The Mining of Sea Floor Nodules, is it part of the Green Plan A?

There is a lot of Ni, Co, Cu, Mn metals in seafloor nodules.  Mining them could be as destructive as open pit mining, who really knows?  But we need raw material resources to be able to build the new-green world, especially all the new electric vehicles.  So what is the plan for going green?  Do we have a master plan?  Is this where we expect to get the raw materials?  Are we willing to pay the environmental cost?  Does anyone know what the consequences are for deep sea mining?
