The Effects of the Columbian Exchange

One of the main changes caused by the Columbian Exchange was the ethnic changes that took place in the Americas. For instance, the Native Americans who were the only race in the Americas are now only a minuscule part of the American population, because of the diseases brought to the Americas by Europeans. Now people of European decent are the largest ethnic group. Another large ethnic group is people of Spanish and Native American decent, who make up most of the population of Mexico, and a good portion of the population of the United States of America. Also Africans, who’s ancestors were brought over as slaves, make up a large portion of the population of the Americas. The Columbian Exchange caused the largest change in human geography of all time. Another large change was the change of crops and animals. Europeans brought cows, chickens, pigs, and horses to the Americas. The Europeans brought many different crops back to Europe from the Americas. They brought back chocolate, coffee, tomatoes, tobaco, and many other thing that are now not only grown in the Americas, but also in Europe.
