PHILADELPHIA — Gov. Tom Corbett is attacking anti-drilling activists as the "unreasoning opposition" who accept the nation can land a space vehicle on Mars but don't believe energy companies can safely harvest gas a mile under the earth's surface.
Corbett spoke Thursday at a Marcellus Shale industry conference in Philadelphia.
He says Pennsylvania is reaping an economic bounty from natural gas despite "predictions of disaster and the fearful warnings from people with no understanding of the industry."
Activists opposed to the extraction technique known as hydraulic fracturing are planning their own slate of events outside the Pennsylvania Convention Center. Protesters portray shale-gas drilling as bad for the environment and public health.
