The National Parks System killed a female Grizzly Bear with cubs who mauled a hiker in Yellowstone National Park on Friday, August 7 resulting in his death. Protecting cubs is a natural behavoir for female bears, who must defend cubs against other male bears. Her cubs are being sent to the Toldedo, Ohio, Zoo and will never live in the wild again.Tell the NPS they should alter their policies for euthanizing famle Grizzlies with cubs, keeping the family together, and sparing tfemale bears' lives.
