Chronicles from the Environmental Justice Frontline describes four cases in Louisiana in which residents were locked in struggles with industry and government representatives over issues of environmental injustice. Roberts and Toffolon-Weiss explain how, at the end of the twentieth century, situations of environmental injustice were created and eventually resolved. The authors show that conflicts do not occur in a vacuum. Rather, one struggle changes policy, trains political actors, activists, and industry representatives, and can have a significant effect on all future struggles.
