We recently watched the film Gasland. It is about fracking. Hydraulic fracturing or fracking is a means of natural gas extraction. It's scary stuff and not just because of the effects it has on the environment and people's health. It's also scary because I fathom to understand how any sensible 'authorities' would even allow such a nightmare process to happen. But it does and it is a growing industry, now creeping it's way into the British countryside. Be afraid, be very afraid and in the meantime, be informed.
