What it is	Environmental Sciences is a degree combining biology, geology, chemistry, and geography to understand how natural systems work and respond to human activity. The co-op version requires you to complete paid work terms at environmental organizations or research facilities alongside your studies, giving you real-world experience before you graduate. It suits students who want hands-on learning and prefer to test career directions in the field rather than only in classrooms.	This is a broad science degree where you choose from fields like biology, chemistry, physics, computer science, geology, and others. You take foundational science courses in first year, then specialize by selecting which science subjects to focus on. Co-op is available, letting you do paid work terms at science-related employers alongside your studies.
