The Postmodern social constructionist of nature is a theorem of postmodernist continental philosophy that poses an alternative critique of previous mainstream, prometheun dialogue about environmental sustainability and ecopolitics. Whereas traditional criticisms of environmentalism come from the more conservative "right" of politics, leftist critiques of nature pioneered by postmodernist constructionism highlights the need to recognise "the other". The Implicit assumption made by theorists like Wapner refer to it as a new "response to eco-criticism would require critics to acknowledge the ways in which they themselves silence nature and then to respect the sheer otherness of the nonhuman world."
