He’s just given this bear the idea that humans = food or reinforced this if the bear has been fed before. What an idiot. The next person the bear encounters who does not have food when the bear expects it, could be in trouble. Also, this irresponsible behavior by humans often consigns the bears they habituate to death.

Above is a “bear cam” from Alaska. They are safe to watch from the raised boardwalks, and even safer on the internet! (look at all those salmon!).
I’ve been to a few of those places (in person) and never saw anyone trying to feed the bears.
