The environmental biology major provides a broad background in biology with a focus on how organisms interact with environments.

1. Seven departmental units:
   1. One organismal biology course chosen from Biology 110, 111, 121, 152, 172, or 208.
   2. One experimental design and statistical analysis course: Biology 247.
   3. One molecular-to-cellular level course: Biology 289.
   4. One population-to-ecosystem level biology course chosen from 210, 217, 275 (in consultation with advisor, when topic is appropriate), 365, 372, or 375 (in consultation with advisor, when topic is appropriate).
   5. Two additional units of biology courses numbered 200 or above.
   6. Capstone: one additional unit of biology with the CP designation.
2. Four supporting units:
   1. One unit chosen from Chemistry 117, 150, 220, or 230.
   2. One additional unit chosen from courses in chemistry, computer science, geology, mathematics, or physics.
   3. Two additional units with the Environmental Studies prefix (ENVS), Journalism 225 (when topic is environmental writing), or Political Science 255.
3. Students majoring in environmental biology may choose to receive the Bachelor of Science degree rather than the Bachelor of Arts degree by completing a minimum of 4 units in chemistry, computer science, geology, mathematics, and/or physics.
