What were the consequences of slave trade in Africa?

In essence, the consequences were that African Americans became imported into the United States. This slave trade also led to the evolution of the United States, and allowed it to grow, while slaves did all the work. This led to a mixture of races eventually, and to the major population of African Americans that exist today. Slave trade also seprerated the north and south, and still can bee seen to this day as more racism may exist in the southern states than up north.
