Sense Sonnet - Acher

Sudan

The northern white rhinoceros
Has lost the last known male, Sudan.
Upon him was put the onus
Of last chance reproduction plan.
But he was 45 years old,
And his health had begun to fail.
The desperate hope the world did hold
Was fragile in this rhino male.
Sudan was euthanized because
His quality of life had gone.
In memoriam some did pause,
All the harder to carry on.

On a ceremonial plaque -
A carrot, Sudan's fav'rite snack.
