What was an effect of the columbian exchange?

Answer 1

One significant effect of the Columbian Exchange was the drastic shift in agricultural practices and diets across the globe. The introduction of New World crops like potatoes, maize, and tomatoes to Europe, Asia, and Africa greatly enhanced food security and population growth. Conversely, the exchange also facilitated the spread of diseases, such as smallpox, which devastated Indigenous populations in the Americas. This complex interaction between cultures led to profound economic and social changes across continents.
