One of my favorite films about aliens invading the earth is John Carpenter’s They Live. The aliens strip the earth of its resources and accelerate global climate change to change earth’s environment to that of their home planet. Some humans collaborate with the aliens and are rewarded for their betrayal with money and positions of power.
My all time favorite film about aliens transforming the planet isn't science fiction. It's the recent documentary Gasland.
The film is about what happens to the people, communities, and the environment, when natural gas is obtained by a stimulation method known as hydraulic fracturing.
Hydraulic fracturing or “fracking” is a means of natural gas extraction employed in deep natural gas well drilling. Once a well is drilled, millions of gallons of water, sand, and a mixture of 596 chemicals, many of them toxic, are injected under high pressure, into the well. The pressure fractures the shale and props open fissures that enable natural gas to flow more freely out of the well.
Generally 1-8 million gallons of water may be used to frack a well. A well may be fracked up to 18 times.
For each frack, 80-300 tons of chemicals may be used. Presently, the natural gas industry does not have to disclose the chemicals used, but scientists have identified volatile organic compounds such as benzene, toluene, ethylbenzene and xylene. Many of the chemicals in the proprietary fracking fluids are carcinogens, and once they are forced into the shale, not all come back home.
