Water

An important feature of this planet where we’re living in is the omnipresence of a mineral which abundance is often not valued, the water. Obviously the areas where this mineral is rare for immediate use is considered an object of great value, but majority places it hasn’t value. Currently the overpopulation this vision is changing, and usually we begins to have a perception of scarce resource, which is not entirely true, although it should take measures to ensure this doesn’t end up being a reality. It’s affirming that future wars will be with the water, and I don’t doubt that it will end up being true, but mainly by incompetence and lack of vision, responsible for most of human disasters that happen to us, not by lack of most abundant mineral in the earth's crust.

This planet is the son of the water. But part of the basis of life also involved in most geological processes and rules the climate. Ultimately it is the agent that makes Earth so different place from the rest of the Solar System. It’s part of the rocks when it isn’t a rock itself in cold weather. At the same time it constitutes more than 70% of any living being including those is living in dry environment. However life hasn’t it only with support, but it’s a part of many interacting processes and solvent of all them.
Water is the third abundant gas in the atmosphere. Normally we haven’t in mind because we always refer to the concentration of dry air (without water). This distinction is due to the concentration of water in the atmosphere ranges from a nearly 10% in extreme cases up to 0.5% and so on depending on the temperature and geography. This variability makes it even more important because this is precisely the main engine of world weather. Different concentrations are due that atmospheric temperatures and pressures are nearly to the triple point of it, this allows any phase change with only a little fluctuation of both variables. So it the loss of pressure due the rise condensed water that still produces a greater pressure drop due to the disappearance of water vapor in air, and consequence the drop of temperatures; this thing seems contradictory because condensation must release heat, and this thing happen, but the expansion cooling due to the disappearance of moles of water is higher of order in this case. It is important to note that this same mechanism for different boundary conditions can cause the contrary effect, as I explained many times (Feedback, Really are temperatures stopping its rice?) weather is not linear mechanism which can evolve differently depending on the boundary conditions. At the same time we find the otherwise, the air near a mass of water in evaporation absorbs water, as water molecules weigh less than O2 and N2 (main gases in the atmosphere) and it causes displacement (more water molecules rests molecules of other gases) wet air is less weight than dry above it that facility the changing between masses of air; this mechanism isn’t so directly that we can think, so heavy cold dry air is usually above us for luck, because it allows the current life. Exists a significant number of situations where the phase change of water generate changes in air masses, in short the omnipresence of this mineral is differential climatic factor on our planet (because all planets have climate but it have nothing to do with our).
The planet has a record temperatures combined with atmospheric pressure allows at this mineral change of phase with relative ease. The distinguishing feature of our planet is the phase shift precisely because there are water in all the planets, although the rocky interior, which the Earth is part of them, is what apparently* has much more. The reason for this isn't too clear. Probably has to do with his position, although it would not be anything definitive. Radiation depends on the position but without the presence of water in gaseous form, the Earth would have a similar temperature and atmospheric pressure on Mars because water is the main greenhouse gas on the planet; indeed Mars was like Earth 4,000 million years ago. And this brings us to next question: Why Mars and Earth are as they are? This question is not trivial, and it is now very clear answer. In this context Geoengineering or Terraforming are still some proposals Sorcerer's Apprentice, began to manipulate global variables of a planet is only one more act of human hubris can get very expensive.
The lack of human imagination creates true monsters. Obviously, drinking water is scarce in the world and more when the demographic pressure and futile uses generate drought at the smallest fluctuation in rainfall. Today we suffer drought more of stress imposed on the resources than the lack of rain. On the other hand urbanization of ever larger tracts of land leading to flooding both reduce absorbency and to invade the land areas of the course. An example is the Danube River, which was described by the Romans as a swampy area where it was impossible to distinguish the edges, but is now fully ducted and as a result when it rains over than normal, there are floods. In fact every year there is floods in a European river, climate change? Not simply have invaded their natural areas of expansion. So to avoid this problem created by humans, where we try to construct large dams where we regulate the flow of these rivers, "the triumph of man over nature"; which serves to store water for drought and produce "clean" energy. Although the dams are usually more problem than solving: hydroelectric energy generated sudden changes in flow when it is low creating serious problems in biology river, in another band that never generated floods enabling algae and plants grow in areas of fast course, which hinder the flow when the swelling is inevitable increasing effect; store water is also bad business, most of the water stored there is anoxia (without oxygen) a real poison, these lakes evaporate large quantities of water in normal course would fill aquifers where it never evaporates; and regulate the rivers when it doesn’t rain, when it rains have also opened floodgates to drain causing flooding that supposedly would prevent. In short the dams are great infrastructure artificially flood a valley, cut off the flow of sediment over time are missing academic down, they destroy the life of the river because they disrupt biological flux, and when the need can’t be used because nature is more powerful than we had expected, the best solution would be to find a better solution and to dynamite all them. While water is a matter public construction continued to suffer droughts and floods because water is malleable but not cement.
In the early twenty-first century, with the prospect of climate change and a crisis of operation, we continue mistreating this abundant mineral cheaper but with priceless. Some time ago I talked about the difference between value and price. Currently confuse these two concepts generated wars by oil while messing water sources that ultimately will be impossible to survive in those areas, as in the Niger Delta or Facking nonsense. Really forget that we are drops of water walking and our destiny is linked to this mineral which is so humbles that hasn’t: color, smell and taste.
 
*it can’t make sure because every day we find more water in planets and satellites.
