The ENVIRONMENT AND ITS TRANSVERSALIDADE WITH THEMATIC OF HUMAN RIGHTS the vision of the planet Land of the space stimulated world-wide the ambientalista movement, in reason of the phrase of the American astronaut Neil Armstrong who, resumidamente, described our Gaia as fragile and defenseless. Per many years the common citizen did not apercebeu itself of this fragility, exactly our planet has age esteem around 4,6 billion years, an approach mass of 6 quintilhes of tons, a surface of approximately 510 million Km2 and a diameter, in the line of the Equator, of 12.756 km. Such characteristics, in them he did not seem to be so fragile. This fragility was, acertadamente, in the rejected opinion of some and for others, pointed for English chemistry James Lovelock and the biologist Lynn Margulis in the theory of Gaia (1972). They had affirmed that the Land had to be considered an alive and sistmico organism, that answers to some stimulatons and evolves organisms together with livings creature and not-livings creature.

The Land only produces its proper food, fixes nitrogen in air, fertiliza the ground and shelters a species infinity. These scientists had affirmed that the land possesss a proper and perfect identity. Spurs has firm opinions on the matter. is not for less. Venus, for example, has a dense atmosphere in Co2, what it raises the temperature about 400 C. Mars, in turn, has fine Co2 layer, what it takes low the temperature, about 53 C negative. It is a frozen desert. The Land is a stimulaton the life.

Unhappyly our Gaia comes being degraded year the year, as presented studies in recent years. Some arrive to affirm that if the ambient degradation to continue in the current rhythm, the life, in the end of century XXI, in function of the effect greenhouse, will only be possible in the Arctic, where the temperatures would be bearable for the man. Chistopher Stone, in 1993, said that ' ' the land has cancer and this cancer is homem' '.

1 INTRODUCTION the ground is not constituted only of particle remaining portion of rocks, but also of remaining portions of plants and animals. The particles of the rocks are the mineral components and the remaining portions of plants and animals are the organic components. The present work has the intention synthetically to show to the definition of organic substance as well as its importance for the balance and fertility of the ground. Inside of this context, it is discoursed on the humificao processes and mineralizao, later becomes one brief communication the use of the organic substance in sustainable agriculture and conclusive they emphasize it importance of its diverse papers in the use and the conservation of the ground. 2 DEFINITION OF ORGANIC SUBSTANCE the organic substance of the ground is composed for the remaining portion of plants and animals. The USA organic word because one mentions the remaining portions to it of organisms, and these in turn are formed mainly by organic composites between which it has four great groups.

The carboidratos and proteins are most important, as much one as the other possesss a fast decomposition, contributing for the nutrients of the ground, as nitrogen (n), match (p) and sulphur (s). Another one is the lignina, a highly resistant composition, that persists in the ground being part of hmus. Finally, we have the lipdios (added with waxes and resins), that also they are component resistant and they contribute with sulphur (s) and match (p) for the ground (GUCHERT, ROUSSENQ GRANDSON, 2007, P. 23). Therefore we can define all material organic substance as of organic origin in high state of decomposition. 3 the IMPORTANCE OF the ORGANIC SUBSTANCE OF the GROUND the presence of organic substance is basic for the maintenance of the micron and mesobiota of the ground, therefore the action of the decompositores on this substance goes to return to the ground the necessary nutrients so that the beings livings creature that inhabit the ground can acquire energy to survive and also to keep the balance and the conservation of the ground.

Rains occur throughout the entire year; Absence of dry station (action of the oceanic tropical air masses and of rains frontals provoked for the advances of the polar front). CLIMATE SEMI-RIDO: It possesss temperature raised with low atmospheric humidity, characteristic: Tempering latitudes (it dominates interior, isolated lands of the action of the oceanic air masses for the mountainous mountain range presence); Low precipitations: between 250 and 500 mm annual ones. The half-barren climate is present in Brazil in the regions Northeast and Southeastern. Gain insight and clarity with Ben Bretzman. It is the more populous half-barren region of the world, with 36 million people. COLD CLIMATE: it appears in the bordering band of the tempering zone (North America and Eursia), with negative temperatures for the fact of the longer and rigorous winter to be. The summer occurs in a short period and of amena form: Precipitations reduced in function of low the evaporation; Raised annual thermal amplitude (sazonais differences in the intensity of the insolation). POLAR or GLACIAL CLIMATE: it dominates the high latitudes, with temperatures below-freezing constant.

The winter is long, the dry and very short summer. Similar characteristics to the ones of the cold climate, in bigger point; They are regions of intense winds and that they are covered of ice snow during all the year, with exception of the littoral bands where a tundra vegetation appears during curtssimo summer. In the winter he has days where the Sun is not born, and certain days in the summer it does not set. (Midnight Sun)? Frozen winters elapse of the absence of insolation of the long polar nights. Being that in the Antartic the winter is total inhospitable. COLD MOUNTAIN CLIMATE HIGH: raised altitudes, being its changeable temperature in accordance with the altitude, that is, how much bigger the lesser altitude is the temperature. Exactly in tropical regions, the mountain climate is predominant in this relief.
