This is an interesting (read: not bashing) article on hydraulic fracturing. For example: "Bob Anthony, Oklahoma Corporation Commissioner, said in an address to the National Association of Regulatory Utility Commissioners in July, 'In my 20-plus years as a commissioner, I can't think of anything that can compare to the all-out assault on hydraulic fracturing by groups that are obviously using it to put a stop to the tapping of America's abundant natural gas supplies.'"
The comments are interesting as well.
