Worms Eat Plastic Now

According to researchers in Spain and England, the larvae of the greater wax moth can efficiently degrade polyethylene, which accounts for 40 percent of plastics.

The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and degraded about 92 milligrams, or roughly 3 percent, of it. To confirm that the larvae’s chewing alone was not responsible for the polyethylene breakdown, the researchers ground some grubs into a paste and applied it to plastic films. Fourteen hours later the films had lost 13 percent of their mass—presumably broken down by enzymes from the worms’ stomachs.

When inspecting the degraded plastic films, the team also found traces of ethylene glycol, a product of polyethylene breakdown, signaling true biodegradation.

In the 1971 novel Mutant 59: The Plastic Eaters, Gerry Davis and Kit Pedlar wrote about a biological time bomb that could destroy necessary infrastructure.

"On the surface, in the freezing December air, the smell of the rotting plastic began to hang permanently in the air. A cloying, wet, rotting smell similar to the smell of long-dead flesh. It filled streets and homes, basements and factories. Traffic lights failed, causing irresolvable jams.... The breakdown of plastic spread into Broadcasting House.... A gas main with polypropylene seals on its pressure regulators erupted into flame.... Plastic cold-water pipes softened, ballooned, and burst, flooding into shops, homes, and restaurants.

"Slowly and inexorably, the rate of dissolution increased; failures occurred in increasing succession until, within forty-eight hours, the centre of London had become a freezing chaos without light, heat, or communication."

Earlier still, Michael Crichton wrote about it in his 1969 novel The Andromeda Strain.

"the organism...Mutated to a noninfectious form. And perhaps it is still mutating. Now it is no longer directly harmful to man, but it eats rubber gaskets."

"The airplane."

Hall nodded. "National guardsmen could be on the ground, and not be harmed. But the pilot had his aircraft destroyed because the plastic was dissolved before his eyes."

Larry Niven also used the idea of an organism that ate material necessary for a civilization's infrastructure: see this note on superconductor-eating bacteria from Niven's 1980 novel The Ringworld Engineers.

I miss Michael Crichton; here is a list of about sixty science fiction in the news stories about Michael Crichton's works.
