Here's a thought. Since there are enzymes that break down plastics, isn't it just a matter of time before we get macroscopic organisms that start to make it and use it to feed on the plastics? The reason we have coal is because plants developed lignins and for a long time fungi could not break down the lignins (hence the accumulation of carbon). Then fungi developed strategies to break down lignins and the accumulation of carbon stopped. Same with this. It's just a matter of time till some organism develops a way to break down plastics into usable material.
