How did the introduction of animals alter the new world?

The introduction of animals to the New World significantly transformed its ecosystems and human societies. European settlers brought livestock such as cattle, pigs, and sheep, which altered land use, agricultural practices, and diets among Indigenous peoples. Additionally, these animals contributed to environmental changes, including overgrazing and the displacement of native species. Overall, the introduction of animals facilitated the establishment of European colonial economies and profoundly affected the cultural and ecological landscape of the Americas.
