How did the Columbian exchange affect the Americas and Europeans?

The Columbian Exchange significantly transformed both the Americas and Europe by facilitating the exchange of crops, animals, and diseases. In the Americas, the introduction of European livestock and crops like wheat and sugar significantly altered agricultural practices and diets. Conversely, the exchange brought devastating diseases, such as smallpox, to Indigenous populations, leading to dramatic population declines. For Europeans, new crops like potatoes and tomatoes contributed to population growth and changes in culinary practices, ultimately fueling economic expansion.
