In this October 6, 2014 photo provided by the Douglas County Sheriff's Office, a black bear tears apart a car interior while trying to escape the vehicle after foraging for food inside, in Castle Pines, Colo. Bears are common in the area, drawn to berries that are plentiful after a wet year.

I've seen lots of bears just none that were trapped like that”, warden Jesse Ashton said. Ashton and the Milltown Fire Department were able to cut a window into the tree, freeing the cubs who then ran off into the woods unharmed. (Photo by Wisconsin DNR via KAR)

Bua Noi (Little Lotus), 28, a gorilla, leans on the bars of her cage on World Animal Day, on the top floor of a old shopping center, at Pata Zoo in Bangkok, Thailand, 04 October 2014. Bua Noi has been housed at the zoo since she was bought from a zoo in Germany to Thailand in 1988, living on concrete behind bars and a glass wall, without any green living vegetation inside. A campaign has collected more than 35,000 signatures to try and exert pressure to have the gorilla moved to more natural surroundings, calling on the end of such caged zoos in favor of natural wildlife areas. Declared in 1931 to highlight the plight of endangered species such as the gorilla, World Animal Day falls on the feast day of St Francis of Assisi, the patron saint of animals. This year it is timed with a report from World Wildlife Fund revealing wildlife across the world has dropped by more than 50 percent in 40 years, as humans continue to show their over consumption and destruction of other species and their habitats.
