There seems some conjecture around at the moment about the extraction of gas from farmlands whilst running the potential of polluting the underground aquifers once damaged the ramifications are immense on the production of crops. It also seems that the political consensus is divided once again , is the opposition really opposing it based on ethical grounds or is it another way of Just being the opposition ? either way I just do not trust the processes in place when the consequences can be so dire. On lighter note I hear there is a process called a horizontal "fracking" I would assume it can also be done in other positions as well.
