Should fracking be banned? Why or why not?
Introduction
On Tuesday, November 4, 2014 three counties in California will decide by ballot whether or not to ban hydraulic fracturing, otherwise known as “fracking.” It’s steeped in controversy, from the amount of water it uses to how and where that water–and added chemicals–are eventually disposed. In California, fracking is used mainly for the production of oil, but in other parts of the country it is used to mine natural gas.
Fracking is one part of the process that brings an oil or gas well into production; that is, to allow oil and gas to be released from rocks underground and brought to the surface. During fracking, water, along with sand and chemicals, is injected into a well that may extend hundreds or thousands of feet beneath the surface. Pumping this watery mixture into the ground at high pressure causes cracks, or fractures, in the rocks. The sand in the mixture works to hold the cracks open, allowing the oil or gas to escape. Then, the fluid returns to the surface, bringing with it the sought-after oil, often additional groundwater, and other materials, such as salts and heavy metals. Oil is separated from the “produced” water, then the water is injected back deep into the rocks in a disposal well.
Hydraulic fracturing is a way to extract oil and gas trapped underground for use in energy production. Proponents claim that it is a safe way to access these natural resources to help meet the energy needs of the U.S. and allay the costs associated with foreign oil.
Opponents think that we should be moving away from dependence on fossil fuels and instead put money and resources towards developing renewable energy sources. They are also worried about lasting effects of fracking, such as the use of massive amounts of freshwater in the process, possible groundwater contamination from wastewater disposal and other potential pollution.
What do you think? Should fracking be banned in California? In the United States? Why or why not?

We encourage students to reply to other people’s tweets to foster more of a conversation. Also, if students tweet their personal opinions, ask them to support their ideas with links to interesting/credible articles online (adding a nice research component) or retweet other people’s ideas that they agree/disagree/find amusing. We also value student-produced media linked to their tweets. You can visit our video tutorials that showcase how to use several web-based production tools. Of course, do as you can… and any contribution is most welcomed.
