Detailed explanation-1: -When the Europeans arrived, carrying germs which thrived in dense, semi-urban populations, the indigenous people of the Americas were effectively doomed. They had never experienced smallpox, measles or flu before, and the viruses tore through the continent, killing an estimated 90% of Native Americans.
Detailed explanation-2: -Colonization ruptured many ecosystems, bringing in new organisms while eliminating others. The Europeans brought many diseases with them that decimated Native American populations. Colonists and Native Americans alike looked to new plants as possible medicinal resources.
Detailed explanation-3: -What were the secondary effects of European diseases on the Native American population? The secondary effects were starvation and malnutrition because there wasn’t enough people left to grow the crops. Another effect was political instability because a lot of important people died.
