Here we go again. Another example of Hollywood trying to preach ignorance at us. It is pretty obvious that they were influenced by that bit of Oscar nominated propaganda called GasLand when they wrote this episode. They even repeated a number of the lies perpetrated by that movie. In the episode, they claim that natural gas exploration has not been subject to specific environmental regulations since 2005. This claim is based on a lie in GasLand in which they claimed that Dick Chaney forced legislation through in that year to exempt the natural gas industry from this law. In reality, these industries ARE regulated under all of the regulations cited. The second lie is the claim that the fracking fluid is this mix of toxic chemicals. It is not. If you want to know the truth about what is actually involved in fracking, then you might want to check out the following source. Its assertions are pretty well documented. http://www.energyindepth.org/2010/06/debunking-gasland/
