In an interview with Kerrang!
published February 20, 1988, lead vocalist Biff Byford
said of this track it "is about the pits," later he added it's "about ecology, using up all the coal and fishing the seas dry" - a protest song.
The pits is a reference to coal mines. Saxon hail from Barnsley in South Yorkshire, which was a coal mining town until the closure of Barnsley Main Colliery in 1991. Coal is anything but an ecologically friendly source of power.
