Understand the deep relations between biology (logic of life, language of life), bioethics (ethos of life) and environment (fruit of the ecosystem-culture relationship, Angel Maya, A. 1996), from the South that we embody, implies decolonizing, deconstructing these three terms from the Southern Environmental Thought. It is about de-anthropizing them and reconfiguring them from geo-thought, that is, the thought that arises from our earth.To see ethics in a telluric way implies to feel it in the earth, as an understanding of the language of nature and of life. Of human life, certainly, but without excluding other forms of life. Rather, it is about denouncing the way in which life is exploited, put at the service of industrial production.Southern Environmental Thought connects bioethics with the environment to show the close aesthetic-complex relationship between these two words. The term Abya Yala reflects this reality. Originally from Cuna, this word means to live well and refers to the way of living of the non-Westernized human. It also means the generous, fertile and flowering Earth, words which evoke the way in which the Habitat allows the inhabitant to poetically inhabit the Earth.Thus are born new ethico-aesthetic epistems: ways of knowing-understanding-recreating, de-westernized, configured from other logics, other ways of feeling, and which show the abyssal gulf between Western thought and Southern thought.
