‘“Fracking”, or rather hydraulic fracturing is a subject that fosters great passion and concern in many. The word “frak” was recently used as an expletive in a remake of a 1970’s television classic, to replace another well known Anglo-Saxon curse, and in Swedish fräck means “audacious”, “shameless” or “bold”.’
