Environmental Sciences

AS Degree Environmental Sciences and Sustainability · Sierra College · 2025-2026 Catalog

Successful completion of the Environmental Sciences curriculum will prepare students for transfer to four-year colleges or universities in areas including environmental studies and sciences, wildlife conservation biology, ecology, forestry, toxicology, waste management, and others. Environmental Sciences is the combination of biological, chemical, geological, and mathematical principles as they apply to the environment and environmental problems. Commonly, environmental science is thought of as the study of solving these problems, such as degradation and pollution of the environment, that may have been caused by humans. Environmental science also focuses on preserving and managing natural resources. The major has been designed to meet lower-division requirements for Environmental Sciences majors at transfer institutions.  In all cases, students should consult with a counselor for more information on university admission and transfer requirements. Students must fulfill the following major requirements with grades of “C” or better, complete a minimum of 60 degree-applicable semester units (12 of which must be completed at Sierra College) with a grade point average of at least 2.0 and complete one of the following three general education patterns:
