Eurasia
Eurasia is a large landmass covering about 53,990,000 km² (or about 10.6%) of the Earth's surface. Often considered a single continent, Eurasia comprises the traditional continents of Europe and Asia, concepts which date back to classical antiquity and the borders for which are somewhat arbitrary. Eurasia, in turn, is part of the yet larger landmass of Afro-Eurasia, whereby Eurasia is joined to Africa at the Isthmus of Suez.
Eurasia has over 4.6 billion people, more than 69% of the world's human population.*
