Digestive Glaciers Sand Deposes Widely Open




(Newser)

In a unique positive cycle of climate change, a new study discovered that Greenland could be a major exporter of sand while its glaciers were lost in the sea. As world temperatures rise, the vast ice of the island is rapidly melting, and many sediments are washed in the oceans, reports Reuters. The Greenland population of 56,000 can see significant economic strengthening from sand mining and gravel and exporting it to other parts of the world. "Greenland will benefit from the challenges brought about by climate change," says a group of scientists. One described the melted ice sheet as a giant "tap that pours sediment to the shore." The amount of sand delivered by the country's coast annually is estimated to cost more than half of Greenland's GDP of about $ 2.22 billion, and the amount is expected to double over the next quarter-century.

The global sand market is worth $ 99.5 billion in 201

7, and the pie is likely to grow due to future shortcomings and rising demand. By 2100, it is expected to reach $ 481 billion. The sand is used in everything from concrete to computers, at the opposite, and a global black market has grown from a tremendous lack of things. Of course, mining and export of sand may be bad for the environment, while dredging up sediment may cause further damage to the marine ecosystem. The exploitation of sand reserves can be controversial due to the effects of the "clean Arctic landscape," ScienceDaily reports. "When we begin our research, we have no idea that our results will promote the idea of ​​establishing the sand mining industry in Greenland," said one researcher. "It only shows how unpredictable science can be." (Read more sand stories.)
