Seabed mining debate stirs again in the Pacific

A group of researchers says damages from seabed mining would be significantly less than land-based mining.

DeepGreen has a license to explore the seabed of international waters in the Clarion Clipperton Zone, and has three exploration contracts which are sponsored by Nauru, Kiribati and Tonga.
