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.	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.
