What was a significant impact of the Columbian Exchange on the world's biological landscape?

• It led to an increase in the diversity of plant and animal species globally.

• It caused the extinction of many species and reduced biological variation.

• It introduced new species only to the Americas, not to Europe.

• It had no lasting effect on global biodiversity.

What was the primary cause of the drastic decline in Native American populations after the arrival of Europeans?

• European brutality and warfare.

• Starvation due to crop failure.

• Diseases brought from the Old World.

• Forced migration and displacement.

What negative impact did the Columbian Exchange have on global biodiversity?

• It led to the creation of many new species.

• It caused the extinction of more species in 400 years than usual evolutionary processes.

• It resulted in a richer genetic pool for life forms.

• It had no significant effect on the environment.
