This vast island is characterized by its unique geography, consisting mainly of ice sheets and tundra, and it has a sparse population predominantly concentrated along its coasts. Greenland's landscape features stunning natural beauty, including glaciers, fjords, and the Northern Lights. The island is crucial for scientific research, especially concerning climate change, as its melting ice is closely monitored. It holds a rich cultural heritage among the indigenous Inuit people.
