The Columbian Exchange changed the world's economies a lot by introducing new farming methods and trade. Here are some key ways it affected the economy:

1. New Crops:

   • New crops like potatoes, corn (maize), and tomatoes helped increase food production. For example, the potato helped the European population grow by 25% from 1700 to 1800.

2. Trade Networks:

   • By the 1600s, trade routes grew a lot, which caused global trade to increase by 300%.

3. Colonial Economies:

   • European countries set up large farms called plantations in the Americas. By 1800, sugar production increased by 40%.

4. Labor Systems:

   • The need for workers led to the forced movement of about 12.5 million Africans through the transatlantic slave trade between the 1500s and 1800s.

These changes helped create the modern global economy we know today.
