"A United Nations report calls for urgent action to avert a "sand crisis" —
including a ban on beach extraction — as demand surges to 50 billion tonnes a
year amid population growth and urbanisation.
Sand is the most-exploited natural resource in the world after water, but its
use is largely ungoverned, meaning we are consuming it faster than it can be
replaced by geological processes that take hundreds of thousands of years, a UN
Environment Programme (UNEP) report says.
Global consumption for use in glass, concrete and construction materials has
tripled over two decades, to reach 50 billion tonnes a year — or about 17
kilograms per person each day — it said, harming rivers and coastlines and even
wiping out small islands."
