The benefits of tracking far outweigh the environmental costs. Environmental impacts of fracking are widely overblown with cherry picked examples being used to represent the franking industry as a whole. It's time for some honesty in this debate. When push comes to shove, consumers vote with their pocketbooks. To that and tracking must continue.
There have been numerous evidence that fracking has caused disruption in the water table by infusing carcinogens. Incidents of cancer in several states has increased. There have even been earthquake like incidents in West Virginia. These should be enough to stop fracking from continuing but there's too much money to be made. The environment is suffering and so are the inhabitants.
No, the benefits of fracking does not outweigh the environmental cost because climate change has become a major issue in world politics. The year of 2015 was one of the hottest years ever recorded. Fracking severely damages the environment and there are other emerging sources of natural energy such as wind and solar.
No, fracking is not an acceptable means to acquire cheap energy. We are at a point in time where energy markets are at an all time low due to extreme supply of oil and natural gas. There is also not nearly enough evidence acquired over time to accurately determine the long term impact of fracking on our planet.
