Fracking, or hydraulic fracturing, is a controversial process for extracting natural gas from shale. Critics of fracking question the environmental and health effects of pumping thousands of gallons of water and chemicals underground.
Public hearings over hydraulic fracturing or "fracking" brought hundreds of protesters to Binghamton, N.Y., Monday, carrying signs and shouting slogans either opposing or favoring expansion of the controversial process for extracting natural gas from shale.
