The controversy over hydraulic fracturing to tap natural gas can be highly technical and contentious. Some students at New York University put this catchy music video together to highlight the concerns that have been raised about "fracking," as it's commonly known.
Of course, it's just one side, and there's debate over how "new" fracking is, much less how big a threat. Check out the comments posted with the video. I happen to agree with the observation it sounds like something from the HBO series "Flight of the Conchords." More seriously, feel free to go here to get the admittedly less musical point of view from Chief Oil & Gas, one of the companies drilling in Pennsylvania and seeking approval to drill here in Maryland.
