Fracking is still a very unproven technology - there are threats of contamination of air and water supplies as well as rural landscapes becoming industrial wastelands. Now, there's the threat of earthquakes from the practices associated with fracking for shale gas.
These are serious issues, for the environment, for public health, and for quality of life. Is fracking worth it? In light of all this, the answer would be no, at least at the present time.
