As the environmental crisis has worsened in recent decades, hundreds of American poets have addressed it in their writing, bringing attentiveness, precision, and tenderness toward existence to bear against the failure of the imagination that has led us to the brink of environmental catastrophe. This essay cannot begin to do justice to the plenitude and variety of contemporary, politically engaged ecopoetry; instead, I will focus on three major poets writing in this vein: Camille Dungy, Brenda Hillman, and Craig Santos Perez. They and their work are quite different from each other. Yet all three are environmental activists for whom poetry is not separate from political engagement and awareness of the ways in which colonialism, postcolonialism, and industrialism have exploited both humans and nature.
