What was the Columbian exchange

The Columbian Exchange was a widespread exchange of animals, plants, foods, human populations (including slaves), and diseases between the Eastern and Western hemispheres. It was named after Christopher Columbus, who was one of the first explorers to facilitate these exchanges after his initial voyage to the Americas in 1492. The term "Columbian Exchange" was first used by the historian Alfred W. Crosby in his book, "The Columbian Exchange: Biological and Cultural Consequences of 1492". This exchange of goods, ideas, and people had a profound impact on the world, as it transformed diets, environments, and populations in both hemispheres.
