Seafloor mining: the DeepGreen method
When mining at sea the seafloor is stripped to allow the rock underneath to be ground and extracted; a process which decimates the sea life communities, as fish and plants are killed. Another factor is the effect of plumes on the local environment, as flurries of displaced sand and debris are sent up into the central column of the water.
