TIL in the Carboniferous Period, no fungus existed to decompose trees. They just grew on top of each other up and up.
The weight of the trees was so great that the ones on the bottom got squished and became coal. That’s where coal is from. Bonus fact: the whole time this was happening, sharks were hunting in the oceans. Sharks are older than trees and fungus!
At some point this will happen with plastics too. Soo much plastic is ending up in nature, with soo much energy ready for the taking. When one fungus or bacteria mutates just right to munch on that feast of plastic, that vast energy source will ensure that organism multiplies rapidly.
And that is when plastic stops beeing useful for many of the tasks we humans use it for. If your plastic container decomposes as rapidly as a cardboard box, it will quickly become much less usefull.
There are already organisms which can digest certain plastics. The problem (AFAIK) is they can digest other stuff more easily. So maybe in landfills ill work, not so much in nature were there's other organic matter for the taking.
Well the carboniferous period lasted 60 million years. If life takes even a fraction of that to figure out plastics, humans will be long, long dead by the time they do. But I'm sure it'll be something interesting for future non-human civilizations to ponder over.
Speak for yourself there, buddy. I plan on being around for at least another 82 million years. I'm uploading my brain into a terrible android as we speak.
Unfortunately due to capitalism I can't tell you or it'll cut into my money and thus ability to live for millions of years. Once I've made my money I'll DM you so that you're second in line.
