Pollution Of Waters

When looking in our return, we come across in them with a complex imensido that we call Nature. Speaking candidly Mikkel Svane told us the story. We, human beings, must very be grateful it for having in the great awarded one with the responsible one for our survival, day after day, the Water. The Water has covered 75% of the planet Land and is essential to the life of the diverse existing beings, as the animals, the bacteria, the plants, among others. However, although the undisputed necessity that we have of it, the human being is main the responsible one for its degradation, therefore, through the pollution which is displayed, its use if becomes improper. The waters of rivers, seas and oceans suffer to constants discharges from come pollutants, mainly, of the bad human use, industries and the draining of the water of rains, that brings toxic and organic substances, harming its useful life and the life of its dependents. The Pollution For Bad Human Use is more common in poor localities, therefore, as it does not have sanitation, it is in the rivers where the population it launches garbage of all species and its excrementos. The Pollution For Industrial Residues involves treated and developed substances chemically, being thus, more difficult the treatment of cleanness and demanding techniques more sophisticated to treat and also to control the set free chorume in the processes. The Pollution For Agricultural Contamination is very common in the regions where the farming one more is used, therefore it is caused by the draining of the used agrotxico, through the water of rain, sending great amount of toxic substances to the rivers. Moreover, this draining takes esterco of the animals of pastures and the seasonings, causing the process of the Eutrofizao that is the increase of the number of nutrients and of decompositoras bacteria that consume the oxygen and diminish its concentration in the water, beyond leaving the muddy water for the seaweed, producing gases that, in bigger amount, become toxic.


If the areas in expansion if find in more remote points of the territory, relatively distant of the areas metropolitans and the great urban centers, trend will be the formation of other areas that will pass if to consolidate, until reaching the saturation level, evidenced in other regions metropolitans and other great urban centers, starting to provoke those same phenomena that if find generalized by the whole world, and that they are considered ' ' clssicos' ' in the present time. In any way, either through the concentration in consolidated areas, either through the expansion of new areas, the observed trends historically, in the whole world, are of extreme concentration of people and productive activities in reduced spaces, that they are extended to the expenseses of the natural areas (or dedicated dantes to the farming activities, of mineral extration or forest exploration) and in detriment of lesser urban areas, and mainly, in detriment of the joint and integration of these last ones, between itself, and the great urban areas and regions metropolitans, with cited consequentes malaise previously, felt for the citizens. Exactly thus, the execution of the actions of integration and joint enter the urban centers of diverse sizes between itself and between the great urban areas and metropolitans it must be led to the handle with caution, not to configure a process of territorial occupation that produces situations that they provoke what it is seen and felt as that malaise, that the majority of the citizens the sectorial causes attribute. 5. WHAT IT MUST BE MADE? POINT OF VIEW TECHNICIAN 5,1 CONSOLIDATED AREAS consolidated Areas, as the described ones above, demand actions that depend on its respective profiles, to surpass the malaise felt for the citizens as being of sectorial origin, but that it results of processes of occupation and territorial use. 5.1.1? Actions of control and space rationalization These actions are proper for consolidated areas characterized for highly diversified a productive structure, with a propensity for high levels of incomes and with a trend of continued growth of the same ones.

The Sped

The importance of the reutilizao and recycling of the urban garbage is the subject of this article, that has as objective to explain the reasons of the exaggerated volume of solid residues and humid of the urban cities that are launched outside every day and if not to give to these residues a correct destination they will bring many damages to the population, being that the viable alternative mai is the construction of sanitary aterros. These residues are called garbage, which is resulted of the activity human being growing each time more with the advance of industrialization and the increasing consumption of dismissable products. When liquid, these when solid residues constitute the sewer and, the garbage. As much the sewer how much the solid garbage can have domiciliary or industrial origin. Industrialization, the consumption and the garbage are questions that are closely on, therefore all industrial production have as objective the consumption that, exactly without wanting causes some moment the discarding and the transformation of the substance in garbage. The disordered superexploration of the natural resources comes causing the exhaustion of the same ones, increasing consumption and wastefulness opposes the practical ones of development of a sustainable society. The lack of destination adjusted for the residues is a serious problem in Brazil. With this she is necessary to remake our way of living, to produce, to consume and to discard, that is, to remake our model of development that we construct with the advance of the technology. Being that any initiative in this direction will have to absorb, to practise and to divulge the concepts complementary of reduction, reutilizao and recycling. The level of exhaustion of the natural resources of the present time is caused by the sped up process of production and the technology. For this reason the great industries produce a volume each bigger time of materials, increasing its amount and getting worse the quality of the garbage, with this, adding a infinity of products and raw materials to it that take hundreds or thousand of years to be degraded in the environment.
