Despite the recognition by early champions of the environmental movement in the United States that humans and the diverse ecosystems in which they live are indivisible, many environmental education policies and programs have tended to uphold the categorical distinction between "nature" and "culture" (e.g., Sessions; Soule and Press). In the late 1960s, Rachel Carson's "Silent Spring" introduced the concept of "ecological interdependence," conceptualizing humans as part of rather than distinct from nature. Despite this, many environmental studies programs leave it to the individual student to do the work of imagining the interdisciplinary connections. In this essay, the author discusses how to use the feminist concept of "intersectionality" when teaching Urban Ecology, an environmental studies course that strives to put into practice the environmental justice activists' emphasis on the "interdependence" of human health, ecological integrity, and social justice.
