The document discusses the Columbian Exchange between Europe and the Americas following Columbus' arrival. Key aspects of the exchange included animals, plants, and diseases. Europeans brought horses, pigs, cattle and other livestock, as well as crops like wheat, sugar, and grapes. Americans crops like maize, potatoes, and cacao also spread to Europe. However, the exchange of diseases had devastating impacts, as Native Americans lacked immunity and populations declined sharply due to smallpox and other illnesses. This created a labor shortage that was eventually filled by the slave trade from Africa. The exchange of foods and animals dramatically impacted global societies, economies, and cuisines.
