US Secretary of State John Kerry joined forces Monday with Australia and New Zealand to call for marine sanctuaries in Antarctica, as conservationists sought a fishing ban in the pristine seas.
"Antarctica is a collection of superlatives. It's the highest, coldest, the windiest, the driest, the most pristine and the most remote place on Earth," Kerry told a gathering organized by the Pew Charitable Trusts.
"And it has beguiled humankind for centuries as people have sought to understand it," he added, arguing that the waters of the Southern Ocean, home to 16,000 species, are a "living laboratory."
The United States and New Zealand have drawn up a proposal for a marine sanctuary covering 1.6 million square kilometers (640,000 square miles) for the pristine Ross Sea, the world's most intact marine ecosystem.
Nations led by Australia, France and the European Union also want to protect 1.9 million square kilometers of critical coastal area in the East Antarctic.
But the proposals were blocked when November talks of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), made up of 24 countries and the European Union, ended without resolution in Australia.
Now the nations are boosting efforts to get the two sanctuaries approved at a special meeting of the group in Germany in July.
Kerry told Monday's gathering at the National Geographic Society he believed the world can "work together to ensure that Antarctica remains a place devoted to peace and devoted to expanding human understanding of this fragile planet we live on.
"This is one of the last places we could do this, and I think we owe it to ourselves to make it happen."
But conservationists argue the proposals do not go far enough to protect the marine life -- notably the Antarctic toothfish, which is fished in huge quantities and served as Chilean sea bass on restaurant tables around the world.
The Ross Sea proposal, while creating a reserve to protect Adelie and emperor penguins, as well as killer whales and Weddell seals, would still allow some 3,000 tonnes of toothfish to be commercially caught each year.
Pew urges the zone "to be designated a no-fishing area so that the integrity of the entire ecosystem can be maintained," it said in a statement.
