Environmental Sciences Major

The major in Environmental Sciences has two tracks: one in science (Science Track) and one in economic policy (Policy Track). The tracks share foundation courses in science and math, and the core curriculum. Advanced coursework differs by track.

Students plan their academic paths with an environmental sciences adviser. Many foundation courses are prerequisites for advanced courses and should be completed as soon as possible. Students envisioning graduate training are specifically encouraged to take additional math and/or the General Physics sequence. Students interested in medical professions and environmental biology are advised to take the full 200-level sequence in biological sciences and two additional quarters of organic chemistry.

Students must also complete the Undergraduate Registration Requirement and the degree requirements of their home school.

Major Requirements: Program Courses (11 units)

3 Core Environmental Science Courses at the 200-Level

Course Title
Earth: A Habitable Planet
The Health of the Biosphere
Humans and the Environment

8 Advanced Studies Courses

Advanced studies courses differ by the chosen track. In both the science track and the policy track at least 6 of the required 8 advanced studies courses must be at the 300-level. See the Advanced Studies Course Lists below for lists of approved courses. See the Environmental Sciences webpage for updates to these lists. Students who double-major in economics and environmental sciences are encouraged to do the science track in environmental sciences, and must take extra 300-level economics classes to fulfill the requirements for both majors.

Honors in Environmental Sciences

Students with strong academic records and an interest in pursuing honors should approach a faculty member by the end of junior year to discuss possible projects; these may involve field, experimental, or computational research. Research is completed during a minimum 2 quarters of ENVR_SCI 399-0 Independent Study, which may count toward major requirements. Students then prepare a written thesis. Those whose theses and grades meet program criteria are recommended to the college for graduation with honors. For more information consult the program director and see Honors in the Major.
