What is an effect of the columbian exchange?

One significant effect of the Columbian Exchange was the dramatic increase in the exchange of crops and livestock between the New and Old Worlds. This led to improved diets and agricultural practices in both regions, with staples like potatoes and maize transforming European diets and livestock such as cattle and pigs enhancing farming in the Americas. However, it also had negative consequences, including the spread of diseases like smallpox, which decimated Indigenous populations in the Americas. Overall, the Columbian Exchange profoundly reshaped societies, economies, and ecosystems across the globe.
