Everyday life and the fabric of modern civilisation depend on using the Earth’s physical resources. This album explores the occurrence, availability, exploitation and sustainability of rocks and minerals. The two video tracks feature Thrislington and Divithill quarries in the north of England. Quarry and road construction managers talk about extraction and road laying processes, bulk aggregate transportation and ways to limit the impact of quarries on their surroundings. This material forms part of the course S278 Earth's physical resources: origin, use and environmental impact.
