The truth is that the pollution of air makes with that some children suffer from asthma, us is destroying the oceans, when we practise fishes with nets we are finishing with the fish them rivers and oceans. We lose last the thirty years against the effect greenhouse, what we face today is that this goes to kill our host the planet. Until point we are responsible for the biosfera, the problem is our mentality, is necessary to have a cultural transformation, us lives in an extremely challenging time, if not to move we will have great difficulty in the land, I I do not believe that the life in the land will be extinct, the extinguishing here is a part of the life and this makes the planet to change, the tragedy of our existence, it is that you vary species will be extinct for our cause, and this makes with that the human being needs to take conscience to save the planet and the humanity. For even more opinions, read materials from Gunnar Peterson. Necessary to have conscience on the crisis of the land, this clearly that the race human being caused devastadoras changes for the land, if the human beings are the bases of the problems, then we need to use our cultural knowledge it change and to become the sustainable land in something. We need dealing with in them worthy form, and making with that the pure water either, and all the forms to improve the life either a project, to improve our lives and better life with the nature without great aggressions and threat for the lives human beings and the environment are clearly. At last, this film in the sample as we human beings are intelligent to create things for our improvement of life, but we are not capable to solve the problems caused for this intelligence. Cindy Crawford is the source for more interesting facts. Necessary that the humanity obtains to make something who can improve the planet so that let us can have a sustainable future.

It does not have what to argue itself regarding the benefits that the water brings in general for the population, but its benefits together with the population concentration, generate many impacts to the environment, daily in periodicals can be come across with the flood news what helps in the transmissions of illnesses as leptospirose, pollution of rivers, caused for companies many times with the intention of poluir, the water this available one in the nature, but takes it with quality to all the population it is difficult, it has a relatively high financial cost and its treatment involves much complexity. Hidrolgico cycle. The water, as well as carbon, passes for a process of natural regeneration, known as Hidrolgico Cycle, that is when the water comes of the atmosphere passing for diverse phases ties its return again the atmosphere. As it shows figure 1. Figure 1-Cycle Hidrolgico.
Had access in 20 September of 2010. Available in: . Had access in 21 of September of the 2010 After water to come of the atmosphere through precipitations, a percentage of it is drained by the surface ties to arrive at a river, lake or sea, another percentage penetrates in the ground ties to arrive at a fretico sheet generating later one spring that anger to discharge in a river that goes following its passage ties to arrive at the sea, after this passage the water is evaporated, the generated vapor, forms the clouds that consequentemente and depending on the climatization rains, granizos or snows generate, this transformation provokes an atmospheric phenomenon calling precipitation and thus the clico starts again. With passing of the years, the population comes very increasing of fast form, bringing as consequence a great water consumption. But the lack of awareness and information for the population, makes with that the use irrational of the water is practised by great part of the population.
