Alfred coined the term Columbian exchange in 1972. The Columbian exchange started to connect the New and Old Worlds with the transmission of ideas, plants, animals, and diseases. Two worlds that had grown apart with very different organisms started to become homogeneous (Crosby, 1972).
Okay Americas, you give me all your money, food, and resources, and I'll give you a religion you don't want and an incurable illness. Oh, and I'll even throw in some new crops you can grow for me.. There you pretty much have the essence of the Columbian Exchange. A phrase coined by historian Alfred Crosby, the Columbian Exchange describes the interchange of plants, animals, and diseases between the Old World and the Americas following Columbus' arrival in the Caribbean in 1492.
