ABSTRACT
The objective of this chapter is to set up the purpose of our inquiry about the environmental question: to voice a concern, draw the lines of inquiry, and establish the controversial points to question the consequences of the history of metaphysics, and of Heidegger's philosophical thinking on the degradation of life in the planet; and to think the environmental question from within the conditions for life in order to open pathways toward the sustainability of life in the planet, granting consistency to a thought that is able to inscribe itself within the immanence of life. The environmental question confronts the thought of Being with the conditions for life. It brings up the enigmatic event of the emergence of the Symbolic Order from that of the Real of Life—from the Chaos of the Universe to the Order of Life on Earth—that enabled the reflection on Being in the birth of Greek philosophy, and that throughout the history of metaphysics has intervened in the creative evolution of life, the modes of Being in the World and the degradation of life in the planet, raising the critical question of the crossroads of life on the pathways of thought and the call of the environmental crisis to rethink the conditions for life within the Immanence of Life.
