The water is one of the most indispensable resources for the life in the land, and nevertheless the man wastes it without measure, of a form or other one, the best way of offsetting this problem is concientizar to the persons on the rational utilization of this resource. The water occupies the great part(report) of the terrestrial surface, and in the main it is a salty water, which is not suitable to drink. Also our body is formed(trained) by 70 % of water, the water is not alone essentially for the human beings, but for the animals, the plants(floors) and the whole life of the planet. Because of it, by means of this work of investigation brings over of the evil that attacks the essence of the water; we seek to give possible solutions, to which(whom); should to worry from a point more general, because ... What would happen if we live without water?...

To all those persons who, with effort and dedication, manage to

obtain what they propose: the success. Because with humility it

comes near everywhere...

The water not only is an essential part of our own physical nature and that of other alive beings, but also he contributes to the general well-being in all the human activities. The water is in use mainly as indispensable element in the diet of every alive being and this one is one of few elements without which one might not support the life. For all that the water offers big benefits to the man, but simultaneously it can transmit diseases, as the cholera. The water that comes from superficial sources(fountains) (rivers, lakes and gullies), is an object day after day of a severe pollution, product of the activities of the man.But, what would happen if this does not happen?...

The water has a double action on the health. In normal conditions it diminishes the possibility of contracting diseases as the cholera, the typhoid, the dysentery and the diseases diarreicos; it finalizes this one is the principal reason of mortality of the children of 1 to 4 years. It removes the materials excrementicos and residual.

The growth of the industrialization, of the urbanization and of the human population acercienta the problems of pollution and in consequence the supply of drinkable water and the treatment of the waters. Apart from all that, the water is the vital element for the nourishment, hygiene and activities of the human being, the agriculture and the industry. Because of it, the hygienic requirements are more rigorous with regard to the water destined for the consumption of the population, requirements that be being less and less satisfied, for his pollution, which reduces the quantity and quality of the available water, as also his natural sources(fountains). “Because of it, if you contaminate your own water, you contaminate too what you consume”

The effects of the pollution of the water include those who concern the human health. The presence of nitrates (you go out of the nitric acid) in the drinkable water can produce a childhood disease that in occasions is mortal. The present cadmium in the fertilizers derived from the ooze or mud can be absorbed by the crops; of being consumed in sufficient quantity, the metal can produce a disorder diarrheic sharply, as well as injuries in the liver and the kidneys. Some time ago that knows itself or is suspected in the dangerousness of inorganic substances, as the mercury, the arsenic and the lead.The lakes are specially vulnerable to the pollution. There is a problem, the eutrofization, which takes place(is produced) when the water prospers in an artificial way with nutrients, which produces an abnormal growth of the plants(floors). The chemical fertilizers dragged by the water from the fields of culture(culturing) can be the persons in charge.And this ... does not it worry you?

•Activity Industrial.-Any organization, company or industrial activity affects the Environment across his activities, products or services. This includes not only the extraction and exploitation(development) of the natural resources that the environment provides us, but the elimination to the same one of those residues or tailing that ensue from such activities and that, depending on the conditions and places in which they are eliminated, can cause a major or minor degree of hurt or environmental impact.For example, the industrial activity of diverse types that develops in the country, constitutes an important pollution source, due to the fact that his tailing or industrial liquid residues (riles), or solid (rises), are evacuated directly or indirectly to the terrestrial environment, in some cases without any type of treatment, or in others with deficient or insufficient treatments, causing with it consequences or serious hurts to the environment.

• The acid rain.- This one appears as a rain common and current rainfall or in the shape of snow or fog only that presents a minor pH that that of the water of 5.65 to minor quantities. This happens due to the fact that in the atmosphere there settle substances that acidify or acquire the acid condition during the rainfall.

• Residues Inorganics.-The pollution of the water can be given in sanitary not designed landfills following(continuing) technical procedure. This way, there can be pollution of underground waters or of superficial bodies of water by water of run-off. For the specific case of the burning of garbage, pollution of the water will exist if the produced particles come up to water bodies. There can be pollution by means of the production of machines that are the substances proceeding from the rotten garbage and that filters to the soil by means of the water.

If since before it has been mentioned, every 11 years the Sun raises his heat, inside several thousands of years (... let's wait) for the poles there will have been melted increasingly that entire cities in the whole world were remaining flooded, the whole water will be salty, there will come a moment in which we will live through a deluge and every living being will die after a cycle of life in which they will have to adapt to the way that it will be born. And finally the planet will be flogged by planetary garbage, will be a piece of dead planet and the Sun will run in order any star, his heat will come a limit in which it will evaporate the whole water that it will cover to the planet, this one with his heat will kill it, if it is that a meteorite is not anticipated(advanced), and the great star will go out and eliminate like any other one. It sounds apocalyptic, but this will happen according to realized studies. Still we do not know when it will happen, but already we are in the regressive count…Would you do something for solving this?...

Ozone, the hole remains... Before it happens they all this were spending(passing) thousands of years, probably up to millions but it depends on how it increases the pollution and since the hurt grows to the cap of ozone. Now we live through the greenhouse effect, what is? Caused by the consumption of fossil fuels that cause overheating of the atmosphere for the emission(issue) of carbonic anhydride, CO2, in 1999 there were burned about 7600 million tons of fossil fuels, with an increase of consumption of natural gas and oil.The experts of the UNO (United Nations Organization) believe that the terrestrial oven will become overheated 5 degrees during the next century. Diverse companies of the energetic sector already are employed at effective mechanisms to reduce the greenhouse effect. The scientific community is optimistic due to the restrictions of emission(issues) of clorofluocarbono and gases toxin from vehicles; haloes and gases responsible for the hole of ozone, this shield that protects to the terrestrial surface of them beam UV from the Sun.Now yes to worry?...

GALLERY OF PHOTOS

Often, we are conscious that day after day we contaminate the water, but we do not realize that we are destroying every second of our lives; to sorrow(despite) that in many places, specially in the arid zones, the water is very scanty, this one is wasted of many forms...And you ... what harías'para to anticipate(prepare) this?...

Often we do not realize that the residue that the desagues express(emit) they contaminate the rivers of an indirect form; harming this way the existence of the animals that there they live(inhabit)...So(Then), what would you face all that?...

Observe you these images; and you thinks for a moment...

Instead of trying to control or to handle the spillages or to invest in millionaires systems of treatment of effluent, the progressive reduction of the generation of pollutants by means of the reduction of the use and production of residues; because not podrìa to be that of soluciòn to these problems; that day to day be isolating the water? ... What do you do will to anticipate this?...

A lot of varieties of maritime species die day after day for reason of this world discomfort... We us Must put the hand to the heart; and to think...What would happen if these species escacean completely?...

POSSIBLE SOLUTIONS BEFORE THESE PROBLEMS...

To treat the water in prestigious industries; in order they to be used parael by human and environmental use; it is an initiative of progress...

Lagoons of oxidation... New ways of treating the most special water of a form; since there is suitable also the presence of a good economy to achieve this...We all the united ones can!...

Companies that they dazzle to the world...Why not to use them in the special treatment of the water?...

If we all join in collaborating with the care of the water...What would be of our existence?...

A POETRY OF REFLECTION...

This fresh exchequer, be useful we good, calm our heats, priest our heavy thirst.

This beautiful exchequer keep we better that to a toy, amémoslo better that to a flower.

Why do we hate to these white balls and of cotton?

They bring this good gift.

Look how they suffer the camels in the warm deserts!

They are strong, but they need it longingly.

The water costs very much, the people who does not have it go suffer!

What luck! We have a benediction the clean water the rivers, stop contaminating it or it will be worse.

What pleasure we have!This freshness that drowns our weepings, the child likes as game;And it is the principal thing for our food.
