What was the change in the eastern hemisphere caused by the columbian exchange?
The Columbian Exchange resulted in an exchange of plants, animals, diseases, and technology between the Eastern and Western Hemispheres. This led to the introduction of new crops, like maize, potatoes, and tomatoes, in the Eastern Hemisphere, improving agricultural practices and increasing food production. It also transferred diseases like smallpox to the Eastern Hemisphere, causing significant population declines among indigenous communities.
