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).
The long-term effects of the Columbian exchange included the swap of food, crops, and animals between the New World and Old World, and the start of the transoceanic trade. In order to produce a profit, Portuguese explorers were the first to established sugar cane plantations in Brazil.
