n. The interdisciplinary study of literature and ecology.
Wikipedia
Ecocriticism is the study of literature and the environment from an interdisciplinary point of view, where literature scholars analyze texts that illustrate environmental concerns and examine the various ways literature treats the subject of nature. Some ecocritics brainstorm possible solutions for the correction of the contemporary environmental situation, though not all ecocritics agree on the purpose, methodology, or scope of ecocriticism. In the United States, ecocriticism is often associated with the Association for the Study of Literature and Environment (ASLE), which hosts biennial meetings for scholars who deal with environmental matters in literature. ASLE publishes a journal—Interdisciplinary Studies in Literature and Environment (ISLE)—in which current international scholarship can be found.
Ecocriticism is an intentionally broad approach that is known by a number of other designations, including "green (cultural) studies", " ecopoetics", and "environmental literary criticism" and is often informed by other fields such as ecology, sustainable design, biopolitics, environmental history, environmentalism, and social ecology, among others.
