Once thought too expensive and too difficult, commercial scale mining of the deep sea is poised to become a reality as early as 2019. But scientists warn reaching rare minerals on and under the sea floor could cause irreversible damage to an environment that is still poorly understood.
As new technologies come online, mining companies are probing depths from 5,000 to 16,000 feet to expose new deposits of manganese, copper, cobalt, and other rare-earth minerals necessary to build everything from smartphones to solar panels to electric cars.
“People are making new discoveries almost every week; we’re nowhere near plateauing in our understanding of these deep-sea ecosystems,” said Lisa Levin, a biological oceanographer at the University of California-San Diego. Continue Reading →
