One World Government/One World Citizens

Anyone?
What does it imply??
The only difference is preserving our cultural heritage.
What is cultural heritage?? If you agree that each person has a unique personality, each culture represents such unique people.
If one appreciates culture, one learns to appreciate the differences in humanity. Cultures leads to people's difference, government is the equalizer. But in this case, the government should work to preserve cultures.

(I do several volunteer work in my area, this was one of the topic this week of our cultural conversation/discussions).
