I can't find it in the article, but I assume this is the same as all the other plastic eating organisms; They can eat plastic under specific circumstances, but would rather not. What is in the article; they can only survive on polystyrene if it is mixed with other food and nutrients.

Not true.

We found that mealworms on the polystyrene-bran diet survived at higher rates than those fed on polystyrene alone.

While the polystyrene-only diet did support the mealworms' survival, they didn't have enough nutrition to make them efficient in breaking down polystyrene.

Many of the ones fed only polystyrene for a month did survive, they just fared poorly as with any organism that’s eating only one substance for an entire month. But they did live, which is pretty impressive.

They have gut bacteria that can break down polystyrene for nutrition. They just can’t eat only polystyrene and nothing else and thrive. It’s mostly an area of research because they want to use the bacteria in processing waste, not that the mealworms are going to be the answer as-is.

We're going to develop or find some efficient life form to break down plastics quickly. Solve our waste problem. And it's going to get loose into the wild and start breaking down plastics everywhere, uncontrollably. Straight out of Larry Niven's Ringworld series (theirs was a superconductor-eating bug).

Probably not though, that's just science fiction that never happens in reality. The nylon-eating bacteria that naturally evolved found long ago in waste areas never broke out to destroy all nylon. So at least there's an example of it not happening.

That's fine, really. Eco problem solved and we need alternatives to plastic (made of oil) in the next few tens of years anyway.
