Teaching Tips
- Fracking is a controversial political subject. This video may be used to introduce a discussion of the tradeoffs between need for increased energy supply and environmental damage and human health impacts that may result from extraction activities.
- Another discussion point could be the question of confidentiality with respect to intellectual property vs public health.
About the Content
- An animated diagram shows how the process of hydraulic fracturing (fracking) is used to extract natural gas.
- The resource also discusses the health and pollution problems that are potentially associated with the process.
- One of the challenges of investigating the possible link between the contaminants and illness is that the gas industry is not required to disclose which chemicals they use in fracking fluids, as that information is protected by intellectual property rights.
- Comments from expert scientist: The video and background essay provide a good basic description of hydraulic fracturing. Attention is given to relevant concerns and benefits, and the science appears to be accurate if somewhat one sided. It appears the resource was produced prior to 2012, based on the facts that the Need to Know television series that it draws from ceased production in 2013 and the essay makes reference to a report to be released in 2012. Understandings of fracking's impacts and industry transparency have both changed in the intervening years. While secrecy related to exact compositions of fracking fluids remains a concern, industry is considerably more likely to reveal fluid composition now than was the case four years ago.
