A couple of days ago in the US the state of Oklahoma experienced an earthquake, the biggest in its recorded history. Oklahoma does not have very many earthquakes at all, so this one was intriguing. Turns out the epicenter of the quake is in the heart of an area where "fracking" is used to extract oil and natural gas from deep below the surface.

Fracking is controversial as it involves pumping water, sand and chemicals under pressure to force out gas and oil, especially natural gas. Here's an animated film I discovered, produced by Earthjustice.org that explains the process and the environmental and health risks associated with it. The Forum topic is here with additional videos describing problems with fracking available for you to see.
