Nature is the intermediary place between the raw energy of the matter and those superior of the man. It contains, in hidden way, the principles and the rules that move the universe. The environmental education has been seen for too much time as that discipline through which respect and protect the nature. This vision must be reversed: it is instead that culture that derives from the observation of the rules that move and regulate the nature. The environmental education assumes today therefore a new function for a man that must reenter in the only rules that can guarantee the Sustainable Development.
