World's first legally binding treaty to protect #oceans and marine life takes effect

The High Seas Treaty or Biodiversity Beyond National Jurisdictions (BBNJ) Agreement, will govern about two-thirds of the planet's oceans including vast areas beyond any country's borders.

But how those protected areas will actually be monitored and enforced is undecided and will pose a challenge.

Australia, New Zealand, the United States, and the United Kingdom remain as signatories and have yet to ratify it.
