And a United Nations agency has concluded a deal to create the world’s largest marine reserve. Today’s agreement sets aside an area in Antarctica’s Ross Sea that’s nearly as big as the state of Alaska. This is U.S. State Department official Evan Bloom.

Evan Bloom: “We’ve had a real achievement today. We’ve created the world’s largest marine protected area, and that’s a major step forward for marine conservation globally. So, it’s a wonderful moment.”

The marine sanctuary is home to whales, seals, penguins and other animals. The agreement on the Ross Sea sanctuary came as the World Wildlife Fund released a shocking new study that finds more than two-thirds of the world’s wildlife could be gone by 2020.
