So what alarmist hyper-environmentalist news stories are we to believe? Last time I checked, we had environmentalists screaming that fracking thousands of feet down leaks chemicals (sand, light hydrocarbons) through thousands of feet of permeable geological layers. If these layers are so permeable and the alarmists are telling the trough, how come it takes `thousands` of years to recharge the aquifers?

The act of fracking, or fracturing, creates many tiny cracks.

Here's a thought experiment: Stick your head under a bucket of tightly packed soil (mostly clay) in a bottomless bucket and fill it up.

Now try the same thing after you use a spade on the soil in the bucket for a few minutes.

Get the picture?

Let's hope he actually tries your experiment - and without a spotter.

Rather than telling other people to "grow up," how about focusing on their actual arguments? That's something you didn't really do to begin with.

Well I would, had there been any arguments present. There weren't. It was all pure opinion. It is not "a fact" that walled gardens are bad - it's an opinion. You should really learn the difference.
