I never heard of fracking before today. My husband heard them talking about it on the news this morning. I wasn’t able to catch a lot about it, being that it was that time in the morning when too many other things are going on. Then on my grocery shopping trip this morning, the owner of the organic food store asked me if I’d heard of it and said he might get a rally going about it.
I looked up fracking and the most relevant answer (on Wikipedia) was:
“Fracking (also “fracing”) may refer to hydraulic fracturing of oil or gas wells, in which a slurry of sand and chemicals is injected into the rock formation at high pressure. The fracking fluid weakens and fractures the surrounding rock, making it more permeable and thus easier to pump the oil or gas from the well. However, use of fracking chemicals[fn 1] have been blamed for environmental pollution and serious illness such as cancer.“.
