Two ecosystems (naturally evolved
networks of organisms in a stable
environment) commingled and clashed
when Columbus waded ashore the
Americas. The flora and fauna of the Old
and New Worlds had been separated for
thousands of years.

Native New World plants such as tobacco,
maize, beans, tomatoes, and especially
the lowly potato eventually revolutionized
the world economy as well as the
European diet, feeding the rapid
population growth of the Old World.

These foods were among the most important
Indian gifts to the Europeans and the rest of
the world. Perhaps three-fifths of the crops
cultivated around the globe today originated
in the Americas.

In exchange the Europeans introduced
Old World crops and animals to the
Americas. Columbus returned to the
Caribbean islands in 1493 with
seventeen ships that unloaded twelve
hundred men with cattle, pigs, and
horses.

North American tribes like the Apaches,
Sioux, and Blackfoot swiftly adopted the
horse, transforming their cultures into
highly mobile, wide-ranging hunter societies
that roamed the grassy Great Plains in
pursuit of the buffalo.

The horses soon reached the North
American mainland through Mexico and
in less than two centuries had spread as
far as Canada.

Columbus brought seedlings of sugar cane,
which thrived in the warm Caribbean
climate. A “sugar revolution” took place in
the European diet, spurring the slavery of
millions of Africans to work the cane fields
of the New World.

Unknowingly, the Europeans brought other
organisms in the dirt on their boots and
the dust on their clothes, such as the
seeds of Kentucky bluegrass, dandelions,
and daisies.

Worst of all, in their bodies they carried
the germs that caused smallpox, yellow
fever, and malaria. Indeed Old World
diseases quickly devastated the Native
Americans.

Enslavement and armed aggression took
their toll, but the deadliest killers were
microbes, not muskets. The lethal germs
spread among the New World peoples with
the speed and force of a hurricane.

In the centuries after Columbus’ landfall,
as many as 90 percent of the Native
Americans died, a demographic
catastrophe without parallel in human
history.
