It's also very unlikely that nature won't adapt to plastics. They have great amounts of chemical energy, and they're everywhere. Already you can see great decreases in plastic lifetimes, and they're decreasing faster and faster. The lifetime advantage plastics provide won't last. e.g. https://en.wikipedia.org/wiki/Ideonella_sakaiensis https://en.wikipedia.org/wiki/Ideonella_sakaiensis Without microbes breaking it down (which can be achieved in a number of ways, and generally it is at least slowed down) wood can last a millenium.
