Read the argument below regarding environmental policy and marine mining, then match each statement from the text to its corresponding logical role within the argument:
"Proponents of deep-sea polymetallic nodule mining argue that extracting seabed minerals is essential to supply metals for green technology transitions without expanding terrestrial mining's ecological footprint. However, recent oceanographic surveys indicate that benthic ecosystems recover far more slowly from physical disturbance than land-based biomes do. Because deep-sea sediment plumes can travel hundreds of kilometers, disrupting midwater marine food webs, the environmental costs of abyssal mining are likely to exceed those of conventional land extraction. Therefore, international regulators should institute an immediate moratorium on commercial seabed mining, regardless of projected economic benefits."
