What it is	Earth Sciences is a study of rocks, minerals, Earth's structure, and environmental systems — how the planet works and how humans interact with it. The program includes a co-op work placement component, meaning you alternate between classroom study and paid work terms at companies or organizations in geology and environmental fields. It suits students curious about natural systems and interested in learning through hands-on experience in the workplace.	This program combines environmental science, geography, and business thinking to explore how people use and sustain natural resources. Unlike a pure environmental science degree, it emphasizes the economic and entrepreneurial side of solving environmental problems, and includes mandatory work terms where you apply what you learn in real jobs. It suits people who care about the environment but want practical business and policy skills alongside scientific understanding.	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.
