What it is	Chemical biology combines chemistry and biology to study how molecules work inside living things — particularly how drugs and other chemical compounds interact with cells and organisms. The BSc&Mgt option adds business and management courses alongside the science, useful if you're interested in the commercial or leadership side of biotech companies. This program suits you if you enjoy both chemistry and biology equally and want to understand life processes at the molecular level, or if you're considering roles beyond pure research.	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.	This program combines the study of how cities and human communities interact with natural systems, drawing on environmental science, geography, and social perspectives. You'll examine urban planning, resource use, climate impacts, and sustainability solutions across both natural and human dimensions. The co-op option lets you work in government, nonprofits, or consulting firms while you study, which suits people who want practical experience alongside classroom learning.
