This chapter argues that breathing is an abolitionist practice: a material, ethical, and rhetorical labor through which communities resist suffocation and cultivate alternative ways of living together. Drawing on Black feminist thought, abolitionist theory, and critical respiratory studies, it examines how racialized respiratory harm—produced through climate coloniality, environmental racism, policing, carcerality, and immigration regimes—reveals the violence of the prevailing world order. Through a case study of Chicago’s #LetUsBreathe Collective, the chapter traces how grassroots abolitionist praxis reworks the cry “I can’t breathe” from an articulation of racialized death and harm into a generative starting point for world-making grounded in mutual aid, healing justice, artistic production, and spiritual care. Methodologically, the chapter advances a praxis-driven rhetorical approach that centers “radical subjects” (Aswad) as theorists in their own right while challenging top-down epistemologies and liberal recuperations of breathing as individualized wellness. It concludes by calling for a critical respiratory studies attuned to abolitionist and revolutionary struggle, where breath is understood not as metaphor alone, but as a radical site of political invention and collective possibility.
