Biotic Impacts of Fracking

by Emil Morhardt

How does shale-bed energy development, including hydraulic fracturing, affect ecology? There have been a number of studies looking into this, and a new review paper by Sara Souther at the University of Wisconsin and seven colleagues at a diverse array of other institutions summarizes the current knowledge and where the gaps are in it. Their legitimate fear is that much damage will be done before much is known about the issues, and there is plenty of experience with other rapid industrial development to warrant concern. As an example, consider the damming of nearly all the rivers on both the east and west coasts of the US with little attention paid to the consequences for salmon.

The big issues they identify are subsurface and surface water contamination by fracking Continue reading
