One million lorries of sand a day are being extracted from the world’s oceans, posing a “significant” threat to marine life and coastal communities, according to the United Nations Environment Programme (UNEP).
The rate of extraction is growing globally and is approaching the natural rate of replenishment of 10bn to 16bn tonnes of sand flowing into the sea from rivers and needed to maintain coastal structure and ecosystems.
