 This is despite that Esperanto has only existed for around 100 years.In comparison, the entire literature of Iceland (a country created in the 900s, and with a population of around 320,000 people) totals fewer than 50,000 books.Many speakers travel the world using the Pasporta Servo which is a free couchsurfing and homestay service combined, meaning that their trips are possible because they don't have to pay for lodging while at the same time they stay with people who speak a language they know fluently.
