USA HISTORY

Detailed explanation-1: -The impact was most severe in the Caribbean, where by 1600 Native American populations on most islands had plummeted by more than 99 percent.

Detailed explanation-2: -And so did every European, African, and Native American who wittingly or unwittingly took part in the Columbian Exchange – the transfer of plants, animals, humans, cultures, germs, and ideas between the Americas and the Old World.

Detailed explanation-3: -Possibly the most dramatic, immediate impact of the Columbian Exchange was the spread of diseases. In places where the local population had no or little resistance, especially the Americas, the effect was horrific. Prior to contact, indigenous populations thrived across North and South America.

Detailed explanation-4: -Meanwhile, in Asia and Africa, the domestication of herd animals brought new diseases spread by cattle, sheep, pigs, and fowl. Soon after 1492, sailors inadvertently introduced these diseases-including smallpox, measles, mumps, whooping cough, influenza, chicken pox, and typhus-to the Americas.

Detailed explanation-5: -Germs that brought disease had a huge impact as a result of the Columbian exchange (Walbert, 2008). Europeans brought smallpox and other diseases to the New World and diseases eventually killed off as much as 90 percent of the native population (Walbert, 2008).
