How did population change in the Columbian exchange?

Answer 1

The Columbian Exchange, which began in the late 15th century, significantly impacted global populations by facilitating the transfer of crops, livestock, and diseases between the Old and New Worlds. This exchange led to population growth in Europe and Africa as new food sources, such as potatoes and maize, improved nutrition. Conversely, the introduction of diseases like smallpox devastated indigenous populations in the Americas, leading to dramatic declines in their numbers. Overall, the Columbian Exchange reshaped demographic patterns across continents.
