natural gas is "clean" only in contrast to coal - just as a bacon cheeseburger can be regarded as healthful compared with a double bacon cheeseburger. Per kilowatt of electricity generated, gas releases
55 percent as much carbon as coal. And gas drilling poses a growing threat to our water supplies.
The investigative news organization ProPublica has
documented thousands of cases of surface and groundwater contamination caused by drilling in conventional and shale deposits in six states.
In Pennsylvania, which shares the vast, gas-laden Marcellus shale formation with four other states, drilling is expected to generate
19 million gallons of waste water daily by 2011, according to the state's Department of Environmental Protection. The water, which carries both natural and human-made toxins and is up to five times as salty as sea water, puts a heavy burden on water treatment plants. New York residents are working to
prevent drilling in the Marcellus formation, because its shale and gas underlie the groundwater source for millions of people downstate.
Meanwhile, major fracturing-fluid manufacturers refuse to reveal their products' ingredients. (Industry leader Halliburton maintains that to compel it to list the chemicals in its products would be an "
unconstitutional taking" of its intellectual property.) Investigators have managed to
identify many of compounds used in fluids, and many are
toxic. Some, including benzene, formaldehyde, 1,4-dioxane, ethylene dioxide and nickel sulfate, are confirmed carcinogens.
The above info came from a piece written by Stan Cox and published by Common Dreams. Natural gas may cut our depedence on foriegn oil in the short term, but does nothing to cut carbon emissions in the longer term, break us of our fossil fuel dependance, or move us towards other alternatives-it will simply keep us marching towards our extinction.
