What it is	Environmental Science combines the study of living systems and Earth's physical processes — like climate, water, and soil — to understand how natural environments work and respond to human activity. Unlike a program focused only on biology or only on geology, this degree integrates both to tackle real-world environmental problems. It suits students interested in conservation, resource management, or environmental consulting who want a broad scientific foundation rather than specialization in a single discipline.	This is a four-year science degree focused on understanding natural systems and how human activity affects them. You study biology, chemistry, ecology, and earth science together rather than picking one specialty. It suits students who want a broad grounding in environmental problem-solving and are comfortable with lab work and field studies.	Environmental Science is the study of how living things, ecosystems, and physical systems like weather and geology interact with human activity. You'll combine biology, chemistry, geography, and environmental policy to understand problems like pollution, climate change, and resource management. The co-op option lets you do paid work terms at environmental organizations or agencies alongside your studies, giving you real workplace experience before you graduate.
