Although the Natural Resources Defense Council (NRDC) is primarily an activist group, the resources available on this page constitute an excellent introduction to the field of environmental justice. Put simply, environmental justice seeks to defend poor communities from the sorts of environmental toxins to which they have traditionally been subjected because of their inability to legally defend themselves. Readers may explore the issues of Global Warming, Energy, Air, Water, Oceans, and Health on this website, and scout such topics as U.S. Law & Policy, Urban Solutions, International Issues, and Transportation. For readers who are looking for an online primer on the topic environmental justice, this site for the NRDC will be a welcome resource.
