Josh Fox's controversial film "Gasland" put hydraulic fracking, or "hydrofracking," in the public eye. But for a group of NYU students, it presented an opportunity to take action against the controversial method of energy extraction.
Natural gas trapped one to two miles below the surface of the earth is released and brought to the surface with the use of a mixture of water, sand and chemicals. Under extreme pressure, drills force "frack" fluid up to 8,000 feet into the ground until small explosions occur and the gases are released.
