Are We Running Out of Pure Water?
Water is a life giving substance! We are confident that life as we know it cannot exist without the presence of clean water. We can live weeks without food but only days without water. Recent tests on the moon were designed to detect any presence of water, for eventual colonization would be impossible without it.
The earth is not short of water as such. It contains 326 million trillion gallons of water, meaning we could each have our own 56 billion gallons. The average person in the world has a daily requirement of water for sanitation, bathing, and cooking needs of about 13.2 gallons. That means the world contains enough water to last each of us over 11 million years (not counting population growth)! That doesn’t take into consideration the free recycling system provided for us called evaporation and condensation.
The problem is that most of this water is unusable in its present form. Ninety-eight percent of the water on the planet is in the oceans, and is, therefore, unusable for drinking because of the salt. Of the 2% of the planet's fresh water, 1.6% is unusable in the polar ice caps and glaciers. Another 0.36% is found underground in aquifers and wells. Only about .036% of the planet's total water supply is found in lakes and rivers. That still provides 392 million gallons for each of us. The sobering fact is that only about 0.007% of all water on earth (and less than 1% of the world’s fresh water) is accessible for direct human use.
The problem is bad also because useable water is not evenly available to the world population. For example, the average American uses more water in one shower than most third world people use in a whole day. Nearly one billion people of the world do not have access to safe water. More precisely 884 million people lack access to safe water supplies, approximately one in eight people. Further, two and a half billion do not have improved sanitation, that is, a means to separate drinking water from waste water.
The lack of sanitary drinking water results in major health issues throughout the world. As many as half of all people in hospital beds at any given time are there because of a water related disease. As a result, a child dies from a water-related disease every 15-20 seconds in the world, usually from diarrhea. That is 1.4 million children each year. The children in these environments often carry 1,000 parasitic worms in their bodies because of stagnant water supplies. We are told that 88% of cases of diarrhea worldwide are attributable to unsafe water, inadequate sanitation, or insufficient hygiene.
Poor water results not only in deaths, but also in more crime, more disease, increase in birth defects, and decreased ability to do well in school, among other things. In short, it results in general economic decline. An investment in pure water for a people, or in desalination of the sea, is an investment with big returns. It is estimated that on average, every US dollar invested in water and sanitation provides an economic return of eight US dollars.
Some want us to live like they do, not watering our lawns or taking a shower as often. This reasoning is flawed. Lowering our living standard in use of water only takes on their problems as our own. America has good, clean water because we have learned where to find or clean it, and how to preserve it. Our response to criticism should not be guilt but better stewardship and an increased willingness to share our knowledge with others. When our water systems are conserved and maintained, America will continue to set a high standard for others to follow.
But what if you are on well water or city water that has bad taste or odors. You would be benefited by an activated charcoal water filter. The Berkey Water Filter are the best line of activated charcoal filter we are aware of. Check out the Big Berkey or another model. One amazing feature is that each set of filters they ship with can be re-cleaned to purify up to 6,000 gallons of drinking water.
Recycle Sea Water?
Tell me this, the ice bergs are melting and the sea level is rising yet in the UK we have hose pipe bans because there is not enough water. Waste water gets cleand and recycled so we can drink and wash with it, why can we not do the same with the sea? there is so much of it and it would solve so many problems. If they can clean and purify other water why not the sea?
What are your views?
I appreciate there is marine life in the sea and i'm not suggesting we use it all as the mammals need to survive. But that there be a limit to the amount used,
Every ship uses desalination for there drinking and shower water. It is simply salt water boiled and the steam separated then cooled from evaporation into fresh water and treated with the normal chemicals used in every day water consumption. It's acutually cheap to do and produce. You can do it at home. I was a boilerman and a water tester in the Navy for six years. But just try to get the Government to do something cheap for the people and not receive a lot of revinue from it and you got world war three started.

Inhabitat's Week in Green: electric taxis, paper robots and a cathedral of 55,000 LEDs (Engadget)
_Each week our friends at Inhabitat recap the week's most interesting green
developments and clean tech news for us -- it's the Week in Green._
This week Inhabitat saw the light as we reported on several spellbinding new
projects around the world -- including an incredible cathedral made from
55,000 LEDs and a glowing prefab pod building modeled after the genetic
structure of plankton. We also showcased a luminous forest of thousands of
"Frozen Trees" and a high-flying F-Light made from a recycled airplane, and
also reported on Toshiba expanding its line of LEDs. Meanwhile, as the lights
fire up Lucas Oil Stadium we shared seven ways Super Bowl 46 is going green,
took a look at the first organic concessions ever to offered at a Super Bowl,
and got things cooking with six delicious recipes for game time snacks
Eco transportation also blasted off from the starting line as London's first
zero-emission electric taxis hit the streets, and Stanford unveiled plans for
electrified roads that automatically charge EVs. We also saw Scotland launch
the world's first hybrid sea-going ferries, while Agence 360 did cyclists a
favor by designing a nifty ultra-compact foldable bike helmet. ...
