New Evidence Links Earthquakes to Fracking » EcoWatch.

The evidence linking fracking to earthquakes continues to pile up.

study by seven researchers from California, Colorado, Massachusetts, New Mexico, North Carolina, Ohio and the UK, The Environmental Costs and Benefits of Fracking, said “Unconventional oil and natural gas extraction enabled by horizontal drilling and hydraulic fracturing [fracking] is driving an economic boom with consequences described from ‘revolutionary’ to ‘disastrous.’ The reality lies somewhere in between.”

The studies findings were many, including that fracking “generates income and, done well, can reduce air pollution and even water use compared with other fossil fuels.” But it also found it can reduce investment in renewables and when done carelessly, can release toxic chemicals into the environment. It also agreed: fracking causes earthquakes.
