Obviously, the author of this piece favors fracking. Those on the forum may have varying opinions on fracking ... what I found interesting about this article though is the description of what the process really is. Some of you science guys probably already understood this stuff.
Fracking has been around since 1947, according to this article. The process has undergone continual improvement and added safeguards.
It's also interesting to note that the amount of water used for fracking is MUCH less than what is used for ethanol production or soybean diesel, not to mention watering our lawns. If we're really concerned about our water supply, we might do well to eat the corn & use the CNG to run our vehicles.
