The problem goes beyond one or two situations, and sooner rather than later will affect us all. We need a comprehensive approach to the problem, according to some, will cause the next global conflict.

All good (naturally or artificially) acquires a price, the more scarce, the higher its price, gold, diamonds, uranium, petroleum, including drugs, get their value depending on the difficulty in obtaining them. At the other extreme, abundant and easy to get goods are priceless, air, light and heat from the sun, sea water, sand in the deserts and almost anything else, are free goods. The water was cheap or free only in areas and times where it was sufficient or exceeds demand.

The only possible way to keep the water at a suitable price range and therefore, out of the pressure for privatization and abusive commercial exploitation, is the research and technological development that allows desalination of sea water at low cost, at ranges that, any individual or community can implement it, if they do not have drinking water at a reasonable price. This manifests itself in all its importance the need to develop energy and passive environmentally friendly and economical to allow, in combination, the type of development that requires, for example, desalination of sea water on a large scale.

Wind power generators, or the movement of waves, or others, to bring water from sea level to areas where is needed. Evaporators of solar energy or other low-cost and high efficiency, to produce fresh drinking water at a low cost, will be in the medium to long term, the only ways to drinking water in quantity and quality needed, and for make not too attractive the business with it.

The world economic system is not really interested in these developments, because the market to survive, requires that property or goods permanently increase its price. I work in these fields for years, but the difficulty is to obtain the resources to develop systems and build prototypes for testing and refinement. In my country, including obtaining patents worldwide is cumbersome and full of obstacles.

The cases of Bolivia and New Orleans are early symptoms of a global problem, which fortunately have been neutralized with the pressure, but although they solve the symptoms, they have not solved the root of the problem, what is I suggest to do. The case of Bolivia is the most extreme, over 10,000 feet above sea level and has no access to it. There should probably be obtained from other sources of water, snow, ice, accumulation of rainwater, groundwater sources, and so on. With economic energy sources, it would be possible to obtain without having to raise it to that height. Anyway I have no doubt, that its neighbors would give them access to sea water, if it is their best option.
