This course is an in-depth study of environmental ethics. Reading widely in classic environmental literature, we begin by interrogating the changing referent of the term 'nature,' from animals and wilderness, to city parks and the organics movement. We then critically compare 1) 'nature' with forms of life that are socially naturalized (e.g. able-bodied people) and 2) anti-nature (e.g. toxic waste) with the so-called socially unnatural (e.g. the queer, the immigrant).
