The Colombian exchange created a great cultural impact on The Americas which can be seen even today. Wiping out up to ninety percent of Native Americans, the settlers that came to America created a biological imperialism on another scale. The demand from European countries for exportation quickly created a market that settlers could benefit from and Native Americans could not compete with. Deforestation started on a massive scale due to the high availability of lumber, and seas quickly started to be depleted of fish. The introduction of livestock and agriculture created an environmental revolution. Wheat, oats, and barely are all new foods brought to the Americas which also had weeds in between the seeds which displaced native flora and fauna.
