BOZEMAN, Mont. -- Casey Anderson knows Grizzly Bears well. He raised Brutus, a popular 800 pound bear from birth. The animal even accompanies him on his new show Expedition Wild, which aires on National Geographic Wild.

In light of a recent Grizzly attack in which a Michigan man was killed, Anderson has been busy talking on talk shows, news programs hoping to educate people about Grizzlies and their behavior.

Two people have been killed in the Yellowstone area this year by Grizzlies.

It is a stunning number of deaths, given in the previous 100 years, six people were reported killed by Grizzly Bears in the region.

“It’s been a tragic year for Grizzly Bears in the Yellowstone ecosystem,” Anderson said.

It is very difficult to pinpoint a specific cause of why bears attack. Mostly Anderson thinks it has to do with bears competing more frequently for their food source.

Overall he said, bear and human populations are going up in places like campgrounds and area forests. “It’s a natural pinch,” he said. “They’re interacting with humans more than they ever would before.”

But Anderson wants people to know, there are simple things humans can do to lower the chance that a Grizzly will attack. The best defenses are pepper spray, and portable electric fences.

And although those two elements alone can dramatically reduce the chance that a Grizzly will attack, Anderson points out that no method is fool proof. Especially in campgrounds where it is impossible to know how the previous group took care of an area.

“Even though those people were doing very good, and storing their food properly, you never know what the people before them did. So you might pay the price for someone elses bad habits. So that’s always something to keep in mind,” Anderson said.

But overall Anderson thinks these methods are very helpful in reducing incidences. “Do yourself a favor, do the bears a favor. Adapt and do these things,” he said.
