Socialists have historically thought a lot about the catastrophic risks society faces. Today many DSA chapters have gotten involved in mutual aid to respond to the Covid crisis, generating a debate about how mutual aid fits into socialist work. One form of community engagement that is likely to be increasingly necessary, and is an opportunity for radicalizing angry neighbors, is disaster preparedness. While the prepper subculture is perceived as right-wing, and parts are tied into the militia movement, there are also opportunities for progressive organizations to work with FEMA and local governments. This essay discusses distinctive socialist perspectives on disasters past and future and gives examples of strategic ways socialists can help build disaster-resilient communities.
