What is seabed mining and why does it threaten the oceans?

Seabed mining is a method of extracting metals and minerals from the seafloor. It's used to describe both deep sea, and shallower mining techniques, although the former tends to be referred to as Deep Sea Mining (DSM). Seabed mining is similar to techniques that have been used for extracting sand to make concrete or to replenish public beaches.

Cold-water coral reefs, also known as deep ocean reefs, are found from Norway to the Aleutian Islands. There are three kinds of coral reefs: fringing reefs, barrier reefs, and atolls. A fringing reef forms along the edge of a coast and is attached to land. It extends outward from shore like a shelf, just below the surface of the water.
