What part of the Columbian exchange affected?

The Columbian Exchange significantly impacted agriculture, diets, and ecosystems across the globe. The introduction of New World crops like potatoes, tomatoes, and maize to Europe and Asia transformed food production and consumption patterns, leading to population growth. Conversely, the exchange also facilitated the spread of Old World animals and diseases to the Americas, which had devastating effects on Indigenous populations and altered local ecosystems. This complex interplay reshaped economies, cultures, and Demographics in both the Old and New Worlds.
