.e. in the air at sea level.
The average water content of this air - the air all around us and the air we breathe - varies from a low of approx 2.4 grams per cubic meter to a high of approx. 24 grams per cubic meter. The maximum amount can even exceed 26 grams per cubic meter but this concentration exists in only a very few places.
Water Amounts in Air

Using the conversion (1 cubic centimeter (cc) of water weighs 1 gram) the moisture in 1 cubic meter of air varies from approx one-sixth of a tablespoon to over One-and-a-half tablespoons.
Thus, approx. 16 cubic meters (565 cubic feet) of air contain a cup (16 teaspoons) of water. Or, the air in an average sized room 8.5 feet high, 12 feet wide and 12 feet long contains a bit more than 2 tablespoons of safe water! 

All that remains to be accomplished is to capture this water for local use. Isn't this a challenge worth overcoming?

Is Any Place FREE from Potential Safe Water Risk?

Water risks come in many forms and if "amount of safe water" is used as a measure, then too-much water (flood) is one extreme while too-little water (drought) is the other extreme. Other measures that define risk are quality, limitations imposed by nature or constraints imposed by a lack of water supply infrastructure.
Flood Risk

World Resources Institute's AQUEDUCT Project has mapped the occurrence of floods in the 1985-2011 period. Some interesting observations:
- The Eastern half of the US has experienced many floods; Much of Western Australia has had to cope with floods; Floods seem to cover all of South Asia and the Middle East excluding countries that have predominantly desert landscapes; Mid and Eastern Africa have needed to cope with floods; etc.
Areas free of foods include:
- Mid and south-western US; Much of Canada; Northern regions of Russia and the Scandinavian states; Southern tip of Africa; Midsection of Australia; etc.
Drought Risk

Another map from the AQUEDUCT Project displays drought locations during the 1985-2011 time period. Some conclusions: Australia's midsection and west experience drought; The US west coast and western states are drought prone; Northern and southern Africa have experienced drought frequently; Canada's midsection will see drought as will north and northeastern Russia; The Scandinavian areas free from floods have seeen many droughts; etc
Combining Risk of Flood and Drought
A most interesting and ominous conclusion surfaces when the two maps, flood history and drought history, are superimposed: there seem to be very very few areas where water, as drought or flood, does not pose a hazard to humanity and, also, nature:
- Much of Australia, the US, Africa, Europe, Russia, the Middle East. Canada, etc have been prone to risks from water, either as drought or as flood.

Safe water is a worldwide issue! Very very few of us will not face some form of water insecurity in the near future. We are all in the same boat where safe water is concerned!
