"50bn Tonnes Of Sand And Gravel Extracted Each Year, Finds UN Study" [1]
"Calls for international standard on extraction and better monitoring of most-exploited resource after water"
"Humans extract 50bn tonnes of sand and gravel every year, according to UN research, enough to build a wall 27 metres high by 27 metres wide around the planet.
Sand is the most-exploited resource after water. But unlike water, it is not recognised as a key strategic resource by governments and industry, something, the UN says, that must change and fast.
The UN report makes the case for greater monitoring of extraction and supply chains, measures to compensate for the associated loss of animal and plant species as well as the uneven social and economic impacts of sand mining.
Given the extent and growing awareness of human reliance on sand for economic development in industries, ranging from construction to IT manufacturing and a number of other booming sectors, the researchers said a fundamental shift in the understanding and valuation of sand was urgently needed."
