Prior to 1492, the Americas had been a separate ecosystem from Europe and Asia for thousands of years. Columbus's voyage of discovery started an exchange between the continents. The exchange of food groups led to the elimination of hunger worldwide but it also led to the exchange of diseases. European diseases decimated the native American population.
One long-standing question is which diseases were exchanged and which ones were already present on both hemispheres? New evidence shows that anthrax was already in America before Columbus. More details here.
