The frackers keep claiming that they have been engaging in hydraulic fracturing for 60 years.
This is as silly as saying pea shooters are the same as assault rifles. Yes, a projectile comes out of a tube in both cases, but the power and effects are totally different. The fracking that they did 60 years ago was very shallow and they did not have the kinds of pumps they use now. The modern pumps are as strong as a commercial passenger jet engine and they can use up to 6 of these monsters on each well.
They also didn't use the same chemicals as they have now and never even attempted to do what they do now - smash to smithereens whole strata of solid rock. That is what they do. Can you imagine the power needed to do that? The earth is not a solid thing. there are cracks and fissures and underground streams and even lakes down there, and all that pressure is sending shocks and chemicals to where none of us knows.
Not even the geologists, engineers and drillers have even a faint idea of what effects this fracking is having down there thousands of feet in the earth. We only know, from plenty of evidence, that it poisons water, land, people, animals, crops and other vegetation. It also cause earthquakes and that should tell us just how powerful the stresses are from this process.
They do not care what damage they do, because the initial licence holders get out quickly. As soon as the first strong flows start, they sell off parts of the licence and get mug investors to put up money. Then they go off before the stream slows down and all the ecological problems start becoming obvious.
They then go and do the same thing to some other unfortunate communities.
