The European presence in America spurred countless changes in the environment, negatively affecting native animals as well as people. The popularity of beaver-trimmed hats in Europe, coupled with Native Americans’ desire for European weapons, led to the overhunting of beavers in the Northeast. Soon, beavers were extinct in New England, New York, and other areas. With their loss came the loss of beaver ponds, which had served as habitats for fish as well as water sources for deer, moose, and other animals. Furthermore, Europeans introduced pigs, which they allowed to forage in forests and other wildlands. Pigs consumed the foods on which deer and other indigenous species depended, resulting in scarcity of the game native peoples had traditionally hunted.
