You left out the matrix on the other side of the equation. What is the cost of not fracking? Very, very debatable. On a case by case evaluation, the risk from any single fracking well seems much higher than the risk of not using that well. On the aggregate, the calculation may be different. But again, it is all very arguable. In an argument of this consequence, the side that says, "That's secret information" should lose.
