Explanation:

Positive impacts include territorial expansion of the United States, which opened up new land for economic development (such as agriculture, mining, and trade) and helped establish the U.S. as a continental power. It also fueled westward migration, spurring the growth of new towns, infrastructure like railroads, and increased national unity among white settlers.

Negative impacts center on the violent displacement and genocide of Indigenous peoples, who were forced off their ancestral lands via policies like the Indian Removal Act, resulting in widespread death, loss of culture, and marginalization. It also intensified tensions over slavery, as the expansion of new territories raised debates about whether slavery would be allowed there, contributing to the lead-up to the U.S. Civil War. Additionally, it led to the exploitation of natural resources and the erosion of Indigenous ecological knowledge.
