(Offered as HIST 26 [C] and ENST 20.) This course considers the ways that people in various parts of the world thought about and acted upon nature during the nineteenth century. We look historically at issues that continue to have relevance today, including: invasive species, deforestation, soil-nitrogen availability, water use, desertification, and air pollution. Themes include: the relationship of nineteenth-century colonialism and environmental degradation, gender and environmental change, the racial dimensions of ecological issues, and the spatial aspects of human interactions with nature. We will take at least one field trip. In addition, we will watch three films that approach nineteenth-century environmental issues from different vantage points. Two class meetings per week.
