Construction: limit China's sand mining
“Sand mining in China has been massively stepped up over several decades to make the concrete and cement needed for the country's boom in urbanization infrastructure. The scale of this activity in the Yangtze River basin, for example, has destroyed crucial spawning, feeding and rearing grounds for its aquatic organisms, contributing to the demise of unique species.”
Why there is a shortage of sand
“Sand is in high demand. In some parts of the world, people are going to increasingly great lengths to get their hands on the golden grains. A ‘sand mafia’ in India intimidates locals in order to extract and transport the material.”
Sand mining: the global environmental crisis you’ve probably never heard of
“The global urbanisation boom is devouring colossal amounts of sand – the key ingredient of concrete and asphalt. Shanghai, China’s financial centre, has exploded in the last 20 years. The city has added 7 million new residents since 2000, raising its population to more than 23 million.”
