Southern Sanctuary?

The UK government is apparently supporting a suggestion to set up a 1.8m square km (the square is important as we are dealing with an area rather than a straight line!) reserve in Antarctica to protect Blue whales, Leopard seals, Orca and penguins by banning fishing and hunting in that area (https://www.theguardian.com/environment/2018/oct/17/uk-government-backs-antarctic-wildlife-reserve-worlds-biggest). This would also be a beneficial development for the planet as the seas in that location absorb enormous amounts of carbon dioxide. Having said that, it doesn't actually cost the UK any money (they have not been so 'green' on their home turf) and there is no guarantee that all other countries will support such a move.
