Final answer:
The Columbian Exchange was the significant transfer of plants, animals, diseases, and technologies between the Old and New Worlds, leading to drastic changes in lifestyles, economies, and populations on a global scale.
Step-by-step explanation:
The Columbian Exchange accurately describes the ecological transfer of plants, animals, diseases, and technologies between the Old World (Europe, Asia, and Africa) and the New World (the Americas) following the voyages of Christopher Columbus in 1492. This exchange had profound impacts on nutrition, population growth, food culture, and disease prevalence worldwide. Foods like maize, potatoes, and cassava were introduced to Europe, contributing to population growth, while European animals such as horses and cattle were brought to the Americas, significantly affecting the lifestyle there. Unfortunately, disease exchange, primarily from the Old to the New World, resulted in the significant depopulation of the native populations due to lack of immunity.
The correct option that best describes the Columbian Exchange in the context of the given question is option B: an exchange of plants, animals, and diseases between Europe and the Americas. This event reshaped global economic systems, societies, and environments, marking the beginning of a new era of increased global interactions and the birth of a worldwide economy.
