My last post was about looking into alternative energy. This post will be focusing on a specific type of alternative energy, fracking, or mining the ground for natural gas. Some people, including those in the Switch documentary, hail this technology as clean energy and a promising industry, but the damage done by fracking may far outweigh the limits.  I watched yet another documentary I highly recommend called Gasland which studies the issue in depth.
Typically, fracking is done out in poor rural communities, which makes it difficult for the people to be heard when they complain about the way fracking has polluted their town. What kind of pollution you might ask? Well, the natural gas can sometimes leak into a resident's water supply, which of course makes it unsafe to drink. Enough pollution can lead to incidents like the ones shown in these videos:
