What is the reason for water conservation?
I say that its all about money, since filtering, desalination, chlorination, and transportation of seawater is possible. The only way water can be destroyed is through electrolysis or other chemical process
Even if water evaporates, it will not leave the atmosphere.
Are these things possible? Sure. Is water renewable? Theoretically–it does evaporate and rain and so on. But particular freshwater supplies are very limited, not only in the desert. Often they draw on groundwater ("fossil water") which takes millennia to accumulate and will not be replaced in anyone’s lifetimes. The Ogallala Aquifer is millions of years old and is beneath six states in the center of the US, forming a large portion of the water taken for domestic use and irrigation. When it’s gone, many of those cities from Texas won’t have much of a water supply.
If you care about energy use and global warming, realize that water filtration and all the other methods you mentioned aren’t cheap energy-wise. Not to mention desalinization of seawater is incredibly impractical, at least with today’s technology.
Freshwater is only 3% of all water on earth, and of that, less than 1% is liquid and above ground. Just some perspective.
I hope that helped.
You know the earth is suffering from Global Warming and the ozen layers is already destroyed. So when the sun rays will start coming directly on the earth all the water will go away from us. So try to save it.

In some desert areas where water is scarce, this makes sense, but 99% of the time it’s complete BS.

man not that this has to do with you question completely but if i am willing to pay extra for the water that i use i think the need to supply it!!! then on the news i saw people conserved so well that the water company had to raise there bills…..what a way to congratulate people….i hate the water company….antioch ca water isn’t even drinkable…..WHAT DO WE ALL PAY FOR!!!!!! =]

Though 80% of earth is made of water, only 1% of it is fresh water. It’s only 1% that we can use for drinking, irrigating, washing etc. Hence it’s very important that we conserve water. Fresh water reserve levels have started to drop in may places. For instance if you go to http://www.bewaterwise.com/ you’ll see a water gauge indicating how much the water level has dropped since July 2006 in Southern California. We need to put a check to this through water conservation. Here are some tips on how to conserve water at home: http://www.bewaterwise.com/tips01.html
Please check them out and also spread the word among all fellow Southern Californians!
