When a country support a person/holiday such as Columbus, it shows the huge significance of a person or society as a whole to appreciate what Columbus did through his discovery of America.For example, like how he started the Columbian exchange, it brought plants, animals, & cultures. Also,if we didn't have the right plants we need to be treated we wouldn't survive. The exchange is important because it was widespread. Everyone around the world can get the items they needed.  He was the one who had brought every different cultures to one place.  If, it wasn't for him no one would have ever knew this place besides the Native Americans. The Native American would be the only one living in America. As of today many people from all around the world are living in the United States.
