[The ecological issue: science and ideology, or the utopia of a time]

Our modern concern over the environment brings us to the historical discussion of Scientific Rationalism, principally in contemporary western society, where the conflict between Man and the Natural World is at its greatest. In an attempt to solve this conflict, Ecology, a field of science, stands out riddled with problems, seeking to draw subjects from other fields into its own. Following an "ecologized world view" (Ecosystemics), some social currents denounce the environmental impact of, technological and industrial models, highly pollutant and dependent on natural resources, generating the contemporary disorder in our biosphere. These movements, following different schools of thought, demand changes in society, taking into consideration the present and future state of the environment.
