What it is	Environmental Science is the study of how natural systems — including geology, weather patterns, and ecosystems — work and how human activities affect them. You'll take courses across earth science, geography, and environmental studies to understand environmental problems and solutions. The Co-op version requires you to complete paid work terms at environmental organizations or research facilities alongside your studies, giving you real workplace experience in the field.	You study chemistry, physics, astronomy, or geology at an advanced level, choosing your focus after first year. This program includes a co-op option that lets you work for employers in research, industry, or government between school terms. It suits students who are curious about how matter, energy, and natural systems work and want both hands-on lab experience and real-world work placements.
