Scotland has a decision to make: to frack, or not to frack. The controversial technique could be used to release gas and oil from the shale rock which lies beneath central Scotland. Large energy companies are keen to do this, and say it is important for both our economic growth, and energy supply needs. But fracking has a bad reputation. Its opponents believe it is dangerous, with the potential to cause pollution and even earthquakes. The Scottish Government has announced a temporary ban, but for some that is just not enough. David Miller reports from the front line in the war over fracking, where the two sides are locked in a fierce battle for the hearts and minds of the nation. He sets out to find out whether shale gas extraction can be safe, and whether Scots can be convinced to give it the go ahead.
