It's amazing at how good we humans are at destroying things.

The American buffalo, is a North American species of bison that once roamed the grasslands of North America in massive herds. Their range once roughly comprised a triangle between the Great Bear Lake in Canada's far northwest, south to the Mexican states of Durango and Nuevo León, and east along the western boundary of the Appalachian Mountains. Due to commercial hunting and slaughter in the 19th century, the bison nearly went extinct and is today restricted to a few national parks and other reserves.
