The following examples address the two sides of the argument.
The Old World Influenced the New World More:
The Columbian Exchange did not simply influence the New World; it completely transformed and nearly destroyed it. Although crops, cattle, and technology provided the New World with new and practical tools, diseases such as smallpox brought from the Old World devastated the New World civilizations. Therefore, the Old World greatly influenced and affected the New World during the Columbian Exchange.
The New World influenced the Old World More:
The New World influenced the Old World by introducing new crops and livestock to European and world markets. These agricultural advancements helped to further increase the power of European countries. In particular, crops such as corn and potatoes became popular staples in many European countries, as well as in nations throughout the world.
