No country has not been affected by the Columbian Exchange, whether directly, or indirectly (by crop diffusion then cultural diffusion inside the country). However possibly some communities have not been affected, but surely no country.
The columbian exchange is important because it has changed some life for the better. If the columbian Exchange had not happened, we wouldn't have the diversity in our diets that we have today. meats like beef and pork would be non-existant in he americas and foods like the tomatoes and maize(corn) would not be in the old world(Europe, Asia, and Africa). These along with many other crops, animals, and even beliefs have shaped our world for the better.
