The project, which has been delayed due to funding difficulties, is operated by Canadian company Nautilus Minerals and is poised to extract copper from the seabed, 1600m below the surface.
Valuable minerals are created as rapidly cooling gases emerge from volcanic vents on the seafloor. Mining the seabed for these minerals could supply the metals and rare earth elements essential to building electric vehicles, solar panels and other green energy infrastructure. But deep sea mining could also damage and contaminate these unique environments, where researchers have only begun to explore.
The industry’s environmental impact isn’t the only concern. It’s been assumed by the corporate sector that there is limited human impact from mining in the deep sea. It is a notion that is persuasive especially when compared with the socio-ecological impacts of land-based mining. Continue Reading →
