Could you provide a summary of the details on North America in this text?

Please only summarize the text under this line:

Northern North America is occupied by Canada, the second-largest country in the world, the US state of Alaska, and the Danish self-governing territory of Greenland. Much of Greenland is covered by ice, and all these regions are sparsely populated, although there are several large cities in Canada. These are mainly in the south of the country and on the Pacific coast near the stunning Rocky Mountains. Huge oil and mineral reserves have brought wealth to both Canada and Alaska.

Alaska was part of Russia until 1867, when it was sold to the US for $7.2 million. Most Americans thought this was a huge waste of money until gold was discovered there in 1896, attracting many people hoping to make their fortune. The discovery of oil in the Arctic Ocean in 1968 brought great wealth to the state, and tourism is also a major source of income.

The First Nations and the Inuit peoples lived in Canada long before Europeans began settling there in the 17th century. They number about 900,000 people, or 4 percent of the population, and have kept many of their traditional customs and traditions. In 1999, the self-governing Inuit homeland of Nunavut was created in northern Canada.

Greenland is the world’s largest island, but has a population of less than 60,000 because its climate is so harsh and cold. Most live in small settlements along the coast, making a living from catching fish, shrimp, and seals. There is a small network of roads, but dogsleds and planes are more reliable than cars for getting around.

The region includes Canada, Alaska, and Greenland with a low population density. Canada has large cities in the south and on the Pacific coast close to the Rocky Mountains. First Nations and Inuit peoples reside in Canada and have preserved their customary practices. Alaska, which was formerly part of Russia, is a valuable source of oil and minerals. Greenland, the world's largest island, has fewer than 60,000 inhabitants who make a living by fishing and hunting along the coast.
