Poor Sport Poem by Ima Ryma

In Canada, in Churchill town,
The Polar bears come in the fall
To wait for sea ice to firm down
On Hudson's Bay by nature's call.
But climate change has made it so.
There is less ice upon the shore.
The bears must stay, nowhere to go,
Having humans round more and more,
Being provoked or being hungry
Is why a polar bear might harm
Humans by instinct, and rare be,
Rarer than humans with firearm.

Humans who shoot the bears for sport -
Which species is the sickest sort?
