What compels us to leave home, to travel to other places? The great travel writer Bruce Chatwin described nomadism as an “inveterate impulse,” deeply rooted in our species. The relentless movement of the modern world bears this out: our relative prosperity has not turned us into a sedentary species. The World Tourism Organization, an agency of the United Nations, reported nearly a billion tourist arrivals in 2011. Some 200 million people are now living outside their country of birth.
Hanoi, Vietnam – In 1975 the ruthless communist dictator Pol Pot came to power in Cambodia, ushering in the reign of the Khmer Rouge. Pol Pot’s vision was one of an agrarian society founded on equality and self sufficiency. To achieve his goal, Pol Pot exiled everyone from the cities, closed the country’s borders with land mines, disbanded modern institutions associated with education, medicine, free trade, and the media, and forced all people in Cambodia to move to collective farms (ie. work camps) throughout the Cambodian countryside. The mass migration from the cities tore families apart and forced people to leave all of their belongings behind, while the loss of all social institutions completely halted the Cambodian economy and led to great sickness and starvation.
