I've seen people carelessly throw away their garbage right next to garbage bins, because they couldn't be bothered to get a little closer or aim.
The bear has more determination, because it has an incentive to get to the tasty, high calorie food that doesn't require the energy expenditure of chasing it down and tearing it apart. Throwing away garbage into a designated container on the other hand is a chore that some people believe they can skip, because they are the sole protagonists in their own stupid little world.
