What were some of the positive and negative consequences of the columbian exchange

The Columbian Exchange had positive and negative consequences.

Some of the positive consequences were the introduction of different nutrients and food supplies into the Old World, such as corn or potatoes. This improved the diet of most Europeans, leading to a population growth in the next generations.
