This vision of full fungibilidade mentions the possibility to it of the exchange of ambient goods for economic and social, enclosed conquests there, guarantees to the dignity of the person human being, guarantees politics and generation of job and income. It has a portentoso risk in this approach, the risk of that the goods can be fungible in its completeness, the risk of the exhaustion of the resources under gide of the development. The development is necessary and inexorable, as the liquidation of the social debit is imperious. In this aimed at, the fungibilidade of the resources can accepted if only be watched by the beginning of the prevention and the precaution. As the beginning of the precaution, that is permanently antecipatrio, any action, technique or method that generate ambient risk will have to prosper only after approved for deep inquiry technique that it certifies, with proven scientific security, that the risk is reasonable acceptable. In this manner, the exchange of the environmental resources for the development would demand test absolutely insurance for its efetivao. Not one politics of risk zero advocates this principle, it only demands that the had importance to the protection of the public health and the environment is given whenever the number of available scientific information is insufficient for a taken insurance of decision.
The beginning of the prevention, in this context, he is closely on the beginning of the precaution. Milar engloba the first one in as: ' ' The prevention for its generic character, engloba the precaution for its specific character. The precaution precedes the prevention, therefore its concern is not only to prevent the ambient damage, but over all to prevent the ambient risk. Which is quantum allowed? Which the limit of the exchange? The beginning of the information that it invokes the dissemination of the ambient education will be able to mitigate relative the inevitable risk to quantum fungible. The fungibilidade will be positive will have the support of the scientific knowledge and under incondicionada monitoring permanent of the principles of the precaution and the prevention, and more still, after ample quarrel, participation and vigil accomplish of the organized, informed and compromised community that will have to be capable to negotiate the limits. The social and economic development is necessary, however she is necessary to think very well before tolerating ambient losses, thinking not only about a perspective of centuries and of decades. The risks are many and will be always going up to around the planet. We are all responsible ones for the future generations, therefore, we must act with moderation, prudence and responsibility, in another way, the perspective of the disaster is real and previsible.
