One of the most serious problem raised nowadays between people is cultural diversity. So what is the definition of it and how we can avoid it?Cultural diversity is the quality of diverse or different cultures, as opposed to monoculture, the global monoculture, or a homogenization of cultures, akin to cultural decay. The phrase cultural diversity can also refer to having different cultures respect each other's differences. The phrase "cultural diversity" is also sometimes used to mean the variety of human societies or cultures in a specific region, or in the world as a whole. Globalization is often said to have a negative effect on the world's cultural diversity.This is not a bad thing but to make the world become a unified form, we should try our best to impulse the exchange of globalization all around the world.
