Oh, well...
I know I'll be downvoted to hell and back, but:
- Shales contain lots of nasty chemicals -e.g. benzene, formaldehyde, ... -, and the water used for fracking also includes a chemical payload.
- The process objective is to create permanent fractures in the shale, which in normal conditions is impermeable and very good at keeping its nasty chemicals from entering the ecosystem. They do this by adding sand to the fracking fluid, sand that will get stuck in the fractures keeping them open.
- Even if they stop the injection process, water from natural sources -like rain- will still extract these chemical compounds from the rock, and it will do so for many years.
- There is no fracking way you can prevent this process from contaminating the water table. The extent, severity and future consequences of such contamination are still being discussed, by people who know much more about these matters than you and me and the general public.
If the British public is aware of these facts and still supports fracking, I would suggest two possible explanations:
- As other fellow commentards have suggested first, urbanites give their water supply for granted, and don't give a shit about what happens in the countryside. Said urbanites would be totally wrong, of course, as all their water comes from wells and reservoirs placed in the countryside, but hey, ignorance is bliss :)
- Or people are looking for some magic 'trick' that will improve the Economy and will bring back 'The Good Old Days'. Sorry to inform you, the system is not designed for that. It will make a few extremely rich, it will provide jobs for some more for a while, and will leave behind a ton of shit to clean afterwards. And you or your children will have to foot the cleaning bill.
Disclaimer: I don't consider myself a greenie. I don't agree with all of their arguments. I don't like the way they carry out some of their protests.
