The critic of necessity is a critical field of political economy, here in this suggested thesis, aimed at an extension of the theoretical conditions in which human and social need has meaning within the capitalist system from the structural analysis of the theory of value . The need, as a historical process of satisfying needs in capitalism is reversed in double character, namely. In the sense that society has no control or autonomy on the possibilities and conditions to meet social needs, this situation caused by the social form of value; also the ideological reversal that puts the social subject in the illusion that it is the master of social relation of the commodity form. As capitalism becomes a production value of social system, absorbing the social totality, a tautology, the capitalist system absolutizes the need for appreciation of value. The commodity-producing society transforms the mode of production in a process of total dependence, the commodity form is, above all, the creation of an empty access material needs satisfaction conditions. The absolute mode of production and dependence on all forms of acquisition and consumption create distance between society and the productive capacity of capitalist society. Since capitalism is, in turn, industrial sociability, the needs of the production process follows the industrial form in all walks of life. Around such a determination, the major problem that is established within the research by reflecting the terms under which capitalism is today arises. These terms mooted the crisis of world capital, as well as site - the premise of this crisis is in the law of value inability to continue to be structural and structural basis on which the system does as capitalism. The production value is plummeting, for the reasons that historically Marxian thought features, namely the value of the structure maintenance breath is collapsing and irrevocably through the historical mode of production contradictions (science, knowledge, technical, technology, dead labor), the basics of capital vanish. It is this structural shakeout scenario that the crisis needs reveals its historical inability to sustain humanity in the face of imminent shutdown of production of goods, since the dependence of the productive forces a state perspective of social barbarism in the world society is layered and the fact that the collapse of the capital system will engender greater social breakdown, deepening the crisis in the various spheres: political, institutional, legal, social, productive, etc., the reality of the need becomes immense charm of conflicts reach-national state, the dead labor, the process of meeting the needs, sociability with its many drawers ideologically organized as an expression of the domination of needs in barbarous state of need. The universal use value becomes a historical mechanism of the productive forces that can provide new access conditions to the needs and requirements systems, bringing down borders and cultural nuances, but not without considering the immense challenge of historical current conditions of the crisis unfolding final of the capital system and its imminent collapse.

The theory of landscape ecology applied to the methods of spatial analysis helps to understand changes in the structure of forest remnants. In view of this theory, the objective of the present study was to analyze the structure of a fragmented area between the years 1979 and 2015 through calculation of landscape metrics for arboreal, shrubby and herbaceous vegetation classes. Vegetation classes were classified with visits to the field, interpretation of aerial photographs from 1979 and supervised classification of Landsat 8 from 2015. The metrics calculated for each class were area and total number of fragments, total edge and average connectivity among the fragments. The analysis of structure found that it changed negatively due to an increase in the number of small fragments, which increased the intensity of edge effects and reduced connectivity between fragments for all classes.
