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.	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.	You study how Earth's climate and environment work, using chemistry, physics, and geography to understand weather systems, ecosystems, and human impacts. This program combines natural science with social geography, so you examine both the physical causes of environmental change and how people and communities respond to it. It suits students curious about climate science who want hands-on experience through co-op placements alongside their coursework.
