Sophia Dobbins The Columbian Exchange

    In class, we discussed the Columbian exchange and how it is responsible for the worldwide spread and diversification of several animal and plant species across continents. The Columbian Exchange had such a large effect on the environment that it altered it permanently to this day.  The effects of the Columbian exchange that started off as environmental changes bringing invasive species into new environments altering the biodiversity of the area, and bringing new crops and animals into the area trickled into economic and cultural changes. As diets changed, trade changed as there were now new crops in areas they had never been before, and cultures changed with the new lifestyles the newly found plants and animals brought.  The text about the Columbian Exchange posted in Scholar stated "The Columbian Exchange, as Crosby called it, is the reason there are tomatoes in Italy, oranges in the United States, chocolates in Switzerland, and chili peppers in Thailand." Without the Columbian Exchange, the world would look significantly different today. The Columbian Exchange also altered several different demographics throughout the world. As we all know the demographic in America changed significantly with the arrival of the Europeans and their animals. The Europeans brought over diseases that they had developed immunity to but the indigenous populations in America had no defense against killing a very large population of the indigenous population in America. If the Columbian exchange had never occurred the world would look different in every aspect, demographically, biodiversity, and agricuturally.
