Greenland is the world's largest island by area (2,166,086 square kilometers or 836,330 sq mi) and has a population of 56,749, making it the least densely populated dependency or country in the world. Inhabited by Arctic indigenous peoples via Canada for at least 4,500 to 5,000 years, today Kalaallit or Greenlandic Inuit make up 88% of the population. Like their indigenous brothers and sisters, they face a number of common struggles: sovereignty, the right to self-determination, preservation of language and heritage, rights to land and natural resources, impacts from climate change and environmental damage, and recognition within local, federal, and international governments and laws.
