A timely, powerful look at fifty years of the Clean Air Act and the challenges we still face to ensure healthy air for everyone. Weaves historical milestones with current-day stories of environmental injustice, including a case study of Louisiana's "Cancer Alley" and the role of the oil and gas industry in thwarting clean air standards. Nearly half of all Americans still live in areas with unhealthy levels of air pollution, particularly in poorer and Black communities.
