This is an issue-based discussion course that integrates previous learning with the fundamental scientific principles underlying the issue. Discussions will likely include interdisciplinary scientific principles designed to develop issue competency and critical thinking skills. Several topics will be explored from either long-standing or current environmental science issues. Students are expected to conduct extensive research on the topics and communicate their knowledge in both oral and written assignments. Topics may change over time, but the basic focus on the underlying interdisciplinary scientific principles will remain.
