Program Description
Environmental scientists use their interdisciplinary knowledge to investigate environmental systems and explore their relationship to our everyday lives. While studying environmental science at CMU you will learn to sample, analyze, model, interpret and predict earth system properties and address environmental problems. At CMU you will gain the knowledge and skills to understand and make a difference in the world around you.
Points of Pride
- CMU's location in the heart of the Great Lakes provides the perfect setting to study the environment, with state-of-the art facilities in Mount Pleasant and at the CMU Biological Station on Beaver Island.
- Fieldwork is a key part of the program’s courses, with multiple field trips to CMU-owned Veit's Woods and Neithercut Woodland to assess properties such as soil and water chemistry, streamflow, and erosion.
- Students in the program have the opportunity to work with state-of-the-art software, field instruments and laboratory equipment that are used in industry, government and academic settings.
Put Your Degree to Work
Employment of environmental scientists and specialists is projected to grow 11 percent through 2026, faster than the national average for all occupations. Program graduates are qualified for employment as environmental technicians, consultants, chemists and regulators. Graduates also may continue on to pursue graduate degrees in the fields of environmental and earth sciences, policy, and law.
