Environmental Science

The Department of Earth and Environmental Sciences offers undergraduate study leading to a B.S. degree in environmental science. Focused on developing foundational knowledge and a broad set of field and laboratory skills that allow students to seek employment or prepare them for continued academic study in the earth and environmental sciences.

Environmental science is an interdisciplinary field that studies physical, chemical, and biological processes that underpin natural ecosystems and human-influenced systems. While their focus is often on the physical and life sciences, environmental scientists must also be mindful of social issues, political context, economic factors, and human well-being to understand and address environmental problems. The degree reflects this broad, systems-level approach, with coursework in science, mathematics, and social sciences. This allows students to understand the science and social issues involved in addressing complex environmental problems such as environmental contamination, access to food and safe drinking water, and climate change.
