As an environmental science major, you’ll explore the interaction between natural systems and organisms – including humans. With this interdisciplinary major, you’ll delve into a wide range of fields including biology, chemistry, agricultural science, economics, political science, and environmental studies. As you work toward a broad understanding of these various fields, you’ll start making connections and developing insights on how you can tackle challenges facing the environment today.

Career Paths

The environmental science major prepares you for careers related to conservation biology, environmental monitoring, environmental consulting, and many others. You can help protect and manage natural resources, clean up polluted areas, advise policy makers, or work with industry partners to implement environmentally sustainable practices.

Featured Courses

Learn about the interconnectedness of organisms, environment, and evolution by exploring concepts related to population genetics, population ecology, community ecology, macroevolution, physiological ecology, systematics, and functional morphology.
Study the origin, formulation, characteristics, and resultant management implications for use of soil resources, with applications for agriculture, the environment, waste disposal, engineering and society.
Learn about abiotic and biotic components of the Earth’s environment and scientific principles that allow for a fundamental understanding of environmental issues.
Interact with community partners on a project aimed to have a positive impact on the environment in the surrounding community.
Explore the evolution of the environmental movement in the United States; the social and political contexts of environmental policy making; the key institutions, groups, and processes involved in making environmental policy; and the theoretical guidelines employed in environmental decision making.
Study geographic information systems (G.I.S.) and learn how to use a desktop G.I.S. software package to create maps and manipulative data linked to them.
