USA HISTORY

Detailed explanation-1: -One of the main negative effects of the Columbian Exchange was that diseases, such as diphtheria, measles, smallpox and malaria, carried by explorers and later the settlers, killed many Native Americans. When Native Americans died in large numbers from these diseases, European settlers needed a new source of slaves.

Detailed explanation-2: -More than guns, the most devastating result of the Columbian Exchange was the spread of disease. In the years following European invasion, it is estimated that up to 95 percent of the Americas’ total population died. That’s roughly 20 million people. The native population was almost wiped out.

Detailed explanation-3: -In terms of benefits the Columbian Exchange only positively affected the lives of the Europeans. They gained many things such as, crops, like maize and potatoes, land in the Americas, and slaves from Africa. On the other hand the negative impacts of the Columbian Exchange are the spread of disease, death, and slavery.

Detailed explanation-4: -To date, however, besides that which existed in the original Columbian Trade, the world-historical value of modern exchanges pales. It triggered mass African migration, the rise of African communities, the toppling of African empires, and the advent of racism against slaves.

Detailed explanation-5: -Christopher Columbus introduced horses, sugar plants, and disease to the New World, while facilitating the introduction of New World commodities like sugar, tobacco, chocolate, and potatoes to the Old World.
