The End-Permian Die-Off

Instantaneously,
On geological scales,
It happened suddenly,
With no warning at all,

A colossal calamity,
Of fire and fury,
Killed 90%,
Of all biodiversity;

Worse even,
Than the K-T event––
β€˜Good’ for mammalians,
But killed T-Rex;

The next event,
Could be about to happen…
β€” The worst, ever,
Mass-extinction.
