Saying that fracking "doesn't comprise wastewater injection" seems a bit like saying that nourishing/hydrating ourselves does not "comprise" visiting the bathroom. While technically accurate, it is a bit disingenuous. Just out of curiosity, what percentage of fracking sites use some alternate means of dealing with wastewater other than injection?

And lest you forget your previous education on this matter, the fracking process does indeed result in earthquakes.
