Or incorporate it. Basically what George Carlin said. Evolution will witness a new paradigm of life plus plastic and will keep evolving as if nothing matters.
It took 60m years for fungi to evolve to break down lignin (trees) and the eventual oxidation of the lignin decay products has caused the most rapid climate shift we have ever seen
I think chances are higher we all die, the microplastics get embedded in a layer of rock worldwide, and nature moves on without us. Evolution is way too slow to keep up with manmade horrors.
Is 60 million years not too long?
On the grand scale of time it isn’t
I wholly expect that some time from now humans will gather to talk about the moral implications of letting creatures that depend on microplastics go extinct due to our efforts to remove plastics from the environment or if we should be producing plastics to keep them alive.
Bold of you to assume we’ll still be around at that point.
