Before revision: These could include: discharge plumes that have effects of clogging feeding mechanisms of plankton Noise and light pollution that cause reduced visibility for predators Ecotoxicological or chemical temperature changes in the water quality Destruction of seabed and habitat The dump-truck-sized collection vehicles that scour the seafloor for nodule-bearing sediment, do necessarily destroy the top of the seabedoften more than three kilometers below the surface.
