Will the boom in natural gas drilling contaminate America's water supply? In the debate over energy resources, natural gas is often considered a "lesser-of-evils". While it does release some greenhouse gases, natural gas burns cleaner than coal and oil, and is in plentiful supply—parts of the U.S., including Pennsylvania, sit above some of the largest natural gas reserves on Earth. But a new boom in natural gas drilling, a process called "fracking", raises concerns about health and environmental risks. See this award-winning documentary on the surprising consequences of natural gas drilling followed by a panel discussion including Representative Josh Shapiro.
