What were the short and long term impacts of the rise of slavery there?

Impact of the rise of slavery differs from one another as given below.

Explanation:

For the first time, slaves became part of the economy in the New World after the discovery of America in 1492 by Christopher Columbus. The triangular trade introduced slavery and led to the beginning of the slave trade from Africa. In the long term, it introduced racism and cruelty by recognising African people by their descent with slavery who, according to the whites, needed to be controlled. A short term impact would be the suffering they suffered, including death and separations in the North. Slavery was banned in the North as people considered it to be evil and unlawful.
