Question

what was one negative impact of the columbian exchange on africa?

• it had little to no impact on african societies.
• it caused a decline in the farming of traditional african crops.
• it introduced invasive species that destroyed african ecosystems.
• it contributed to the atlantic slave trade and the loss of population.

Explanation:

The Columbian Exchange led to increased demand for labor in the Americas, which boosted the Atlantic slave trade. This trade forcibly removed millions of Africans, causing population loss in Africa. The other options are incorrect: the Columbian Exchange impacted African societies (so "It had little to no impact..." is wrong), it introduced new crops to Africa (not a decline in traditional farming), and invasive species were more associated with the Americas than direct destruction of African ecosystems.

Answer:

The option "It contributed to the Atlantic slave trade and the loss of population." (the fourth option, counting from the left)
