Despite the negative effects, the Columbian Exchange was important to both areas. It was a very helpful thing. Some positive effects involve all the different things they exchanged. The Americas had what Europe wanted, and Europe had what the Americas wanted. So it worked out both ways. Some of the things they exchanged were crops such as tomatoes, beans, potatoes, bananas, sugar canes, etc. They didn't really "exchange." The people brought it with them. So basically, it was like bringing stuff to a whole new place. Europe brought Christianity to the Americas and they taught people their language. From that, people in the Americas learned a lot. The Columbian Exchange had some bad outcomes, but it was used for a long time.
