The indians did use all of the buffalo and nothing was wasted. And also the whiteman was disrepectful to the animal. All they used from the buffalo was the hides. There are pictures where there are hundreds of dead carcasses across the plains. I also know that the indians did sneak up on the buffalo using buffalo pelts and did get them running towards cliffs. Also remember too that maybe they didnt use all the meat might have been because they didnt have refridgerators.
They also used to sneak up on the buffalo and kill them with bows and spears. To me that is amazing. The fact that they could hit a buffalo running while they are on the back of a horse and still get it with a bow...........incredible if you ask me.
