Divisible* 

Our species has malfunctioned and we’ve finally met our match.
It’s waited all these years for the right time for it to hatch.
First there was the ice age where we had to deal with frost,
but it seems like global warming is the place where we’ll be lost.
We’ve flaunted our dominion and must be reprimanded
It seems as though our prototype’s about to be disbanded.
It’s ironic that a virus so small that it’s invisible
might be the thing that proves that mankind might be divisible.

Divisible: capable of being divided by another number without a remainder.

Prompt words today are malfunction, flaunt, prototype, frost and match.
