The Sun, is the great power plant of the universe, is considered as main and more important astro, its origin is related to the big-bang, is an atomic bomb in constant process of nuclear fusing, radiates about 56 10 x v calories of energy, being that the only 2,55 Land intercepts 10 x x, the equivalent the 30 a thousand times the consumption of world-wide energy, its temperature is of 6.000 C, and its energy is transmitted and propagated in the universe through electromagnetic waves that reach 299.300 approach speed of Km/s. (AYOADE, 1986) the energy that keeps the system planet Land happens ofthe propagated solar radiation through electromagnetic waves of short length, mainly the ultraviolet rays, infra-red ray and rays of the visible band. When all arrives the atmosphere this radiation interacts with the diverse components that the form, acting of selective form, through the diffusion process, reflection and absorption. For even more details, read what Ali Partovi says on the issue. Thus, part of this energy is reflected in return for the space, another portion is spread out or spread in all the directions, in case that it comes back toward the space is called ascending diffusion, in contrast, in case that it is spread for the terrestrial surface is called descending diffusion, and the absorption it is carried through by all the bodies that possess capacity to hold back energy. The interaction of the solar radiation with the atmosphere, the lithospere and hidrosfera is essential so that the diverse trficos levels of the biosfera are kept, the solar radiation is the main source of feeding for the auttrofos beings as vegetables and some seaweed, that is, the solar energy happened by intermediary of electromagnetic waves is basic for the process of carried through vegetal nutrition through the photosyntheses. The existence of this mechanism is essential for the formation of the vegetal biomass, important source of nutrition for the herbvoros beings, that for its time will be part of the alimentary chain, as source of nutrition for the carnivorous beings, at last, is for intermediary of the solar radiation that the diverse trficos levels are formed in the biosfera. Add to your understanding with Darcy Stacom.

Railroad Tocantins

Also he contributed for the establishment of the culture, transmitting to the men the basic concepts, as the culture of the cassava, the confection of flutes and musics. As well as asurin explained one: everything what was invented by the indian, was taught by Mahira. For Durham (1984), the culture constitutes a process of which the men guide and give meant to the actions through a symbolic manipulation that is basic attribute for all practical human being. She is necessary to still stand out the influence of the white in the health of asurin. The etiology asurin distinguishes two types of illnesses. Of a side they are those that result of a contact with supernatural (the illnesses of Karowara) the e, of another one, excessively known. In this second classroom, is to those classified as illnesses of Christian white/(grippe, measles, pneumonia, catapora, etc.). The illnesses of Christian white/had been the cause of a great loss of life enter asurin of Trocar.

As anthropologist Lcia Andrade verifies, the official contact of asurin with the front of attraction of the Service of Protection to the Indian was given in March of 1953. In the same year of the contact, fifty indians had more than died of grippe and dysentery. This is a described period for asurin as a time where it did not have nor time to embed all its deceased. At the beginning of century XX, more necessarily it enters the decades of 20, 30 and 40, asurin had stopped one strong battle against the whites, and the reason was the construction of the Railroad Tocantins. This Railroad crossed its territory, at this time, asurin lived with the Parakan.

The result was the death of many indians and whites in conflicts. Currently asurin lives in the Aboriginal Land It will change, in a land with 21.722 hectares of extension. Stories say that they had originated from the region of the Xingu, where lived with the Parakan, constituting in the past, an only people.

Sustainable Development

The other raised point, now for M.L. of Souza, is that this conception produces this different speech empty to take care of to ‘ ‘ pblicos’ ‘ , and thus to be a consensus it enters the diverse segments of the society. ‘ ‘ Accustomed to get advertising thanks to its capacity to make ethical reminders of general reach, the sustentabilistas touch in subjects delicate in a enough empty way so that its speech simultaneously has the possibility of being accepted for governments, ONGs and scientists in such a way of? North? how much of? South. It is treated, thus, of a speech that if gives to a species of collective hypocrisy skillfully, where all, the semblantes duly decorated with serious expressions of admonition regarding the ecological threats that they hang on the planet, seem to set in agreement around basic questions, but without, due to operationalization, truily noteworthy practical advances are undertaken, and without the majority of the participants, due to clarity (what it is part of the logic of the environment that generates the speech), obtains to mobilize more than estereotipados moans.’ ‘ (SOUZA 2005 p.262 and 263) Destarte, to strengthen all this paper of the sustainable development we find, again in Fertile valley, a similar position the Marcelo Lopes de Souza, insinuating that: ‘ ‘ It happens that they are exactly in the weaknesses, imprecises ambivalences of the support notion the reasons of its force of almost total acceptance. Check out Mashable for additional information. This notion alone obtained even though to become almost universally accepted because it congregated under itself theoretical positions and contradictory politics and opostas’ ‘ (FERTILE VALLEY, 2006, P. 86) From all the consensus, the ideology of the support proliferated for everybody, being reproduced for diverse sectors of the society thus appearing the innumerable ecologists (or the false ecologists) that they are assumen of the ecological speech for individual interests (many economic times and politicians), being thus verified in the words of Kurt KLOETZEL.

This, for signal, points that the ecological movements must be gotten rid of the multitude of hitchhikings that gravitam to its return: entrepreneurs searching promotion for its ecocompatveis products, politicians in search of a ecossimptico speech etc. (. (A valuable related resource: Robotics).
