Scientists are only beginning to understand the deep sea’s complex ecosystems, the many vulnerable species that call it home, and the global processes they influence. Advancing deep-sea mining risks:
Long-term ecological damage: There’s no proven way to restore deep-sea ecosystems once damaged.
Widespread pollution: The huge clouds of sediment unsettled by mining activity can spread hundreds of miles, spreading heavy metals and potentially toxic chemicals that pose risks to marine animals and people alike.
Destroy critical fish habitat: Strip mining seamounts and other deep-sea features wrecks essential habitat for some of Alaska's most important fisheries.
Undermining habitat protections: Many proposed leasing areas have already been identified, and set aside by fisheries managers, as essential habitat.
If deep-sea mining moves forward, Alaskan communities will bear the brunt of the risks without any guarantee of economic reward. Fisheries could be irreversibly harmed by stirred-up sediment plumes and decimated habitat, as the extracted minerals themselves are shipped and processed outside Alaska. It's a lose-lose situation.
