No offence but using variety of elements in a molecules composition to determine its 'exoticness' is a horrible metric.
Human life is probably one of the most complex machines out there, and that's all we are; shit carbon alone I'd say is the most exotic element due to its versatility, look at CNT's, diamonds, and oil
(big fancy ones like uranium tend to be less interesting cause their lack of stability, carbon has 4 really stable bonds it can do a shitload with - aka hold a plastic bottle together for a couple thousand years)
It'd be weird if something didn't evolve to eat it is my point. It's just dead animals.
Sorta, evolution takes time and plastic is pretty biologically inert - hence why its hard to do anything with, its in like an energy deadzone
Forgive my ignorance, but isn't that what UV does?
No worries! It does but only at the weakest points, and these break points would be more easily broken down by any means (chemical/biological or thermal through radiation).
The issue is that the entire molecule isnt made up of these, and so anything UV would be able to do (at least in our atmosphere), biologically bactieria can't do much better.
Its also part of the reason we can't just toss our trash in a big ol UV light or just leave it out in the sun and expect it to disappear; all its useful properties will but the brittle plastic leftover won't. This is why recycling plastic is so hard compared to other materials.
Thanks
