The Columbian Exchange and Early Globalization's Global Impact

Introduction: A World Drawn Into Contact

Contact between the New World of the Americas and the Old Worlds of Europe, Africa, and Asia led to a massive exchange of goods on an unprecedented scale. As Marks (2015) puts it, "most parts of the world were drawn into regular, ongoing contact in ways that had never happened in the past" (p. 67). As Nunn and Qian (2010) point out, the so-called Columbian Exchange resulted in gains and losses for both the Old and New Worlds. Global trade routes in Europe, Asia, and Africa had existed for centuries, but after contact with the vast empires of the Americas in the sixteenth century, the world had become significantly more interconnected.

That interconnectedness was not limited to trade. Globalization also led to the exchange of diseases, with disastrous consequences — particularly in the Americas, but also in Europe (Nunn & Qian, 2010). The impacts of disease reverberated around the world as the decimation of Native American populations offered financial incentives to invest in the trans-Atlantic slave trade. Nunn and Qian (2010) show how the Spaniards' quest to exploit the natural resources of their American territories depended on the importation of enslaved labor from Africa. Thus, a kind of butterfly effect was taking place whereby an event in one part of the globe produced enormous consequences in another.

Disease, Demographic Collapse, and the Slave Trade

In addition to its role in driving the slave trade — creating a major humanitarian crisis and genocides that lasted for centuries — the exchange of disease also contributed to what Marks (2015) calls the "global crisis" of population depletion. This crisis could have either precipitated or exacerbated the Little Ice Age. The Columbian Exchange also transformed the ways people around the world eat, with consequences so dramatic that it is almost impossible to imagine that potatoes are not originally from Ireland and that chili peppers are not indigenous to Southeast Asia (Nunn & Qian, 2010). Similarly, the exchange caused the spread of various diseases worldwide, with lingering effects. It is even possible that the introduction of new food products generated patterns of disease epidemiology that have yet to be fully explored empirically, as Nunn and Qian (2010) also suggest.

Climate, Population, and the Little Ice Age

As Marks (2015) explains, dramatic reductions in population would have meant fewer emissions from burning and other human processes, subsequently causing global temperatures to drop. The Little Ice Age, in turn, had effects on crop production and led to changes in population migration patterns. Without even realizing it, European explorers and colonialists set in motion major changes to the world's climate and populations — changes that far exceeded their expectations or intentions.

Conclusion: Themes in the History of Globalization

In general, these two readings reveal several themes in the history of globalization. One theme concerns the major impact of the so-called Columbian Exchange, both positive and negative. The exchange led to a multilateral transfer of foodstuffs and other goods, helping Asia grow its economy as well as Europe, and even contributing positively to diversifying food sources around the world. However, the exchange also had deeply negative effects, including the spread of disease, the decimation of indigenous populations, and the entrenchment of slavery. Together, these consequences demonstrate how profoundly interconnected — and how unequally affected — the world's peoples were by the dawn of the modern global era.
