The Environment – a SERIOUS WORLD-WIDE CONCERN (the desertificao of lands) In the world exists ten deserts of extensive areas, however, these wild places have thousand of years, exhibited fertile lands, with forests and rivers and, obviously, had living beings. With inexorable passing of the time, of natural form, possibly had to the climate if to become drier, low rain precipitation, a hot region with ground arose half-barren or barren. With almost no vegetation, sand, dry, hot climate, without water, conditions of survival of the human being, exception of some animals that if adaptam to this new ecosystem. The originary term of Latin ' ' desertere' ' meaning abandonment, abandoned, surrounding hostile to the man. Desertificao is the process of ambient or climatic modification that leads to the formation of a barren landscape or a desert properly said.

(Dic. . Houaiss). We see then that the existing deserts had had its origin with the time and of form natural, in contrast of what he is occurring now, where the man is the main causer of this possible transformation. We have in Brazil, fertile, propitious considered land regions to the plantation of almost all the species of plants, however, areas northeast and South of Par seriously they are threatened of being transformed into deserts has long or average stated period, therefore currently they present a half-barren climate In the South of the Country, in Alegrete, increases known ' ' desert of pampas' ' , visible in the ASDs (Susceptible Areas to the Desertificao). The process of deforestation without limits, of uncontrollable form, with the target to remove wood, formation of pastures, culture of the sugar sugar cane, soy and other cultures, wrong behaviors of the man in the use of the ground, only generates improlferos effect. Manifest the degradation of the land, that is, consuming or exhaustion and gradual decomposition of the ground, harming biodiversity, which had not consentaneidade to the normal use of the land. The greed in the activities of mining, with the objective of precious metal extration, for in such a way, digging and dislocating the land without no positive planning. The forest fires are harmful to the environment, mainly in the period of the droughts, promoted for the canavieiros, aiming at cleanness of the sugar cane for the cut. The arsons and guilty devastam extensive areas of native and preserved forests. We are living deeply in the daily one, climatic changes of disordered form, long periods of dries, where the scarcity of rain cause many upheavals to the Brazilians, due to water lack. You will have preoccupying, currently we feel the consequncias of this recklessness, however, if the governmental bodies, not to take urgent and rigorous steps how much to the subject, rigid norms the respect, launching campaigns of orientation to the population in this direction, prioritizing for the prudence, who will suffer are our children and grandsons, therefore in a future not very distant, we will have a desolating picture, the new outbreak of many desert-like areas in Brazil.
