Although you did not include any context or reference, we can help to answer in general terms.

I believe some of the results Europeans never expected was the death of almost 80% of the native Indians in the Americas due to the many new diseases brought by the European colonists. We are talking about diseases such as smallpox, chickenpox, malaria, cholera, influenza, among many others.

New World slavery could be said was related to the Columbian Exchange in that it was part of the Atlantic Slave trade in which African slaves were transported in unhealthy conditions to the Americas and were sold to landlords. Historians consider that approximately 10 million African slaves were sold to landowners in the American territory.
