Latina/o environmental justice literature, prompted by organizing against environmental racism and for ecologically linked social responsibility, emerges in the late 20th century, but environmental justice literary interpretation and critical theory examines texts from any period of Latina/o literature, engaging the nexus of nature, culture, and environmental degradation and justice. Latina/o environmental justice literature includes many genres (fiction, poetry, nonfiction, memoir, testimonio, and performance art, to name a few) and has umbilical connections to a large body of lived experience, longstanding theory and praxis, traditional environmental knowledge (TEK), and environmental justice movement activism. This body of literary poetics that followed the emergence and naming of the environmental justice movement in the 1980s had precursors in the cultural poetics of the civil rights movement and related struggles for justice, equality, nonviolence, feminisms, human rights, and environmental protection. Antecedents to Latina/o environmental justice literature are found in oral literature, pre-Columbian texts, and subsequent Latina/o writing. Definitions of environmental justice within the context of the burgeoning environmental justice movement in the latter decades of the 20th century contribute to interpretations of the literature from this period forward. The last decades of the 20th century and beginning of the 21st century saw environmental justice themes emerge in many genres, and Latina/o literature made significant contributions to the broader field. Studies of cultural poetics of environmental justice contributed to that diversity. Contemporary environmental justice literary scholarship summarizes past approaches, traces ongoing work, and offers future directions—redefining and rebirthing environmental justice and climate justice poetics, given global warming and resulting climate change.
