Enlighten me!

Would you guys care to share any info on fracking you may have? I have not researched it one bit. It's become the same as drugs or abortion, love it or hate it and I know nothing other than the slick commercials on tv.

Are the chemicals they use safe if they hit the water table? And how about the earthquakes, just rumors? Any ties there - or nobody knows yet?

On another note, I find it kind of amazing we use this technology to extract the last molecules of oil, which in some cases we sell, the US is an oil exporter, while we import from many places including the middle east. We sell ours to buy theirs, one the surface it makes no sense to me, anyway now I'm rambling...
