The globalization is a process that has its positives and negatives, thus it has its supporters and critics. This process has been gradually connecting people all over the world, get the countries to collaborate better in political and economic ways, as well as spreading out a certain type of culture, mainly the Western culture.
The spreading of the Western culture, with the globalization, unfortunately, threatens the folk cultures all around the world. The younger population are seeing the Western culture as superior and cool, so they are trying to practice it, while in meantime they are neglecting their own traditional culture, so nowadays, lot of the folk cultures, especially the smaller ones, are struggling to survive.
