Songfacts®:

• This rocker was written by Nuclear Assault frontman John Connelly and bass player Dan Lilker. The song is a warning about impeding environmental disaster if we don't start taking care of the Earth. This was a prescient statement in 1989, as decades later scientists made a clarion call for action, explaining that global warming was devastating the planet.
  
  The "critical mass" Connelly sings about is the point of no return where there is nothing we can do about the Earth's destruction. Scientists would later explain that there could indeed reach a point where damage to the Earth is irreversible.
• In our interview with Dan Lilker, he explained: "It was just a real strong, heavy song. You have to balance your thrash songs with your heavy, straight-ahead, mid-paced songs."
