Step-by-step explanation:
Summary of the Columbian Exchange
The Columbian Exchange refers to the widespread transfer of plants, animals, culture, human populations, technology, diseases, and ideas between the Americas and the Old World in the 15th and 16th centuries, following Christopher Columbus's voyages. This exchange had a significant impact on both the Americas and the Old World, altering their agriculture, environment, and societies profoundly.
Effects on the Americas
In the Americas, the introduction of animals such as pigs, sheep, chickens, and cattle by Europeans augmented the variety of food sources. However, the most catastrophic impact was the transmission of European diseases, which resulted in the death of a vast majority of the indigenous population. Crops such as maize, potatoes, and cassava were exported to the Old World, reshaping diets and economies.
Effects on the Old World
In the Old World, the arrival of new crops led to agricultural diversification and supported population growth. The influx of precious metals from the Americas led to both economic expansion and inflation, changing the dynamics of wealth and trade. This exchange also laid the groundwork for a global economy, where a vast variety of goods became available worldwide, vastly altering consumption patterns and leading to the creation of new industries.
