Undergraduate Major

Environmental Science & Sustainability Major (BS)

Engage with and protect the natural world with an environmental science and sustainability degree. Through field work, research experiences, internships, and international travel, you'll become a leader in addressing today's most pressing environmental and sustainability issues.

Environmental Science Hero

Program Overview

Sustainability and environmental well-being are some of the most pressing matters facing society today. You'll think critically, engage creatively, and act empathetically towards the natural world and its inhabitants when you study environmental science.

You'll learn scientific foundations in small classes, working directly with professors dedicated to knowing you personally. Before long, you'll be studying exotic insects in a federally restricted lab and monitoring pollutant levels in local waterways.

You'll also engage in research projects that can take you all over the world, from the coffee farms of Costa Rica to the jungles of the Amazon Basin in Peru. You'll direct your own research projects and constantly be sharing your work in class and on the local, regional, and even national levels.

All these experiences will prepare you to be an engaged global citizen and innovator in the field of environmental science.

Students can obtain secondary certification in Earth and space science by completing the secondary education track. Students must also follow the instructions and requirements in the Center for Education section. Students may seek certification in more than one field; however, this usually requires more than eight semesters. Students who wish to become certified in more than one area should work closely with their faculty advisor when planning course schedules.
