What it is	Environmental sciences combines biology, chemistry, economics, and Earth systems to understand how environments work and how human activity affects them. The co-op option lets you alternate between study terms and paid work placements with environmental organizations, government agencies, or companies, giving you real experience alongside your degree. This program suits people who want practical skills in environmental problem-solving and prefer learning through both classroom study and workplace application.	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 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.
