WTF is fracking and why are half of my FB friends against it?
gpt
Fracking is a technology that uses water pressure to create fissures (tiny cracks) in shale rock formations that allow oil and gas to flow up the well for collection. (since it is lighter than water)

A lot of people are against fracking because it can potentially destroy the local communities way of life by creating waste water issues, methane seeping into our local water supplies and coming out of our faucet, seismic activities, etc. 

Oil and gas companies are saying that their methods are safe and responsible and that they would work with local authorities to ensure communities aren't affected by this but so far in some communities it has been a big bunch of lies.
