If you live over or near the pink on the map, you’re near a potential fracking site. Fracking, short for hydraulic fracturing, uses water to extract natural gas from solid rock.

News You Can Use

Our insatiable hunger for fossil fuels is being increasingly fed with natural gas. Using natural gas has a lot of advantages. Natural gas burns more cleanly than petroleum. There is a lot of it. Rather than being mostly in the Middle East, tremendous reserves are located in the United States and Canada. This is very desirable politically. Advances in technology – fracking - have made it easier than ever to get the gas out of the ground. For these and other reasons, the United States, Canada and other nations are experiencing a natural gas boom.
