On the plus side, the Columbian Exchange brought new crops like tomatoes and peppers to the Old World, which totally revolutionized their cuisine. It's hard to imagine Italian food without tomato sauce, right? However, the exchange also had some major downsides, like the spread of smallpox, influenza, and malaria, which decimated Native American populations who had no immunity to these diseases. Yeah, not so funny anymore.
The Old World also got some new animals, like horses, sheep, and goats, which helped with transportation, food, and fashion (hello, wool coats!). But, the New World got some not-so-great animals, like rats and pigs, which brought diseases and environmental chaos. It's like the ultimate good news, bad news joke.
