Canada, Mainland China, and the United States have roughly equal land mass.

Most of Canada is uninhabited. It cannot sustain life.
A large portion of China is also deserted as it is inhospitable to life.

The United States has relatively little land area that cannot sustain life, however, due to economic and transportation limitations, some areas are becoming uninhabited by default.

The largest nation on the European continent, if Russia is eliminated because of its peculiar politics, is France. France has less than 6.6% of the land that the United States has. Hence the great tragedy that Napoleon sold the Louisiana Purchase so cheaply!

While one is entitled to one's own opinions, one is not entitled to one's own facts.
