I know there is a problem in New Jersey with over population of Black Bears (no hunting allowed) and there have been several attacks on people. Here are 2 articles inferring a trend of aggressiveness towards humans is on the rise.
One is from an official from the state of NJ and the other has a larger national perspective.

Even though there are more pit bull attacks than bear attacks I do not want to be the victim of either!!
