Final answer:
The Columbian Exchange facilitated the exchange of crops and ideas, leading to cultural and societal changes in different regions. It also brought diseases to the Americas, causing the deaths of a significant portion of the native population.
Step-by-step explanation:
The Columbian Exchange, which took place during 1450-1750 C.E., had a significant impact on peoples in various regions. It facilitated the exchange of ideas, technology, and crops, leading to cultural and societal changes in different regions. For example, American maize, potatoes, and cassava fed growing European, African, and Asian populations, allowing the building of new cities and industries. European animals such as pigs, sheep, chickens, and cattle thrived in the Americas, enabling both Native Americans and Europeans there to add and maintain animal protein to their diets. However, it also brought diseases from Europe to America, which caused the deaths of a significant portion of the native American population.
