Science. Evidence. Facts. Do these even matter anymore in U.S. policy? They should – especially when it comes to issues that affect our health and environment, like fracking.
Concerned Health Professionals of New York and my organization, Physicians for Social Responsibility, recently released a remarkable compendium of research on the subject. It summarizes and links to over 1,500 articles and reports and has become the go-to source for activists, health professionals and others seeking to understand fracking.
The new studies we looked at expose serious threats to health, justice, and the climate.
A 2018 study in the Journal of Health Economics, for instance, found that the babies of Pennsylvania mothers living within 1.5 miles of gas wells had increased incidence of low birth weight. Babies with low birth weight (under 5.5 pounds) are more than 20 times more likely to die in infancy than babies with healthy birth weight.
Babies exposed in utero to fracking are likely to face additional challenges throughout their lives. They may suffer long-term neurologic disability, impaired language development and academic success, and increased risk of chronic diseases, including cardiovascular disease and diabetes.
Other researchers are finding that fracking wells and associated infrastructure are disproportionately sited in non-white, indigenous or low-income communities.
A study published this year in Ecological Economics analyzed the socio- demographics of people living near drilling and fracking operations in four high-fracking states: Colorado, Oklahoma, Pennsylvania, and Texas. It found strong evidence that minorities, especially African-Americans, disproportionately live near fracking wells.
They don’t just face disproportionate exposure to toxic emissions, leaks and spills. They also have fewer resources – such as health insurance, medical services, or income security – that would help them protect their health.
But you don’t have to live near wells and pipelines to be at risk. We all face harm from fracking’s impact on the climate.
So-called “natural gas” is 85-95 percent methane, a short-lived but highly potent greenhouse gas. Over its first 20 years in the atmosphere, methane traps about 86 times more heat than carbon dioxide. That 20-year timeframe matters: Scientists tell us that’s about the time we have to slash our greenhouse-gas emissions and begin pulling carbon out of the atmosphere.
Unfortunately, as the research we collected finds, methane-leakage rates from drilling and fracking operations have “greatly exceed” earlier estimates.
Overall, how bad is fracking? The compendium states that “public health risks from unconventional gas and oil extraction are real, the range of adverse environmental impacts wide and the negative economic consequences considerable.”
It concludes: “Our examination of the peer-reviewed medical, public health, biological, earth sciences, and engineering literature uncovered no evidence that fracking can be practiced in a manner that does not threaten human health.”
The logical conclusion is that, for health, justice and a livable world, the time to stop using fracked gas is now.
