So this is a cool thing to notice as you go about your life: there are no unexploited corners in a balanced ecosystem (reference: Sylvia Earle); take note of what in your locale consumes what. If there is energy to consume, something has evolved to consume that. Ants are amazing at making use of small caloric particles that other organisms will ignore because the bits are too small.

Plastic is an interesting case. Plastic is made of long chains of lipids (an energy storage molecule), polymerized into somewhat durable longer molecules. When some critter learns to crack those molecules, things could get very interesting for humans if we’re still around.

I get the meme but a more accurate joke would be:

Ant exists

Ant reproduces uncontrollably

God invents ant eater

Ant be like: what did I do to deserve this.

And now let there be ant lions

If you want to accurate to Biblical tradition. Good created both the ant and anteater but Adam was the one who named him. (Using English of course, he was a god fearing American)
