To my great surprise, I found Gasland (with embed code) on YouTube.
Since the producers of Sicko decided to remove it from the web, I figured that the producers of Gasland would as well. Nevertheless, as you can see, it's embedded below. If, for some reason, the embed does not work, it's also on Netflix streaming, here.
So what is Gasland?
It's a film by Josh Fox, whom you can read more about here.
From the Wiki synopsis of the film here.
Nominated for an Academy Award for Best Documentary in 2011, the film focuses on communities in the United States impacted by natural gas drilling and, specifically, a method of horizontal drilling into shale formations known as slickwater fracking.
Please watch the film either through this embed or on Netflix.
