What it is	Environmental Sciences is a degree combining biology, geology, chemistry, and geography to understand how natural systems work and respond to human activity. The co-op version requires you to complete paid work terms at environmental organizations or research facilities alongside your studies, giving you real-world experience before you graduate. It suits students who want hands-on learning and prefer to test career directions in the field rather than only in classrooms.	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.
