Environmental Science Major

The ten-unit environmental science major provides broad exposure to environmental sciences at the introductory level, focused work in science at the upper level and a set of cognates designed to show the social and humanistic context in which scientists work.


  • Core: Five units of science and mathematics, consisting of Biology 195, Chemistry 121, Geology 101, Geology 111 and Mathematics 141.

  • Science electives: Five units of focused work in science. Courses should have a central theme such as (but not limited to) habitat protection, modeling in environmental science, or water resources, and should be selected in consultation with a science faculty adviser and approved by the CSE director. Courses must be at the 200-level or higher, no more than three courses can be in one department, and at least one 300-level course must be included. Before beginning the study of theme, the student must secure the CSE director's approval of the proposed five-course sequence. This approval must be granted no later than mid-semester of the second semester of the student's sophomore year. A copy of the approved program and any subsequently approved changes are to be filed with the registrar after being signed by the CSE director.

  • Cognate courses: Two and one-half units, ENVN 201, ENVN 220, and one additional cognate selected from the "Society and Culture” or "Language, Idea and Image" lists in the environmental studies major.

  • Experiential requirements:

    • Attendance at a series of seminars each semester. In these, students who completed internships the previous semester will report on them, and other items of general interest, such as graduate schools and careers, will be discussed.
    • An environmental research project, service project or internship. Students should have prior approval of the CSE director, and must make a presentation in the seminar and submit a paper summarizing the experience.
