Bachelor of Science in Environmental Science
The B.S. in Environmental Science (BSES) is designed to provide a scientific background with both breadth and depth to prepare students for professional science-related employment and for advanced study at the graduate level. Students must complete a set of Foundations, Intensive Writing, Breadth of Inquiry, and Public Oral Communication requirements, a core curriculum, and a field experience requirement.
