Some totally obvious things to remember:
Never feed any kind of bear.
Feeding any kind of wild animal can make them habituated to humans, which can be dangerous for the animal and for people, so keep food out of reach and in tight containers.
"Keep in mind that bears have an exceptional sense of smell - seven times more powerful than dogs' - and can detect odors over a mile away," Born Free USA said. "Avoid packing odorous food and use bear-proof, odor-proof containers. Do not leave food or ice chests on decks or in vehicles."
If you're camping, learn how to hang food at least 10 feet off the ground.
Never take a selfie with a bear.
This should really be implied, but, amazingly enough, some people get carried away and feel like they have to snap a close-up with wild animals.
"In the last two years, there has been an increase in people vying for an impressive selfie with animals ranging from seal pups, to bison, to black bears," Adam Roberts, CEO of Born Free USA, said. "This is becoming a dangerous epidemic that is reckless and harmful for both the public and wildlife. No selfie is worth getting killed or condemning an animal to death."
It doesn't mean you can never go outside again. What it does mean is that you should be prepared. Keep your dog (or cat) on a leash, and leave any pungent-smelling food at home, since bears have an acute sense of smell. Most of all, be prepared if you find yourself walking through bear country.
