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.	You study how to run and launch businesses while learning environmental science and sustainability principles. This combines business skills with ecological knowledge, so you understand both profit and environmental impact. The co-op requirement means you alternate between classroom and paid work terms, giving you real workplace experience in green business and sustainability roles. It suits people who want to work in business but care about environmental problems.	You study how Earth's physical systems — rocks, soil, water, and climate — interact with living things and human activity. This program combines geology, geography, and environmental science rather than focusing on just one. The co-op option lets you do paid work terms with employers in the environmental or resource sector alongside your coursework, giving you real experience before you graduate. This suits people interested in understanding environmental problems and possibly working in conservation, resource management, or environmental consulting.
