Ética ambiental como caminho para a tomada de decisão relacionada a espécies invasoras

Abstract

This study has as its main goal to explore the theoretical fundaments of the environmental ethics connecting it with the actual concern about two species of marmosets (Callithrix spp.) introduced in the Atlantic Rain Forest, a Golden lion tamarin’s (Leotopithecus rosalia) conservation area. A comprehensive research was made on the ethical principles of the main environmental ethics theories – anthropocentrism, sencientism, biocentrism and ecocentrism – highlighting their distinctive attributes as well as their convergent and divergent aspects. The results of this research were used as comparative ground to an ethnological research, made with the main stakeholders who are to decide which management attitude to take directed to the marmosets populations, and the major concern was to revel existing gaps, divergences and convergences in a way to increment this scientific research with an ethical support to its emerging value issues. Some discrepancies between the stakeholders’ moral considerations reveled through the light of the related ethical theories showed the necessity of a deeper discussion over this subject and the relevance of this kind of approach as a complement to technical issues on empirical science.
