In many metropolises around the world, especially in English speaking countries, it is not surprising to see people from different ethnics or cultures living and working together. How this comes into existence and what influence this exerts on our society will be discussed as follow?

Such co-existence of races in many major cities can largely be attributed to modern transportation and telecommunication technologies, to be specific, airplanes， computer and the internet. This advancement increases mobility of human and promotes communication and interaction between people without limitation of space and time. The earliest and most obvious representation lies in the globalization of trade and business which expand beyond the national border and facilitate people involved to immigrate permanently or live overseas temporarily. Some countries like USA or Australia have tradition of immigration and they welcome distinctive cultures and ethnics or at least they tolerate differences well. In these places, multi-culture is the embodiment of a high level of civilization.

Of course melting pots have caused some concerns or problems. Races with different religions sometimes collide due to misunderstanding of other cultures. The dominant culture may have the tendency of assimilating or marginalizing other minor ethnics, leading to the young immigrated generation being confused with their cultural and political identity. Multiculturalism aimed at establishing an egalitarian society is deemed by some people to be over simplistic and idealistic.

However, this trend of globalization seems impossible to reverse and trying to deny it would not be as wise as to keep pace with it. Cultural diversity is believed to stimulate open-mind of people and the creativity and innovation of a society due to accommodation and communication of different ideas, therefore enhancing productivity and prosperity of a society in both economic and cultural terms. Looking back human history, brilliant ancient civilizations always featured a high level of inclusiveness of exotic cultures and religions.

To conclude this essay, the integration of cultures and ethnics in many areas in the world reflects the desire of human beings for widening their horizon and exploring the unknown world and this in turn accelerates more contact between distinctive cultures and ethnic groups. Human society would be more dependent on each other and realizing this sooner would be helpful for us to adapt to the current trend.
