Is the world’s sand shortage getting worse?: The world may be heading towards a sand shortage Scientists warn, a global issue is predicted to intensify by the manufacture and rollout of Covid-19 vaccines.
After water, sandGreen trains for Piccadilly line unveiled by TfL is considered the most consumed raw material.
When mixed with bitumen, when paired with cement it becomes concrete and when heated it becomes glass.
Sand is used for the production of the vaccine glass vials, because of these properties.
The world extracts more than 40 billion tonnes of sand every year, according to a report by UN Enivironment Programme (UNEP).
Around the entire globe each year it is enough to build a wall of sand 27 metres wide and 27 metres high around the entire globe each year, this is equivalent to 18 kilograms a day per person.
In cases when it is taken from coasts or rivers can have a serious environmental impact on ecosystems, erosion and diodiversity, Scientists warn sand extraction of such scale.
“We just think that sand is everywhere.” said Sciluzzi, Climate Scientist at UNEP and Professor at the University of Geneva, during a webinar hosted by think tank Chatham House.
“We never thought we would run out of sand, but it starting in some places. It is about anticipating what can happen in the next decade or so because if we don’t look forward if we don’t anticipate, we will have massive problems about sand supply but also about land planning.”
Current efforts to improve management of sand resources at local, national and global levels are uneven suggests Chatham House.
