When I lived in Montana people hated this commercial.

OK

It's interesting how nowadays the commercial is often criticized for a very different reason, either because it's accused of playing into the "vanishing Indian" narrative (in which indigenous peoples are portrayed as belonging to a long-gone past and their "remnants" soon doomed to disappear), or because the campaign was financed by corporations that wanted to shift the onus of pollution on individual citizens littering rather than corporate entities responsible for a great deal of pollutants.

But I've seen people from back then say that the ad campaign really did help reduce litter and make people more conscious of environmental problems, even if the focus on individual littering was too narrow.
