What it is	Environmental Chemistry is the study of chemical processes that happen in nature and how human activity affects them — from water pollution to atmospheric reactions to soil contamination. Unlike a pure chemistry degree, it combines lab work with environmental science, so you learn both the chemistry itself and why it matters for ecosystems and human health. It suits people who want a science degree but care about real-world environmental problems rather than working only in industrial or research settings.	Environmental Studies is the scientific and social examination of how humans interact with the natural world — covering ecology, climate, conservation, pollution, and policy. This program teaches you both the science behind environmental problems and the social, economic, and political solutions. The co-op option lets you alternate between classroom semesters and paid work terms with environmental organizations, government agencies, or industry, giving you real workplace experience alongside your degree.	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.
