The Columbian Exchange: Crash Course World History #23

In which John Green teaches you about the changes wrought by contact between the Old World and the New. John does this by exploring the totally awesome history book "The Columbian Exchange" by Alfred Cosby, Jr. After Columbus "discovered" the Americas, European conquerors, traders, and settlers brought all manner of changes to the formerly isolated continents. Disease and invasive plant and animal species remade the New World, usually in negative ways. While native people, plants, and animals were being displaced in the Americas, the rest of the world was benefitting from American imports, especially foods like maize, tomatoes, potatoes, pineapple, blueberries, sweet potatoes, and manioc. Was the Columbian Exchange a net positive? It's debatable. So debate.

But the Columbian Exchange only applies to North America. The North Americans already had horses from the Spanish Conquistadors before the Columbian Exchange.

[IntroSpectre6x3]

"Native Americans" applies to both North and South America.

[RoScFan]

Yes I agree with Crosby. Maybe I'll read that book sounds really awesome. Fuck Columbus and his awful legacy

[seastormsinger]

But... how could you say globalization is wrong? I mean... Pizza!

Besides... it was basically inevitable. Meaning pizza was inevitable.

[xergxilla]

Didn't the Native Americans have horses that spread from the South American Conquistadors?
