The course examines current environmental issues for which there is no easy answer or consensus position. For instance, to help solve climate change should we generate more electricity from nuclear power-plants, which have no greenhouse gas emissions? Or instead, should we phase out nuclear plants because of possible accidents, costs and radioactive wastes? The seminar examines the scientific and political aspects of such issues and debates the pros and cons of each. Restricted to first-year students. Not eligible for CR/NCR option.
