Definition from EASLCE
"Ecocriticism is the youngest of the revisionist movements that have swept the humanities over the past few decades. It was only in the 1990s that it began to gain momentum, first in the US and in the UK, as more and more literary scholars began to ask what their field has to contribute to our understanding of the unfolding environmental crisis. Initially focused on the reappraisal of Romanticism (as the moment in Western cultural history when still reigning conceptions of nature were formed) and its cultural progeny, it has since broadened to address the question, in all of its dimensions, how can cultures construct and are in turn constructed by the non-human world."
