This is an excellent no-brainer in our opinion, with lots to recommend it (!) including the fact that the oil industry is working hard to limit the EPA's study, hoping to prevent the government from insisting on full disclosure of fracking fluid ingredients. And of course that leaves the industry free to continue to deny responsibility for the obvious ways the process/technique is causing unremediable contamination.
A moratorium pending findings would also prevent any further harm to Life Itself wherever drilling takes place, until it is satisfactorily proven safe... and as drilling spreads across the land, undeniable examples abound.
America's energy independence (the reason we are given for the carte blanche Big Oil has been granted over our environment) seems nearly irrelevant as foreign energy/money barons jockey to buy up leases. Why are we rushing to destroy our vital life sustaining resources for foreign profit before we even know how safe or unsafe hydraulic fracturing actually is!???
Write to your elected officials. Urge them to enact an immediate moratorium on any further drilling activities until we understand the full impact of this process, including disposal of all produced waste, on our public and environmental health, safety and well-being.
