Explain the positive and negative effects of the columbian exchange (aka atlantic exchange) on the new world, old world, and africa.

The effects on the new world were mostly negative, since disease brought by Europeans caused epidemics that killed off most of the native population. For Europe, this was beneficiary since there were many goods thr Europeans could strip and take advantage of from the Americas. As for Africa, the trade of slaves was good economically at first for the Africans but as time went on it was negative.
