To conciliate environment with healthful life becomes inevitable to have the support basic rule that it thinks about current and the future generations. To adentrar in the subject that will be boarded with focus in article 225 of our great letter, it fits to mention the definition of animal, vegetal life and human being, to understand legal the importance ambient of these elements to have an ambient balance. Thus, initially we go to the concepts: 6 – ANIMAL LIFE the fauna and flora are species that if reproduce and transmit its characteristics to its descendants. With the evolution of each species and its strategy of reproduction genetically determined, some species had evolved separately for geologic accidents. The animal species in its majority if put into motion in definitive spaces.
However the migratory species exist that cover enormous distances looking for a place to multiply, looking its habitat. Some species alone if feed of definitive plants or animals and or demand ground with particular characteristics for its procreation. Thus the maintenance of biodiversity is of vital importance. ' ' The biodiversity concept, in accordance with Cesar Benjamim, includes all the products of the organic evolution, in all the levels of genes until complete ecosystems, passing for the organisms vivos.' ' The science that studies the animals is called zoology All and any study that it intends to give to subsidies for the understanding and/or maintenance of the ecological balance in surrounding data it does not do without the knowledge of the organisms compose that it. The animal diversity is very little known in our tropical and tempered regions. The number of still unknown species sobrepuja in very to everything what already we know. Simpson, 1952 (Evolution, 6:342) esteem the existence of 2 million living animal species; Mayr, 1969 (Principles of Systemcatic Zoology, New York) indicated that it would have enters the 5 10 million species; whereas Erwin, 1982 (Coleopterist' s Bulletin, 36 (1): 74-75), supported in studies carried through in the Amazonian forest, esteem that only the insects they would present a diversity of about 30 million species.
