The Report provides a historical and present-day overview of environmental justice in the U.S.-Mexico Border Region. It reviews how race, poverty, and the international border have affected communities and the management of the shared border environment. It also details the diverse set of specific environmental justice issues, ranging from pollution, toxics, and public health matters to labor justice, immigration, indigenous peoples, and language matters, that were raised by the participants of the International Roundtable. Finally, the Report also draws conclusions and provides proposals for further agency actions that will improve the Agency's response to environmental justice problems. The Report appendices also contain a detailed summary of the proceedings of the International Roundtable on Environmental Justice.
