"More than 100 physicians urged the Obama administration on Thursday not to approve the construction of liquefied natural gas export terminals until more is known about the health effects of hydraulic fracturing, the drilling process that has opened the way for a big increase in domestic gas production."

"A group called Physicians, Scientists and Engineers for Healthy Energy, which conducts research into unconventional natural gas production, organized a petition arguing that exports of natural gas would increase such domestic drilling, known as fracking, exposing more people to chemicals that might damage their health.

The petition, signed by 107 doctors, public health experts, environmental scientists, and academics, cited a growing number of anecdotal reports associating fracking with adverse health risks through human exposure to water, air and soil."
