Science Matters: What's the fracking problem with natural gas?

Hydraulic fracturing requires massive amounts of water. Disposing of the toxic wastewater , as well as accidental spills, can contaminate drinking water and harm human health. And pumping wastewater into the ground can further increase earthquake risk. Gas leakage also leads to problems, even causing tap water to become flammable! In some cases, flaming tap water is the result of methane leaks from fracking. And methane is a far more potent greenhouse gas than carbon dioxide! Those are all serious cause for concern — but even they don't pose the greatest threat from fracking. The biggest issue is that it's just one more way to continue our destructive addiction to fossil fuels. As easily accessible oil, gas, and coal reserves become depleted, corporations have increasingly looked to "unconventional" sources, such as those in the tar sands or under deep water, or embedded i...
