Final answer:
Christopher Columbus's discovery of America had both positive and negative impacts, as it led to cultural exchange and revolutionized lifestyles through the introduction of new commodities, but also initiated colonization and exploitation and caused harm to the indigenous populations.
Step-by-step explanation:
Christopher Columbus's discovery of America had both positive and negative impacts, and it is difficult to pick just one side without acknowledging the other. On one hand, Columbus's discovery connected two worlds and led to cultural exchange, which introduced new commodities and foods to Europe and Asia, such as cattle, horses, tea, coffee, tobacco, potatoes, chocolate, corn, and tomatoes. This exchange revolutionized the lifestyle of people in both the Old World and the New World. On the other hand, Columbus's arrival initiated colonization and exploitation, bringing about negative consequences for the indigenous populations, including depopulation due to European diseases like smallpox and influenza. These exchanges and conflicts shaped the course of history in both America and Europe.
