The man-nature relationship has been construed in different ways in different cultures but over time there has been a progressive accentuation of the anthropocentric vision. The possible causes of this cultural process are considered, with particular reference to technological capabilities, as well as its implications.
A brief review of the theoretical models and of the measures used to study the man-nature relationship leads to the conclusion that the very division between man and nature is a limit to an ecosystemic vision, more functional both on a theoretical level (models) and at a operational (interventions to maintain environmental balance).
