Don't Vote The Columbian Exchange
By: Sydney Hubbard
What is the Columbian Exchange ?
What are Positive and Negative effects ?
Some negative effects are countries starved and had to move because when potatoes were the only thing the Irish ate and potato fungus came around thousands of people starved. Another negative effect is the Europeans brought over diseases like smallpox because the Europeans were immune but they spread them to the Americans. One last negative effect is rats gave diseases also which made other Americans die because they were not immune.
