Cover art for Natural Science lyrics by Rush

The essence of the song is in the refrain, "Wheels within wheels . . ." continuing withTime after time; We lose sight of the way; Our causes can't see their effects." So science natural science at that is critical to advance but not without checks and balances. And if the causes don't see their effects (think global warming) science will undo itself. So science like natural must be tamed to survive annihilation. Whose? Ours? Earth? Both. The most endangered species is the honest man - the one who has the bold audacity to say "WAIT! We must stop this."

All should strive to be part of that species. Only then will we survive annihilation.
