Probably the most vital tangible need of humans is water. Greg Davenport, Survival Expert www.gregdavenport.com, says that you cannot go without water for more than a few days.
As www.wilderness-survival.net points out:
Water is one of your most urgent needs in a survival situation. You can' t live long without it, especially in hot areas where you lose water rapidly through perspiration. Even in cold areas, you need a minimum of 2 liters of water each day to maintain efficiency.
More than three-fourths of your body is composed of fluids. Your body loses fluid as a result of heat, cold, stress, and exertion. To function effectively, you must replace the fluid your body loses. So, one of your first goals is to obtain an adequate supply of water.
Wilderness Survival has a great template on how to find water in different geographic locales, http://www.wilderness-survival.net/water-1.php .
In the city, it would be wise holding some bottled water. With droughts, rising water bills and an unstable economy, it is good to be prepared with some water 'on tap' (pun intended). At a minimum, you should have a few days of water, if only for a natural disaster event.
Over at Alex Jones' website, www.infowars.com , there is a link to www.ecoloblue.com.
Ecoloblue is a 'water generator' that pulls the humidity out of the air and converts it into "pure, renewable water."
