What it is	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.	Environmental Geoscience is the study of Earth's physical systems — rocks, landforms, water, and climate — combined with how human activity affects and depends on the environment. It differs from pure geology because it emphasizes the interactions between natural processes and people, drawing on geography and environmental science alongside earth science. It suits students curious about how landscapes form and change, and interested in solving real-world problems like pollution, resource management, or climate impacts.	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.
