There's only one thing for humans to do when bears start getting smarter, and that's to get smarter ourselves.

At North Carolina's Grandfather Mountain State Park, black bears have reportedly become so "active" that park rangers had no choice but to issue a warning to visitors on Facebook last week.

Apparently, one camper learned the hard way that the bears have a new skill when one managed to outsmart his "bear hang," an age-old bear-proofing trick that keeps food safe by hanging it from a tree.

That's right. The wily creatures have finally solved the puzzle, and now even crumbs are at risk.

"A bear got their food down," the Grandfather Mountain State Park wrote alongside a photo of a mama black bear and her two cubs (below). "Bears have a sense of smell seven times more powerful than a blood hound's. With a nose like that, you can see why it's so important to be meticulous about food storage."

The park went on to share a few safety tips, and reminded visitors never to approach the bears, or run from them.

"If a bear approaches, move away slowly; do not run," officials advise. "If necessary, attempt to scare the animal away with loud shouts, by banging pans together, or throwing rocks and sticks at it."

But most importantly, be sure to show them respect.

"Seeing a bear in its wild, natural environment is a very special experience; and is not an imminent risk — as long as you keep your distance, act responsibly," the post concludes.
