We were camping in a pop up with the kids in Rocky Mountain National Park at Glacier Basin. Every afternoon a park ranger would come by following a bear which visited the dishwashing stations that were outside the toilets. We asked him how it was going, and he said if people would just flush the sinks (they were like big toilets and swooshed debris down, the bear would eventually get bored and stop coming. The smells were still there (smells are EVERYWHERE to a bear), but no reward would discourage them. The ranger was there to keep the bear from being harassed.
Food-habituated wild animals frequently do end up dead. There was a coyote in Death Valley who learned if he stood in the road humans would throw him food and say “Oh, how cute!” He was killed by a car a few years back. Burros get killed by cars who don’t see them when they come begging along the road. The marmots around Old Faithful in Yellowstone lose their hair due to malnutrition because humans feed them our food; they die due to environmental conditions while naked.
“A fed bear is a dead bear.” And so many other animals.
