Environmental Sciences

Life is sustained by complex interactions between the biosphere, geosphere, hydrosphere and atmosphere. These reactions occur in a thin veneer at the earth's surface that encompasses the lower atmosphere, terrestrial and aquatic biota, soils, sediments and surface and ground waters. This veneer provides our food supply, our drinking water, the air we breathe and, at the same time, acts as the depository of our wastes. In the Environmental Sciences major, you will learn about the scientific principles underlying the major chemical, physical and biological processes occurring at the earth's surface; the environmental impact of these processes and the effects of human intervention on these processes. This program is offered and administered by the School of Environmental Sciences.

A co-op option is available for students studying in the Environmental Sciences major. Students are required to complete three co-op work terms as part of this five-year degree. Working with Co-operative Education and Career Services, students receive support in applying for positions and completing work terms. The co-op experience improves students’ job search skills, work performance and networking abilities, while they explore career opportunities and make money. Learn more about co-op here.

Head shot of Jamie.

"I really like the diversity of classes that are offered. You can take classes covering a wide range of subject areas, or you could narrow in and specialize on one topic. The small size of our program is also nice since it creates a really tight-knit community between all of the students, while also allowing you to get to know your professors on a more personal basis."-Jamie Bauman, environmental sciences (co-op) student
