Due to the global rarity of deep sea hydrothermal vent ecosystems, the impact of vent mining would be disproportionately high relative to terrestrial mining. Fullscale nodule mining on the abyssal plain would affect thousands of square miles of ocean floor, kill attached invertebrate communities, and create huge subsea sediment plumes that would flow and settle over thousands of square miles of seafloor.
