Sustainable Use of the Oceans: Overfishing + Pollution ‘Dead Zones’ Depleting Ocean Life (discussion)

Overfishing has depleted fish-stocks the world over. Subsidies and lack of enforcement of sustainability measures drive the fishing industry to deplete the very stocks on which its existence depends, while climate interference and global contamination are leaving oceans so hypoxic (oxygen deprived) they cannot support marine life. At least 405 such ‘dead zones’ have been identified across the globe.
