Decouple is a show which is fundamentally about attitudes to technology and the role that decoupling technologies, so called technofixes, can play in mitigating and solving our environmental challenges. As we are becoming increasingly aware, geology and its earth systems have not just shaped us, we are shaping the earth through our technologies and indeed our most current geologic epoch, the anthropocene, bears our name as a result. In this episode we dive deep into geologic determinism and a history of technology made more entertaining by the thought experiment of exploring how to rebuild civilization after a global cataclysm with astrobiologist and polymath, Lewis Dartnell who is the author of the books "Origins" and "The Knowledge."
