When we look back to the history of human being in recent 200 years, we will be surprising what a huge change modern technology has brought us. Trains and planes enable us to travel to everywhere we want. Internet and televisions communicate news to everyone. New technologies provide us a new standard of living, and I state that they are creating a single world culture.
Modern technology has shortened the distance between cultures, and made the world smaller. People can travel or migrate from one place to another very quickly. They see how people in other zones dress, speak and behave. The more exposure to other traditions and customs they do, the more likely they adopt to those. As a result, their own traditions and customs are replaced by a massive one.
