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.	Water Science combines biology, chemistry, physics, and geography to study how water systems work and how to protect them. You'll examine lakes, rivers, and groundwater from ecological and physical angles rather than focusing only on engineering solutions. This program suits students interested in environmental problems who want a science-based approach grounded in both living systems and earth processes.	Social Sciences is the study of how people, societies, and economies work. You choose from nine subject areas including anthropology, economics, history, law, geography, politics, and sociology, and can combine them however you want rather than following one fixed path. This program suits students curious about human behaviour, institutions, and the world around them who want flexibility to explore multiple disciplines before specializing.
