Planet Earth: Understanding and Protecting our Environment
Learn Earth systems and practical environmental management
This concise online course from the University of Leeds guides learners through Earth’s interconnected systems — the hydrosphere, biosphere, and geosphere — and examines how human activity and climate change alter water cycles, soils, ecosystems and ice masses. Through case studies on flood management, coastal protection, glacier recession and invasive species, learners see how scientists monitor change and propose practical responses.
The curriculum blends short videos, readings and practical activities to emphasise environmental monitoring, critical zone observatories and applied management techniques, with opportunities to practice interpreting environmental data. Learners can expect to build measurable skills in assessing human impacts, comparing protection strategies and exploring academic or community-focused pathways in environmental science and conservation.
