Driven to Extraction: Can Sand Mining be Sustainable? by

Sand is a critical ingredient for many of the materials that we take for granted: concrete, glass and asphalt. Sand and coarse aggregates form the backbone of the modern world and also, through land reclamation, the ground on which we live. A growing global population increasingly living in cities has led to a spiralling rise in the extraction of sand and aggregates, with serious environmental
