Globalization is a process that has made the world a place without boundaries, where people may be restricted from ravelling from one place to the other with visas, but increased interdependence among nation states has made transcending boundaries much easier than they ever have been.
According to the Stanford Encyclopedia of Philosophy,
Covering a wide range of distinct political, economic, and cultural trends, the term “globalization” has quickly become one of the most fashionable buzzwords of contemporary political and academic debate. In popular discourse, globalization often functions as little more than a synonym for one or more of the following phenomena: the pursuit of classical liberal (or “free market”) policies in the world economy (“economic liberalization”), the growing dominance of western (or even American) forms of political, economic, and cultural life (“westernization” or “Americanization”), the proliferation of new information technologies (the “Internet Revolution”), as well as the notion that humanity stands at the threshold of realizing one single unified community in which major sources of social conflict have vanished (“global integration”).
