The idea is awareness of surroundings.  In 2008 a woman--a "cheechako", or recent arrival to Alaska from downstate--jogged alongside a stream where coastal brown bears fish for salmon in the spring wearing EARBUDS.  Was about two blocks south of my house, and the woman was badly mauled--she ran up, OBLIVIOUS, on a feeding bear.  Big Brownie doesn't like to share, and WILL let you know via vigorous action on your person.  However, it was the woman's fault.  Ear-buds???  Get real.  And the bear was shot for defending its hard-won meal.  The entire incident was avoidable--the woman needn't have been injured and the bear needn't have been killed.  All that was required was for the woman to BE AWARE of her surroundings.  Unfortunately, once a bear has attacked a human and come away unscathed (which is usually the case), it's usually necessary to shoot the bear.  Predators, being animals, do come to the wrong conclusions after such attacks, making them more likely to repeat its behavior.
