Deep sea dwellers will soon face massive industrialization of their ocean ecosystems.

Deep sea ecosystems are under threat of mass industrialization, warned a panel of scientists on Sunday.

Speaking at the American Association for the Advancement of Science meeting in Chicago, the scientists warned that without international cooperation with a focus on "deep-ocean stewardship," deep sea mining will follow the destructive examples set by commercial fishing and offshore fossil fuel operations.

Vast tracts of deep seabed are already being leased by commercial mining operations, said panelist Professor Lisa Levin, who heads the Center for Marine Biodiversity and Conservation at the Scripps Institution of Oceanography.

Levin told the conference that the surge in demand for consumer devices, such as portable electronics and batteries for hybrid vehicles, is pushing mining companies to expand their operations to the ocean floor to seek out hard-to-find rare earth elements such as nickel, cobalt, manganese and copper.

...the phrase "hard-to-find rare earth elements such as nickel, cobalt, manganese and copper" is incorrect, or misleading at best.

Yes, rare earth elements, are difficult to extract because they are dispersed and are not often found concentrated in the ores of rare earth minerals.

However, "nickel, cobalt, manganese and copper" are NOT rare earth elements:

As defined by IUPAC, a rare earth element (REE) or rare earth metal is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides plus scandium and yttrium.[2] Scandium and yttrium are considered rare earth elements since they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties.

The lanthanides are:

Lan­thanum, Cerium, Praseo­dymium, Neo­dymium, Prome­thium, Sama­rium, Europ­ium, Gadolin­ium, Ter­bium, Dyspro­sium, Hol­mium, Erbium, Thulium, Ytter­bium, and Lute­tium
