The correct answer is the following.
Indeed, the introduction of the slave trade and its expansion throughout the eighteenth century had a transformative impact on those captured as well as the global economy. However, it had a high cost on human lives.
African slaves were treated very badly during the period of their capture, enslavement, and seasoning. Although Africans died in massive numbers in captivity, slavery still proved hugely profitable to planters, merchants, elites, and others. It is regretful that humans in that time did not respect teh dignity and the rights of African people that suffered so much when they became slaves.
We are talking about the Slave Trade times in Africa, an important part of the triangular slave trade between America, Europe, and Africa. Historians believe that 12 million slaves were transported from Africa to America to be sold as slaves. African slave traders launched warring raids to acquire Africans to sell into slavery. They "shipped" the slaves into the ship and packaged them in inhuman conditions. Indeed, many slaves died during the trip before getting to the Americas. This trip was known as the Middle Passage.
