Encounters between humans and bears are rising in number. Why? The weather partially explains it. Warmer temps keep bears active longer. But the main reason, all things considered, is more likely to be the increase in the number of bears. Wyoming, for instance, estimates triple the population of grizzlies (about 200 to more than 600) in the Yellowstone ecosystem since the mid-1970s. As Brian DeBolt, the bear management officer for Wyoming Game & Fish, told the Casper Star-Tribune: “. . . if you’ve got more bears, you are going to have more conflicts.” And hunters top the list of possible victims because they walk around quietly, stalking game in bear country, and smelling like dinner.
