What it is	You study how Earth's physical systems — rocks, soil, water, and climate — interact with living things and human activity. This program combines geology, geography, and environmental science rather than focusing on just one. The co-op option lets you do paid work terms with employers in the environmental or resource sector alongside your coursework, giving you real experience before you graduate. This suits people interested in understanding environmental problems and possibly working in conservation, resource management, or environmental consulting.	You study how the natural world works alongside the human systems that affect it. The BES focuses on environmental policy, conservation, and sustainability through social and geographic lenses, while the BSc emphasizes the physical science side: geology, ecology, and environmental processes. Both paths suit people interested in solving real environmental problems through either policy and community work or scientific research and analysis.	You study physical sciences — chemistry, physics, geology, and environmental topics — with a focus on how they connect to human health and the living world. This stream emphasizes the intersection between earth and life sciences rather than pure physics or chemistry alone. The co-op option lets you do paid work terms at relevant employers alongside your degree. It suits students interested in environmental health, toxicology, or science careers that bridge the natural world and wellness.
