There are now more than 2,000 peer-reviewed studies and investigations on the impacts of fracking, the vast majority of which either confirm the damage done by fracking, or raise threatening new issues. If there were a similar number of studies showing that fracking did not threaten public health, contaminate water, pollute the air, or worsen climate change, we would know about them, since the gas industry would have touted them far and wide.
Reviewers of all the known public health studies stated they could see no way that fracking could be done safely, and that it is especially hazardous to infants and children.
