Greenland is the world’s largest island, covering approximately 2.166 million square kilometers. It is classified as an island because it is surrounded by water and is not connected to any continental landmass. Despite its vast size, Greenland has a relatively small population that primarily inhabits the coastal areas. The interior of the island is largely covered by ice, making it largely uninhabitable. Greenland's unique geography and climate play a significant role in its ecology and human settlement, with traditional communities relying on fishing, hunting, and gathering for sustenance.
