Water wars could become more than theoretical

Hmm...
The planet earth contains more water than any other solid materials. But the majority of water resources on earth are salty water that are not possible to drink like fresh drinking water.
But yet it is possible to desalinate (separating salt from water) salty water and it is being used more and more around the world to provide people with needed freshwater. Water that is saline contains significant amounts of dissolved salts. In this case, the concentration is the amount (by weight) of salt in water, as expressed in "parts per million" (ppm). If water has a concentration of 10,000 ppm of dissolved salts, then one percent of the weight of the water comes from dissolved salts.
The scarcity of freshwater resources and the need for additional water supplies is already critical in many arid regions of the world and will be increasingly important in the future. Many arid areas simply do not have freshwater resources in the form of surface water such as rivers and lakes. They may have only limited underground water resources. Solar desalination evaporation is used by mother nature itself to produce rain, which is the main source of freshwater on earth. So my thanks for mother nature for now and in to the future.
Another method saline water is desalinized is by the "reverse osmosis" procedure. In most simplistic terms, water, containing dissolved salt molecules, is forced through a semipermeable membrane (essentially a filter), in which the larger salt molecules do not get through the membrane holes but the smaller water molecules do. Reverse osmosis is an effective means to desalinate saline water, but it is more expensive than other methods. As prices come down in the future the use of reverse osmosis plants to desalinate large amounts of saline water should become more common. This in turn needs our common home work instead of the usual war talks.
Distillation or desalination is one of mankind's earliest forms of water treatment, and it is still a popular treatment solution throughout the world today. In ancient times, many civilizations used this process on their ships to convert sea water into drinking water. Today, desalination plants are used to convert sea water to drinking water on ships and in many arid regions of the world, and to treat water in other areas that is fouled by natural and unnatural contaminants. Distillation is perhaps the one water treatment technology that most completely reduces the widest range of drinking water contaminants.
By inexpensively turning salt water into drinking water using sustainable solar power, a team from MIT in the US has not only come up with a portable desalination system for use but also offers it anywhere in the world that needs it.

This means, "BINGO! WAR IS NOT THE ONLY OPTION!"
