The document discusses the potential economic benefits and environmental concerns of natural gas drilling from the Marcellus Shale formation. It notes that trillions of cubic feet of natural gas could be extracted but raises issues with studies claiming economic gains, as they do not consider costs of environmental damage, impacts on other industries, or health effects. Concerns include risks to water resources from methane contamination, unknown fracking fluid composition, wastewater processing difficulties, and harm to fish and wildlife. It also questions whether most new jobs would go to local communities.
