For those who like me are wondering why folk are sucking sand out of the sea in the first place - the TL;DR bot missed this bit:
"Sand and gravel makes up half of all the materials mined in the world. Globally, 50bn tonnes of sand and gravel are used every year – the equivalent of a wall 27 metres high and 27 metres wide stretching round the equator. It is the key ingredient of concrete and asphalt.
“Our entire society is built on sand, the floor of your building is probably concrete, the glass on the windows, the asphalt on roads is made of sand,” said Peduzzi. “We can’t stop doing it because we need lots of concrete for the green transition, for wind turbines and other things.”"
