Environmental Ecology
This first concern is focuses on the natural environment, so that it does not suffer excessive disfiguration, with quality of life and with the preservation of species threatened with extinction. It sees nature as outside of the human being and society. It searches for new technologies and less pollutants, giving highest priority to technical solutions. This concern is important because it seeks to correct the voraciousness of world industrialism, which always implies high ecological costs.
