Sense Sonnet - Chiller

On Ice

Ice is good for the polar bear,
A platform from which it can hunt.
Sea ice was and now is not there.
Greenhouse gases get the blame brunt.
Maybe humans could change their ways
Of burning fossil fuels a lot,
And make Earth go to cooler days.
Maybe humans can, maybe not.
The ice ages have come and gone,
So ice most likely will return,
For humans then to fret upon,
As more fossil fuels, humans burn.

When all Earth gets covered in ice,
Won't polar bears think that is nice!
