It's good when normally non-political (at least, publicly) celebrities like David Letterman come out and attack corporate greed, because I suspect it has more of an impact. Letterman's right, of course - but no one's going to do anything to stop it because you can never really have enough money in your campaign chest:

David Letterman held nothing back last week when he voiced his concerns over fracking, calling the oil companies greedy, he plainly explained to America, “we’re screwed.”

The Late Show host went on to point out the issues with water contamination as a result of fracking, saying, “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.”

Fracking is a controversial drilling method used for extracting natural gas. It has spread throughout the U.S. in recent years, despite growing acknowledgement of the risks involved. It has come under even more press in New York state recently, where activists are currently fight against reports that Governor Andrew Cuomo may allow fracking to take place in several counties.

Letterman joins fellow commedian, host of Late Night, Jimmy Fallon, who also recently discussed fracking on his show. Fallon joined Sean Lennon and Yoko Ono on stage for a song, titled “Don’t frack my mother.”
