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).
Disease was one of the largest unintended consequences of the Columbian Exchange. The arrival of the Europeans brought this great exchange, which enriched the world with trade of plants and animals, but it also connected people of the world who had at this point never come in contact with each other.
