Explanation:

“A report to a UN ocean conference in New York points out that more than 60% of the ocean has no rules because it’s outside national jurisdiction. It says the open ocean is at risk from climate change, over-fishing, deep sea mining, farm pollution and plastics.” … The UN is focusing discussion on three areas:

• Setting up a legal framework for marine conservation areas on the high seas – or other spatial measures like banning destructive fishing gear in vulnerable places;
• A more rigorous environmental impact before industrial activities are undertaken;
• Developing rules around marine genetic resources so all nations get a share of the wealth of the seas.

Together they are categorised under a new UN acronym – BBNJ. That’s Biodiversity Beyond National Jurisdiction.
