Sound wildlife management is needed since humans have already altered the landscape too much to completely coexist peacefully. For example in California coyotes wouldn't be out of control if the state would allow other forms of trapping besides cage traps.
Just to be clear it is hunters/fishermen dollars that pay to maintain healthy populations of these animals for all to enjoy. Snapping photos only helps the photographer get a warm fuzzy feeling.
By the way I live in NJ and work in Philadelphia. I know plenty about cities, traffic etc..
