I was for a long time, in favour of ‘fracking’, not least, to prevent the prospect of being held to ransom by Putin (and China). House prices crashing and the catastrophic effects on the environment I perceived as simply scaremongering. Until, that is, I watched a documentary on PBS concerning fracking in the USA. 
The claims of economic benefits to the regions and the low cost of extraction have not been the experience in the United States. The producers make huge profits at the expense of everybody else. 
The Tory record of dealing with multibillion, trans-national companies is not encouraging.
For many years one of my jobs was to monitor the environmental impact of ICI (Wilton) on local air and water pollution. It was no surprise to me that there were no fish in the Tees downriver from Yarm. 
This only changed when the steel works and large parts of ICI effectively closed. The discussion thus becomes ‘the environment or jobs’. 
My experiences would indicate that the very notion of these companies being self monitoring would be as effective as it was concerning the banking institutions. In practice, you simply take enough samples until you get the result you want. Government monitoring does not necessarily offer a solution either. Anybody who has watched he ‘manipulation’ of monitoring by VW among others of air pollution is right to be skeptical.
Just because you believe there is a conspiracy going on, does not necessarily mean that you are paranoid.
