Drilling for natural gas or geothermal entergy can be doing more harm than good if the drilling causes increased seismic activities. From an article in the New York Times about geothermal drilling in California, "drilling near fault lines can cause increased seismic activity." Foxnews.com reported in an article that "fracking" or hydraulic fracturing in which water is injected into the ground at high pressure to fracture rock and release the natural gas in it could be the cause of the earthquake swarm in Arkansas.
Many geologists and earthquake experts disagree on to what extent drilling is having on the seismic activity on these areas. How do we know where to draw the line between the search of alternative fuels due to the cost and limitations of fossil fuels and preserving nature and our Earth as we know it.
