Describe 2 effects of the columbian exchange, one positive and one negative.

The Columbian exchange involved the interaction of two cultural systems that previously had no interaction: European and Amerindian cultures in the New World. One positive aspect of this exchange was the introduction of European culture in the form of social, political and economic systems. The introduction of the English language, growth of towns and cities and systems of barter and currency. A negative impact involved the destruction and eradication of indigenous cultures through war, devastation and relocation. Perhaps the best example of this fact was the destruction of cultures in Mexico and South and Central America such as the Aztec, Maya and Inca.
