Really, this is a toxic waste issue. It's not an energy policy or a natural ,gas, policy, so the two things are different and are separate. The reality is that fracking is not the only way to get natural ,gas,, although sometimes this conversation makes it sound as if it is, and you know, that's the answer I have. Bottom line is, we do buy natural ,gas,.
