How was the Columbian Exchange both beneficial and harmful?

The Columbian Exchange was beneficial as it facilitated the transfer of crops, livestock, and technologies between the Old and New Worlds, leading to increased agricultural productivity and population growth in many regions. However, it also had harmful effects, including the spread of diseases like smallpox, which decimated Indigenous populations in the Americas, and the introduction of invasive species that disrupted local ecosystems. Additionally, it initiated exploitative colonial practices and the transatlantic slave trade, leading to significant social and cultural upheaval.
