Does the Sustainability of the Anthropocene Technosphere Imply an Existential Risk for Our Species? Thinking with Peter Haff

Throughout the 20th century, several thinkers noticed that Technology was becoming a global phenomenon. More recently, US geologist Peter Haff claimed that a Technosphere is now in place and can be conceived as a new Earth geological system. This unprecedented situation is creating enormous challenges not only for our species, since more and more of its members are now dependent on the subsistence of this man-made sphere, but also for other species and natural ecosystems that have become increasingly dependent on it. Perhaps the most crucial of these challenges is the sustainability of the Technosphere itself. In the first part of the article, I attempted a critical reconstruction of Haff’s Technosphere concept. The second part is dedicated to analyzing how the unsustainability of the Technosphere represents a global catastrophic risk and ultimately an existential risk
