Britain’s Cuadrilla Starts Fracking For Gas After Seven-Year Pause

British shale gas company Cuadrilla has started fracking for natural gas in northwest England, seven years after the practice was halted in Britain for causing earth tremors, Reuters reported on Oct. 15. Environmental groups strongly oppose the practice of hydraulic fracturing, or fracking, which involves extracting gas from rocks by breaking them up with water and chemicals at high pressure.
