Define “Columbian Exchange.” Who benefitted most from this exchange, Europeans or Native Americans?

What will be an ideal response?

ANSWER
At the point of contact, Europeans and Native Americans began an exchange of flora, fauna, and microbes that had a profound effect on both peoples. The Native Americans lost in at least two ways: Adoption of the tobacco culture stimulated more migration from Europe and threatened Native-American access to land; European diseases destroyed and demoralized Native-American populations, crippling their cultures and their ability to resist further European invasion.
