Bugs across globe are evolving to eat plastic, study finds
The increasing amount of plastic being added to our environments has created intense selection pressure for microbes that can break down plastic for energy.
Looking at environmental DNA samples, researchers have found 30,000 different enzymes capable of digesting different types of plastic. Almost 60% did not fit into any known enzyme types.
While previous plastic-eating microbes had primarily been found in garbage dumps or recycling plants (locations with very high levels of plastic), the enzymes in this study were collected from soil and ocean water throughout the world, meaning this phenomenon is even more widespread than we thought.
The goal is to utilize these enzymes for more efficient recycling–essentially breaking plastic down into its basic building blocks to reduce or even eliminate the need for new virgin plastic. An enzyme created in 2020 is already being used to recycle plastic bottles in only a couple of hours.

oh bugs as in BACTERIA not like. millipedes.
