Starting after Columbus’ discovery in 1492, the Columbian Exchange lasted through the years of discovery. It impacted both the New and Old World in various ways such as socially, economically, and environmentally. It is mainly congratulated for the positive things that it brought such as the exchange of plants, foods, and different animals. Although, not all aspects of it were good. The Columbian Exchange can be blamed for the immense exchange of diseases which greatly affected both worlds. Disease was shared from Europeans to Native Americans and the other way around. The social impacts made on both the Europeans and the Native Americans drastically transformed ways of life. They suffered from disease that was foreign to them. The Old World was infected with Smallpox, Chicken pox, Measles, Yellow Fever, Influenza, and Malaria. Common New World diseases were as intense as Syphilis, Polio, Hepatitis, and Encephalitis. The Indian population was greatly impacted by the large numbers of disease the Europeans brought to the New World. The transference of diseases during the Columbian Exchange had a heavy effect on the world then and will continue to affect our world today. The advancements of technology made a profound difference on the Native Americans. When Europeans sailed the Atlantic Ocean and colonized the New World they immediately changed Native American culture. A written alphabet, new farming capabilities, and weapons are just a few of the ways both worlds were positively impacted. Because Native Americans had no written language, the Europeans knew it would be hard to establish treaties. They began teaching Native Americans to read and write to help break down barriers and join cultures. Europeans did not only teach their language for trading purposes. They used their alphabet to teach them about Christianity. This is just one example of the technological movement of the Native Americans and the Columbian Exchange. With an abundance of new plants being discovered in the Americas, it changed both the environment and the culture of the New World and the Old World. Several plants were brought from the Old World to flourish in the Americas. The two most important plants involved in the Columbian exchange were the potato and maize. Potatoes came from the Andes and could grow in thin soil and resist the cold. The poor European soil was just right for growing the crop and it grew into food for the lower class. Maize, American corn, was considered an alternative for wheat, because it grows at a quick pace and can also be grown in places wheat can’t. Europe, Asia, and Africa still implement maize in their diet, because it can be dried almost indefinitely. These plants made the New World into a place where the people had access to support and nourishment, as well as trading purposes.
