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.
I’m confident that it will happen, these things just take time. There’s enough energy floating around bound up in plastic polymers, and the chemistry is simple enough, that something will learn to make use of it. 100 years is just way too short in evolutionary time for it to happen on a large scale.
Maybe we should be happy it doesn’t happen, breaking down all plastics which are currently everywhere would probably result in massive CO2 emissions. That’s why I’m always sceptical when these kind of articles appear; it gives some people an excuse to say the overuse of plastics isn’t an issue.
