Since the requirement in the US for the use of bear canisters (plastic cylinders that bears cannot open) for food storage the problem has gotten a lot better. Bears used to be more aggressive once they learned that people have food. Now in general they have learned that the food cannot be accessed and tend to stay away; though some have learned that if you scare the people when the canister is open they can get the food out.
