Fracking

In this March 25, 2014 photo, perforating tools, used to create fractures in the rock, are lowered into one of six wells during a roughly two-week hydraulic fracturing operation at an Encana Corp. well pad near Mead, Colo. Proponents of hydraulic fracturing point to the economic benefits from vast amounts of formerly inaccessible hydrocarbons that now can be extracted with hydraulic fracturing. Opponents point to potential environmental impacts, with some critics acknowledging that some fracking operations are far cleaner than others. (AP Photo/Brennan Linsley)
