Good story, they don't die easily, not comparable to a human.
Electric fencing generally works really well. I occasionally get a request for it from campers used to down south bear country. Not enough problems here to carry it. Bears are smart and persistent. I know an outfitter with some fly-in cabins, used to have bear break-ins every year. Put up an electric fence, no problems until the year a tree fell across the line. The bears must have just kept checking until it was OK again....
