This 2010 documentary is all about “fracking,” the increasingly common term for hydraulic fracturing, the practice of forcibly extracting natural gas from deep underground. There’s much debate about the safety and possible side effects of this method of energy cultivation, and some of that debate started with this film. When you see a local resident, whose ground water has been contaminated by local fracking efforts, turn on his tap water, light a match and have the water burst into flames, it’s fracking incredible.
