How did the columbian exchange affect european trade?

The Columbian Exchange greatly affected European trade. The Columbian Exchange provided Europe with more goods to sell. Items such as tobacco, sugar, tomatoes, potatoes, corn, furs, etc. became staples in Europe, and this greatly stimulated the economy of various countries and trade all over the continent. Moreover, the fact that the Americas became colonized also affected trade, as it created a market in America for European goods, expanding trade once more.
