The European colonization had devastating impact on Native Americans due to environmental changes and the introduction of diseases:
- The introduction of European weapons linked to the popularity of beavers led to overhunting. <u>Overhunting led to the extinction of beavers which affected the ecosystem as a whole. Europeans also brought pigs to the new land that ended up eating the foods deers and other animals depended on leading to scarcity.</u>
