Answer:
D
Explanation:
The species' dramatic decline was the result of habitat loss due to the expansion of ranching and farming in western North America, industrial-scale hunting practiced by non-indigenous hunters, increased indigenous hunting pressure due to non-indigenous demand for bison hides and meat, and cases of deliberate policy by settler governments to destroy the food source of the native Indian peoples during times of conflict. The buffalo hunters paid the railroad to ship the hides of the buffalos they killed. The sale of the buffalo hides helped to pay for the cost of building the railroads. The Buffalo hunters, feed the workers, helped pay for the construction of the railroads, and destroyed the power of the plains Indians.
