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.	A BA in Geography covers the physical Earth — landforms, climate, ecosystems — alongside human systems like culture, economics, and cities. You'll study both natural processes and how people shape and live in different places. It suits students curious about why the world works the way it does and interested in solving real-world problems across environment and society.	This is a four-year science degree where you specialize in one of many fields — from chemistry and physics to biology, geology, audiology, linguistics, or environmental science. The honours designation means you go deeper into your chosen subject than a general science degree would. The program includes optional co-op work terms, letting you gain paid professional experience alongside your studies, which suits students who want both classroom learning and real workplace practice in their field.	A Biology degree at Glendon lets you study how living things work, from cells and molecules to whole organisms and ecosystems. You'll take core biology courses and choose from specialized areas like genetics, microbiology, human biology, or biotechnology. The iBSc variant integrates bilingual (English–French) instruction throughout your degree, rather than offering biology taught only in English.
