Abstract: This article examines the relationship between mass incarceration and environmental inequalities. The United States incarcerates more people than any other country, and incarceration is highly racialized. The article discusses how prisons are settler colonial ecosystems that produce injustice. Prisons are located close to hazardous sites and in areas prone to extreme weather events. Food insecurity is also commonplace in jails. The article introduces concepts such as carceral food justice and carceral food sovereignty to recognize the unique circumstances that inmates experience in their quest to acquire healthy, affordable, adequate, and culturally desirable food.
