As you ponder the fact that the epicenter of the earthquake was ~8,000 miles away from the Sulzberger Ice Shelf in Antarctica, I hope you'll start to better understand why I have been opposed to hydrofracturing a layer of bedrock less than 2 miles from Pennsylvania's freshwater aquifers and surface waters.
It's all connected, folks. Cause and effect. If you truly believe that fracturing a layer of bedrock at pressures much greater than those existing naturally at that same depth will not cause water and chemicals - under higher pressure - to migrate toward areas of lesser pressure, then you need to study up just a little and/or get off the natural gas industry's payroll.
Recently, Tom Shepstone of the EID-NMI claimed we "radicals" were being painted into a corner.
Nothing could be further from the truth...except whatever the natural gas industry has to say about hydrofracturing.
