query: How many people are in Antarctica?
passage: Demographics of Antarctica
The population of persons doing and supporting scientific research on the continent and its nearby islands south of 60 degrees south latitude (the region covered by the Antarctic Treaty)[3] varies from approximately 4,000 in summer to 1,000 in winter; in addition, approximately 1,000 personnel including ship's crew and scientists doing onboard research are present in the waters of the treaty region.
passage: Arctic Cordillera
The landscape is dominated by massive polar icefields, alpine glaciers, inland fjords, and large bordering bodies of water, distinctive of many similar arctic regions in the world. Although the terrain is infamous for its unforgiving conditions, humans maintained an established population of 1000 people – 80% of which were Inuit. In addition, the landscape is 75% covered by ice or exposed bedrock, with a continuous permafrost that persists throughout the year, making plant and animal life somewhat scarce. The temperature of the Arctic Cordillera ranges from 6 °C in summer, down to −16 °C in winter. Vegetation is largely absent in this area due to permanent ice and snow.
