Dr. Sandra Steingraber and Dr. Kathleen Nolan work with Concerned Health Professionals of New York, a group of scientists opposed to fracking. Steingraber and Nolan brought with them a compendium of scientific studies relating to fracking that has recently been translated into Spanish. It includes articles looking at health and environmental effects, as well the social impacts on communities in which fracking takes place. The Indy sat down with the North Americans to talk about the conference and the fracking debate in the US and Argentina. What do you say to people who think that fracking will bring economic benefits to communities?
