How did the columbian exchange effect the old and new worlds?

The Columbian Exchange significantly transformed both the Old World (Europe, Asia, and Africa) and the New World (the Americas) by facilitating the transfer of crops, animals, diseases, and cultures. In the Old World, the introduction of new staple crops like potatoes and maize led to population growth and changes in dietary practices. Conversely, the New World experienced devastating impacts from European diseases, which decimated indigenous populations. This exchange ultimately reshaped economies, societies, and ecosystems on both sides of the Atlantic.
