Greenland is rich in mineral resources, among which rare earth resources are particularly valued by the United States. As the climate warms, the Greenland ice sheet is in the process of accelerating melting, and mineral resources that were previously difficult to exploit are gradually becoming ready for exploitation.

At the same time, climate warming has also made the Northern Sea Route through the Arctic Ocean increasingly valuable for development, and the value of Greenland has also "increased." More importantly, the island is close to the North Pole and across the Arctic Ocean from Russia, which has important strategic value to the United States.

Greenland is located in northeastern North America, between the Arctic Ocean and the Atlantic Ocean. It is the largest island in the world, covering an area of ??2.16 million square kilometers. It belongs to Danish territory. Due to its high latitude, about four-fifths of the area is located in the Arctic Circle. 85% of the entire island is covered by ice sheets, with an average height of 5,000 feet. It has a typical cold climate and is rich in fresh water, coal and oil resources. Internationally, all landmasses surrounded by oceans smaller than Greenland are considered islands, and landmasses larger than Greenland are considered continents. Australia is the smallest of all continents. Greenland is huge, about 14 times the size of England.

It is often said that unlike Russia's greed, the United States has little desire for territory. However, after the founding of the United States, it annexed a large amount of land in Mexico, purchased Alaska formerly controlled by Russia, and purchased Louisiana and other places from France. No, Trump recently wanted to buy and sell Greenland. It is estimated that many people do not know that there is another area called Greenland. Greenland is the northernmost region, covering an area of ??2.1 million square kilometers, but has a population of only more than 50,000. This is a sparsely populated area, why does this happen?

When we use a world map, we discover why Greenland, the largest island in the world in North America, is so large that it appears even larger than Australia near the equator. In fact, the actual area of ??Greenland in North America is about 2.1661 million square kilometers, while Australia in Oceania near the equator is about 7.692 million square kilometers, which is about 3.5 times the former.

After Catalonia, Scotland and the Basque Country, Greenland still wants independence? Since the 18th century, sovereignty over Greenland has belonged to Denmark. Although they were granted autonomy, with only foreign and defense affairs now managed by Denmark, most people were not satisfied. They hope that one day the island will become real.
