What was a negative impact that Lewis and clark did?

Answer 1

One negative impact of Lewis and Clark's expedition was the disruption of Native American societies and ecosystems. Their exploration and subsequent American expansion led to increased settlement, resource extraction, and conflicts over land, which often marginalized Indigenous populations. This encroachment resulted in loss of traditional lands, cultural alterations, and significant hardships for many Native communities. Additionally, the introduction of new diseases by explorers and settlers further decimated Indigenous populations.
