This is a globalization-age.

Korea is becoming a mixed-race society. What kind of effects does it have? Every problem has advantages and disadvantages. It also has both of them. I agree with the mixed-race society. I'm sure its advantages can supply its disadvantages. Let's talk about the advantages.
First thing is about people's various. International marriage makes new kinds of people. Scientifically, mixed-race people are more evolutionary than pure-race people. This is a very desirable situation.
Second, what I think the most important one, it promotes globalization of Korea. Mixed-race people set their affection on two country which are his or her parents. These affection might be a big power of the contries' harmony. Also, their several cultures will help Korean globalization.
And It is the 3rd reason, it solves our rural bachelor's marriage problem. Now it is a serious issue in Korea. Surely, there are unpredictable matters in this society. We should keep this point in our mind and prepare.
