Harm in the Water, funded by the National Science Foundation as part of the BlueGap Award, examines the history and legacy of water pollution in Black communities along the Mississippi River. The film’s focus is on fertilizer, pesticides, and other toxic pollution, foregrounded by the history of colonialism, plantation slavery, and agribusiness' long lasting negative impacts on Black communities and our environments. The documentary also draws a clear connection between plantation slavery and the chemical plants that are along the river. Along the way, we meet farmers, scientists, community activists, religious leaders, and scholars, who work on environmental justice issues and see the problem of water pollution as an abuse of human rights.
