I think fracking, which just means fracturing the rocks underground, is bound to cause massive leaks of methane into the atmosphere. Just see the trailers for the movie Gasland.
And the massive amount of oil and gas that they are finding, WOW.

"Proved reserves -- which now stand at the equivalent of 12 years of gas consumption and 3.3 years of oil demand -- represent energy supplies that are extensively charted out and could be tapped under current market conditions. Total recoverable reserves, however, can be far higher."
woopie doo! HURAH for technology.
