Cultural variation refers to the differences in social behaviors that different cultures exhibit around the world. What may be considered good etiquette in one culture may be considered bad etiquette in another.
There are many differences between the various cultures across the planet. These differences include the way people interact, what they wear and what they eat. Many cultural differences can be explained by the environment and resources of the region. For example, Japanese people eat more fish than residents of the United States because fishing is far more practical than raising land animals in Japan. Cultural variations become obvious when put side by side in large multicultural cities.
