Explanation: And most of those slaves were not native-born, because the brutal living and working conditions prevented natural population growth. Slavery in the United States relied heavily on the importation of enslaved Africans, who were forcibly brought to the Americas to work on plantations and in other industries. The conditions of slavery were often brutal and inhumane, and many enslaved people suffered from malnutrition, disease, and physical abuse. As a result, the natural population growth of enslaved people was often limited, and the majority of those held in slavery were not born in the United States.
