Not blaming the govt, saying this is exactly a situation where govt can make it right. The market will develop and field the tech, and the govt will make sure the tech doesn't kill us. Think about cars....crazy unsafe things that kill oodles of us. As a people, we have decided that having cars is better than not, so the govt steps in and enforces safety rules and licensing. In analogy, the documentaries in the OP are like the scare videos they show in drivers ed. You still get a license and drive. IMO, I suspect that fracking **can** be done at scale with far less environmental impact than lots of other things humans do, like agriculture or building parking lots, and if part of a climate change mitigation strategy, it can be a net positive. It will only be done that way if regulated as part of a sensible public policy plan.
