Answer:
The Columbian Exchange was a transfer of people, goods, and ideas between the New World and the Old World (mostly Europe).
Explanation:
Columbian exchange is the name given to the intense exchange of animals, plants, food, human populations, infectious diseases and ideas between the Eastern Hemisphere and the Western Hemisphere, that began in the late 15th century.
The Colombian exchange greatly affected almost every society on the planet. New diseases transmitted by Europeans (many of them from Asia), to which indigenous peoples did not have immunity, deprived many cultures. Data on pre-Columbian populations in America are uncertain, but estimates of population-induced losses from these diseases between 1500 and 1650 range from 50% to 90%.
At the same time, the contact between regions circulated a wide variety of new crops and livestock which supported the increase of the population. Early explorers brought new products to Europe such as corn, potatoes and tomatoes, which became determinants in Eurasian cultures in the 18th century. Similarly, Europeans introduced cassava and peanuts in Southeast Asia and West Africa, which thrived on poor soils, supporting the growth of populations in hitherto low-income areas.
