What it is	Environmental Biology is the study of how living organisms interact with their natural surroundings — plants, animals, ecosystems, and environmental problems like pollution and climate change. The BSc&Mgt option adds business and management courses, preparing you to lead environmental projects or organizations, whereas the straight BSc focuses purely on the science. This program includes co-op work terms, letting you gain field or lab experience while you study. It suits people drawn to solving real environmental challenges and wanting hands-on experience before graduation.	This is a four-year science degree focused on understanding natural systems and how human activity affects them. You study biology, chemistry, ecology, and earth science together rather than picking one specialty. It suits students who want a broad grounding in environmental problem-solving and are comfortable with lab work and field studies.	You study chemistry, physics, astronomy, or geology at an advanced level, choosing your focus after first year. This program includes a co-op option that lets you work for employers in research, industry, or government between school terms. It suits students who are curious about how matter, energy, and natural systems work and want both hands-on lab experience and real-world work placements.
