This chapter introduces the idea that social work must prepare not only for climate impacts, but for the possibility of societal collapse. As global temperatures rise, the risk is not just more disasters, but the gradual breakdown of the systems social work depends on: housing, electricity, health care, food supply, communications and safety. Building on the concept of collapsed social work, the chapter treats collapse not as a single apocalyptic event, but as an ongoing condition in which institutions weaken, services fragment, and people are forced to rely on each other to survive. The chapter challenges the assumption that society will always “recover.” Instead, it explores how social workers can continue to act, formally or informally, when the profession itself is under strain or no longer funded in its current form.
