Allowing a bear to obtain human food or garbage, even once, may cause it to seek out more human food. Eventually, if the bear becomes a threat to human safety, it will be killed. In order to prevent any such situation, a lot of national parks require all food to be stored in bear proof containers while you're out in the wilderness. Small, 3 gallon plastic containers are good for hikers. Bigger steel drums usually are used on longer canoe trips.
