The NATURE program American Buffalo: Spirit of a Nation tells the sad story of how the buffalo nation was destroyed nearly a century ago by greed and uncontrolled hunting — and how a few visionaries are working today to rebuild the once-great bison herds. It offers a remarkable portrait of America’s last significant wild bison herd, made up of a few thousand animals living within Montana’s Yellowstone National Park. And it highlights the efforts of Native American leaders dedicated to bringing back the animal that once gave life to their tribes. “Buffalo have to be there for our culture to exist,” says Fred DuBray, a member of the Cheyenne River Sioux tribe who appears in American Buffalo. “As we bring our herds back to health, we will also bring our people back to health.” Air Date : 1st-Nov-1998  Read More
