Scott Goldsmith: “This is a truck-driving class in Canonsburg, Pennsylvania, at a technical school. This woman is on video, saying, ‘After I graduate from this class, I will not work for the gas companies after knowing what they do. This was my introduction to horizontal hydraulic fracturing, a.k.a. fracking. After doing extensive research on the subject, I was shocked to find out how horrible it was for our land, water and air. I was saddened by how the gas companies try to hide the damage they are doing not only to the environment but also to the communities they polarize… As fracking increases around the world, an increase in truck driving is one of many ways the extraction of natural gas from shale leads to extensive and growing climate change problem.”
