The environmental challenges facing the world today are urgent and complex. A variety of approaches have been enacted or proposed to address these problems, ranging from practical efforts to organize for justice to conceptual attempts to shift how we view our world. All of these approaches have particular strengths and weaknesses, and all raise important questions. The purpose of this introductory seminar is to survey ethical to environmental problems and to examine the central moral questions such problems raise. We will cover traditional, "mainstream" environmental ethical responses as well as more recent alternatives to and criticisms of those responses. Discussion will include concrete case studies as well as theoretical foundations, and the final essay will seek to place the theories in the context of concrete environmental problems.
