The World Is Running Out of River Sand, And That's a Massive Issue. Study reveals that the global demand for river sand and gravel to create construction materials like concrete is unsustainable. Read Full Article #SandCrises #SustainableConstruction #…
🌍 Industrial sand mining is depleting river sand globally at rates far exceeding Earth's natural replenishment, making the demand unsustainable according to a review of 411 studies since 1974.
🏗️ In Vietnam's Mekong Delta, sand extraction is 11.8 times the natural sediment replacement rate, causing significant riverbed erosion and leading to over 1,800 house collapses between 2018-2020. Experts warn of no sand left by 2035 if current rates continue.
🏞️ This global issue affects rivers like China's Poyang Lake, India's Mayurakshi, and Brazil's Paraná and Tocantins, impacting water flow, river health, and bank stability.
