Final answer:
The Columbian Exchange in Europe had positive effects such as new food sources and potential cures for diseases.
Step-by-step explanation:
The Columbian Exchange refers to the exchange of plants, animals, diseases, and ideas between the Old World (Europe, Africa, and Asia) and the New World (the Americas) following Christopher Columbus' arrival in 1492.
One positive result of the Columbian Exchange in Europe was the introduction of new food sources. For example, crops like maize, potatoes, and tomatoes were brought from the Americas to Europe, which significantly expanded the European diet and improved nutrition.
Another positive result of the Columbian Exchange was the potential for cures of diseases. While the exchange also led to the spread of diseases like smallpox, the introduction of new plants and herbs from the Americas provided Europeans with new remedies and cures.
