Ecological extinguishing of animal and vegetal species, pollution, disasters, ecosystem disequilibrium, heating and climatic changes are test of the unsustainable trajectory of the humanity. Therefore, she is necessary to modify its course. They have been projected scientifically, since the passed century, the real and definitive threats that the economic development exerts against the life in the Land. As well as foreseen the conditions to revert or to become irreversible the ambient damage. also indicated stated periods and steps to follow in development in the sustainable way. Beyond necessary, it is urgent to modify the routes of the development for sustainable The history of the relationship of the man with the environment registers alerts, important manifestations, studies and projections, that prove the predatory character of the activities human beings in the reversible and irreversible planet, its degradantes effect, its secular and physical risks to the preservation of the life and its limits. About three million years behind, man paleolithic discovered as to manipulate fire, however, not imagined that this new form to contaminate air would be the beginning of the beginning of the process of degradation of the environment, that continued with the discovery of agriculture, has ten a thousand years.
The humanity if instituted of the power to dominate and to modify the environment in its process of development, being preferred a predatory and easied model with the consequncias for biodiversity, for the life in the planet. As if they did not depend on the balance of ecosystems and the integrity of the natural diversity for its existence, the human beings have allowed insistently that the economic development dictates the norms of its relations with the environment. In this way, the way of production and consumption explores, exaure, wastes, it does not restitute and not conserve natural resources, polui air, ground and land, and if constitutes as serious threat of generating problems in the whole world.
