The nonprofit group American Rivers recently named the Upper Delaware River Valley one of the nation's most endangered rivers because of the threat to the water supply posed by hydraulic fracturing, or fracking, to obtain natural gas. Yale Environment 360, which in my opinion is one of the best environmental news sources anywhere, did a fairly in-depth article on the risks of obtaining natural gas from shale by fracking. We should all be very, very concerned, as so many have pointed out. Our country's fossil-fuel-centric energy policy is disastrous, from oil drilling to fracking to mountaintop removal coal mining. I despair for the world we're leaving our children.
