I watched this quite mesmerised. Nature hates a vacant space. Just my own theory but if you take water out of underground aquifers they must eventually want to refill themselves.
Remember the Bob Newhart sketch about tobacco with the line something like, 'you roll a piece of paper around some dried leaves, put it into your mouth and set fire to it'.
How about this one. You pump water, sand and chemicals into the ground at pressure and gas or petrol comes out. Hehe. Well, not so funny, because apparently it works. It's known as fracking and I consider that to be a great name, although not a great practice.
Mining where you dig things up is one thing, but I find extracting oil, gas and water from underground very disturbing and I very much doubt it is sustainable. So far so good, perhaps. But blowing the earth apart by fracking is surely going down a bad path.
Fracking has been a fracking disaster in some parts of the United States. In spite of promises of cheaper energy bills in England, the general public is fighting against it. In Australia it has caused an unusual alliance between The Greens and farmers. Governments and miners seem to be the only people keen on it, which says to me something to me very clearly.
We are already abusing our planet to a shocking degree. I don't think it is a good idea to be blowing it apart underground. What is to stop these chemicals getting into aquifers? What is to stop a lake or a water storage dam to empty? Do they really know what goes on underground and the connections between things?
