Stat: Antarctica is home to more than 9,000 species found nowhere else on Earth. Story: They include Adélie and emperor penguins that depend on the nutrient-rich waters that surround the continent. In 2016, 24 countries and the European Union created the world’s largest marine protected area—encompassing 1.9 million square miles—in the Ross Sea. In this rebroadcast of a Pew event, the former president of Costa Rica and other ocean conservationists discuss the need to give other Antarctic waters this same protection.
