The U.S. government shutdown is threatening a long-awaited deal to create the world's largest marine sanctuary in Antarctica. Americans are among the biggest supporters of the proposal, but they might not make it to the negotiating table. On Wednesday, Oct. 16, 2013, U.S. Secretary of State John Kerry joined his counterparts from other nations in calling for the sanctuary to proceed. But the U.S. had apparently already suspended travel plans for its delegation. If they don't make it, the proposal probably will be put on hold until next year at least.
