Environmental Science

Saint Louis University's undergraduate major in environmental science will develop your understanding of Earth's natural systems and their interconnections with human society. The program is designed to help you thoroughly understand the geosphere, hydrosphere and biosphere before focusing on sub-disciplines such as human population growth or climate change.

Major in Environmental Science

If you choose to major in environmental science at SLU, you'll have full access to the resources of the University's Department of Earth and Atmospheric Sciences, including excellent computer and research laboratories, departmental field trips and internship opportunities.

Students majoring in the Bachelor of Science program are required to take 14 more credits of science and math, resulting in a firmer grasp of the sciences required. The Bachelor of Arts degree is potentially more appropriate for students interested in pursuing a professional degree in areas such as law or business, or who are more interested in the public policy associated with environmental science.

Environmental science students at SLU can choose from four concentrations: biology, chemistry, atmospheric science or geoscience. The concentration requirements are individually defined by the department and are roughly equivalent to completing a minor in the specific area of interest.

You will also have the option of participating in a capstone project that provides you with a real-world perspective on concepts you learn in class. In addition, you may choose to participate in faculty research projects, many of which include funding specifically to support the participation of undergraduate students.

Real-World Experience

Field Trips Across the U.S.

Weekend field trips, canoe trips and social events are scheduled throughout the year. One perk associated with this major is the opportunity to join other faculty and students on annual, weeklong field trips across the country. Visit environmentally important sites and get to know the faculty, other students and alumni who join the trips.
