When earth's span is done
Nothing will be lost
But a diminutive planet circling a sun
Lost like a grain of sand within a vast desert.

One planet among trillions
Home of pretentious children of Adam
Who thought themselves unique
And finding too late they were not Gods
But ruinous for all they dominated.

Colin Ian Jeffery
