Shale gas development uses slickwater hydraulic fracturing (the kind of fracking that's only about a decade old.) This uses huge amounts of fresh water which by the end of the process has been turned into toxic waste - water now filled with many known carcinogens and chemicals that can affect people's endocrine systems. Air quality is affected because of the thousands of trucks needed for the process, the compressor stations and the Volatile Organic Compounds that escape into the air. Shale gas development turns huge tracts of rural land into industrial zones as thousands of wells cover the area. Once the process has begun it seems impossible to stop - even as the scientific evidence is starting to come in - warning of the dangers to health, the environment and the social fabric of the affected area.
