The trouble is that the CCZ is pristine, scarcely explored and whole of unidentified species that could be beneficial in their individual suitable. Researchers are dashing to have an understanding of the ecosystem and the likely impacts of mining, as journalist Olive Heffernan shares, and the Global Seabed Authority has to determine before long irrespective of whether to let significant dredging of this exceptional natural environment.
