Maybe the only thing more worrisome than microplastics everywhere is unstoppable plastics eating organisms everywhere, eating through all plastics everywhere.

Usually these bioengineered yeasts need pretty specific growth conditions in order to eat in this case ethylene glycol, not raw finished plastic. In this case they say "plastic-derived substrates" which means they're pre-processing the waste plastic.

Good thing microorganisms are famous for their slow rate of change in dynamic environments…

I'm not sure what this adds. The yeast here is chomping ethylene glycol for carbon, and tons of soil bacteria can already do that. And I should add that highly specialized industrial/lab yeasts have existed for a long time and aren't prevalent in the environment, they just don't like to grow outside of narrow(ish) conditions. Highly prevalent wild yeasts tend to eat a variety of sugars, not glycol.

Of course, the lysine contingency.

Perhaps soon you'll be needing to apply stains or sealants to your outdoor plastic items. Maybe even purchase treated plastic products that we worry leach toxic chemicals into their surroundings.

Timescale is the important bit. If organisms degrade plastics in a few hundred years then what plastics are uniquely valuable for will be quite fine indeed.

Why is that worrisome? Might give the fish a chance whose bellies are filling up with plastic rubbish

for all the reasons in the book/movie/television show 'The Andromeda Strain'.

There’s a fantastically silly but fun book about this the name of which eludes me.

Not plastic, but 'Cats Cradle' by Kurt Vonnegut has something kind of like that.

there was a time in history before fungus came along and ate trees so there were just a huge amount of trees around that couldn't decay. (which is why we have coal actually) this could be something akin to that.
