Health and Environmental Experts:Follow the Precautionary Principle on Natural Gas from the Marcellus Shale Since 2007, Pennsylvania has witnessed a dramatic increase in unconventional development of natural gas from the Marcellus shale formation using high-volume hydraulic fracturing, also called “fracking” or “fracing”. Hydraulic fracturing uses known toxins and … [Read more...] about Precautionary Principle for Marcellus Shale

Info from Wikipedia: The Marcellus Formation is a black shale formation found throughout the Allegheny Plateau, running across the Southern Tier and Finger Lakes regions of New York, in northern and western Pennsylvania, eastern Ohio, through western Maryland, and throughout most of West Virginia extending across the state line into extreme western Virginia. The Marcellus … [Read more...] about Marcellus Shale – Background
In this section, we focus on the environmental impacts of drilling for natural gas in the Marcellus Shale formations using the fracking or fracturing method (some background info is given on the Marcellus Shale page). Thoughts about use of the resultant natural gas itself can be found in the Energy section in the piece by Dennis Lieb: "The Drive-in Utopia is Closed". The … [Read more...] about Impacts of drilling in Marcellus Shale
Most experts now agree that 'Hubbert's Peak' — the point at which world oil production starts to decline—has either already passed or will occur within the next year or so. Some of the world's largest fields, in Saudi Arabia, Mexico, and Kuwait, have already peaked. (U.S. production peaked 30 years ago.) Even as oil and gas production are declining, consumption continues at … [Read more...] about What is ‘Peak Oil’?
Mountaintop Removal mining is a technique used to remove coal that is found in relatively thin layers. The technique is basically to blast the top of the mountain and push the rubble off into the valleys to expose the coal seam, which is then trucked away. Then another round of blasting takes them down to the next layer, and so on. The practice uses far fewer miners than … [Read more...] about MountainTop Removal mining (MTR)
