This work is intended to analyze some aspects concerning the recent technological innovations, and their consequence to the ambient. Although there is no social development without economic progress, we cannot conceive the existence of a rightfull Democratic State without the preservation of the ambient. The consolidation of the rights and fundamental warranties is only possible with the concretization of sustained development, today considered as utopic. As a way to mitigate the continuous agressions to the ecosystem, we study how modernity influences the formation of the Risk Society, marked by the existance of serious situations that many times go unperceived, but represent a profound menace for humanity. The modern project seems, today, unpracticable thanks to his own foundations. It is believed that, through the adoption of a postulate of caution, concreted by the caution principle, an important step is given for the control of risks. At present, Brasil is living these questions, due to the necessity to regulate the production and use of genetically modified organisms, also known as transgenic foods. In this case, the normative instrumets that are going to disciplinate the use of the principle of caution in our country may be an important instrument of defense of this democratic conception of the interpretation of ambiental laws, inclusive in the field of democratic hermeneutic.
