Addressing them requires more than awareness. It will require people who understand how environmental systems work, and who can translate scientific evidence into real-world solutions.\nThe Second Major in Environmental Science for Sustainability (ESS) prepares students to do exactly that. Through environmental science, geospatial technologies, field and laboratory research, and interdisciplinary learning, students develop the knowledge and practical skills to drive sustainability solutions and make a meaningful impact in an increasingly complex world.\n\t\t\t\t\t\t\t\t\t\t<h4 tabindex=\"0\">Why This Major?<\/h4>\n\t\t\t\t\t<p><strong>Build scientific expertise: <\/strong>Understand the science behind climate change, ecosystems, pollution, and biodiversity, to develop the knowledge needed to solve complex environmental challenges.<\/p>\n<p><strong>Learn the tools that drive sustainability: <\/strong>Develop practical skills in the technologies increasingly shaping environmental decision-making: GIS, remote sensing, environmental modelling, field investigation, laboratory techniques, and environmental data science.<\/p>\n<p><strong>Turn science into real-world impact: <\/strong>Apply scientific evidence to conservation, climate adaptation, natural resource management, environmental assessment, and sustainability planning through fieldwork, internships, and applied research.<\/p>\n<p><strong>Complement your primary discipline: <\/strong>Whether you study Science, Engineering, Computing, Business, or the Humanities, ESS gives you the environmental science expertise needed to contribute meaningfully to sustainability challenges across multiple sectors.<\/p>\n\t\t\t\t\t\t\t\t\t\t<h4 tabindex=\"0\">Possible Career Pathways<\/h4>\n\t\t\t\t\t<p><strong>Public Sector &amp;
