Watch David Letterman's two-minute rant above on the "greedy oil and gas companies of this country" who are trying "to squeeze every little last ounce of oil and gas out of previously pumped wells by injecting the substrata of our planet with highly toxic, carcinogenic chemicals which seep into the aquifer and hence into the drinking water of Americans. The Delaware Water Gap has been ruined, the Hudson Valley has been ruined, most of Pennsylvania has been ruined; Virginia, West Virginia has been ruined; Colorado has been ruined; New Mexico has been ruined. They're poisoning our drinking water. Ladies and gentlemen, we're screwed."
Letterman starts by saying "I'm not smart enough to understand fracking." He should have stopped there, it was the only intelligent and truthful part of his deranged diatribe.
