The Native Americans were badly affected by westward expansion as they faced the loss of a major food source due to buffalo hunting.
Explanation:
After the gradual westward expansion that occurred over a few years, the new white settlers began hunting buffaloes for their thick hides.
Within a few years of hunting carried out by the white settlers, a large population of the buffaloes disappeared.
These populations of buffaloes served as a source of food for the Native Americans which were no longer available due to extensive hunting carried out by the white settlers.
