I think I found scientific proof that skunks are at the top of the food chain. I've seen bears attack wolves, mountain lions, elk and bison and win just about every time. I've never seen a bear successfully take down a skunk including this big guy that got schooled.
Anyone who takes a vacation in bear country should be required to pass a course on what to do and not do before they're allowed to do it. A new video proves this point showing a guy who caught a bear eating candy out of his truck then nearly got eaten trying to scare him away.
In the west, we know that you have to be careful with your food when you're in bear country. A family (not in the west) made the mistake of cooking with the windows open and ended up with a very large uninvited guest.
Since we live in Wyoming, I tend to come across a lot of bear videos and stories. There are few I've seen more inspiring than a rescued bear who had suffered from a badly broken jaw being set free again.
