While scientists have yet to isolate cause and effect, many suspect chemicals used in drilling and hydrofracking (or “fracking”) operations are poisoning animals through the air, water, or soil. Last year, Michelle Bamberger, an Ithaca, New York, veterinarian, and Robert Oswald, a professor of molecular medicine at Cornell’s College of Veterinary Medicine, published the first and only peer-reviewed report to suggest a link between fracking and illness in food animals.
