ABSTRACT
Ze'ev Naveh, professor of agricultural ecology in the faculty of engineering at the Technion, felt that the scale and intensity of modem technology had brought an unprecedented situation into being. As an ecologist, he expressed concern about the quality of life and pointed out that ecology offered some important ethical elements: the ethics of restriction (control of unlimited growth), the notion of the human technoeconomic subsystem as part of the larger total human ecosystem, and the ethics of the time dimension (i.e., taking responsibility for the consequences of our actions in the distant future).
