Tourism represents the greatest mass migration in human history, and it is one of the most significant social, economic, and cultural phenomena of our times. Wars, military coups, political unrest, terrorist attacks, natural disasters, disease epidemics, and recessions all prove to be temporary set-backs as tourism continues to grow and extend its outreach to all parts of the globe and beyond, as civilian space travel enters its pioneering phase. And tourists keep on traveling, shrugging off criticisms leveled at them by serious travel writers and other anti-tourists, disregarding Hollywood’s ridicule and the postmodernist claim that tourism has become “ordinary” and offers little in the way of novel experiences.
