The Washington Post reports on some new research coming out of the DC metro area that suggests that geese, bears, deer, livestock, and other wildlife are major contributors to rising levels of bacteria in the Potomac and Anacostia Rivers.

The article contends that the high percentages of bacteria are the result of “unnaturally high populations of deer, geese and raccoons living in modern suburbs and depositing their waste there.”
Of course one of the reasons that there are “unnaturally high populations” is because low-intensity suburban sprawl destroys prevailing ecological systems and certain species are better able to adapt than others. Curiously, these species are the ones tagged by the article as the “wildlife” responsible for the high levels of pollution.
Thus, it doesn’t seem entirely accurate to talk of “wildlife” waste as something emanating separately from human activities. In fact, high populations of one of the more polluting species–non-migratory Canadian geese–are apparently decendents of geese brought to the mid-Atlantic region as hunting decoys.
The distinctions between “wildlife” and human behavior are not quite so clear.
