Describing Cultural difference I think cultural difference isn't only in our world,rather there is even in a community.Cultural difference is because of history of each country.for example,in iran some cultures are for the time of the kingdom of Koorosh and they continue to today.in the other words ,history of each country is effective in its culture.today except our ancient culture ,we have modern culture.for example in america there are a lot of different relatives with different cultures so urban culture has caused that they can live together.culture is also vulnerable.For example war threatens culture .cultural difference is even in a communiy,in iran we have lot of culture because we have a lot of relatives .cultural difference is everywhere ,but we should try to keep our most important culture that called 'Humanity'
