As the deep ocean faces growing peril from climate change, seabed mining and other threats, scientists have discovered that seafloor sediments are home to vast populations of previously unknown organisms that may play a crucial role in carbon sequestration and marine food webs. The finding will only further complicate the debate over the tradeoffs from deep seabed mining for critical metals needed for a transition to green energy.
[ More ]Canadian startup DeepGreen is touting seabed mining as a green alternative to land-based mineral extraction but scientists warn that seabed mining could result in environmental damages “irreversible on multi-generational timescales.”
[ More ]DeepGreen built a nearly $3 billion valuation on the dream of gently excavating the ocean floor. Now environmentalists want to block its plans to go public.
[ More ]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.
