Answer :
Final answer:
The Columbian Exchange refers to the process where plants, animals, diseases, and cultures were exchanged between the East and West after Columbus's discovering of America. Europeans introduced new commodities and diseases to the Americas, which led to the death of up to 90% of Native Americans. The most profound impact of colonization was the introduction of diseases to which natives had no immunity.
Explanation:
The Columbian Exchange had a profound impact beyond just the economic and political aspects. It refers to the exchange of plants, animals, diseases, ideas, religious practices, and cultural traditions between the Eastern and Western Hemispheres after Christopher Columbus encountered Native Americans in 1492.
Europeans, in this process, introduced new foods, plants, animals, and notorious diseases to the Americas, turning whatever they could into commodities. Native people, on the other hand, were exposed to diseases they had never encountered, almost decimating their population. It is estimated that up to 90% of Native Americans died from these infectious diseases after Europeans arrived.
European colonization's most profound impact was perhaps the introduction of diseases to which the natives had no immunity. Epidemics took the lives of many, with survival rates being lowest among young and old natives. Losing the older generation meant a loss of knowledge and tradition. The death of children had devastating implications for future generations.

The Columbian Exchange refers to the significant transfer of plants, animals, peoples, and diseases that occurred between the Americas and Europe/Africa following the arrival of Christopher Columbus in 1492.
This exchange had numerous effects on both sides of the Atlantic, significantly transforming societies, economies, and environments.
One of the most catastrophic and unintentional biological effects of the Columbian Exchange was the introduction of Old World diseases to the indigenous populations of the Americas. Diseases such as smallpox, measles, influenza, and malaria had evolved in Europe, Africa, and Asia over centuries, allowing many people in those regions to develop some level of immunity.
Key Points:
Introduction of Diseases: When Europeans arrived in the Americas, they brought these diseases with them. However, the Native Americans had never been previously exposed to such illnesses, resulting in a complete lack of immunity.
Population Decline: The impact was devastating. Estimates suggest that by 1650, the Native American population plummeted from around 100 million to approximately 6 million due to these diseases. Some regions witnessed the death of up to 90% of their indigenous populations.
Herd Immunity Absence: The concept of herd immunity, where a significant portion of a population becomes immune to a disease, did not exist among Native Americans for these introduced diseases. Therefore, the diseases spread rapidly and with lethal consequences.
Other Biological Transfers: Besides diseases, the Columbian Exchange involved the movement of various plants and animals. For instance, European livestock like pigs, sheep, and cattle thrived in the Americas, benefiting those who could access them. Conversely, crops like potatoes, maize, and tomatoes enriched diets in Europe and beyond.
