This is the fourth lesson in the series "Using Editorial Cartoons to Teach Social Justice."People who are poor don’t have access to the kinds of resources—good jobs, high-quality education and health care, for example—that people with more money have. One thing they do have access to, unfortunately, is a disproportionate share of environmental problems. You can see why: People who can afford to, live in places far away from oil wells, factories and toxic waste dumps. People with less money more often live near those environmentally undesirable—and often dangerous—places.
