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.
Maybe?
Evolution takes a long time and unless we are dealing with microbes and fungi, generations are counted in years or decades.
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.
I’d argue we’re like roaches. Most of us may die, but we’ll survive.
…only a few million years
David Cronenberg’s Crimes of the Future takes a look at the idea
…or go extinct.
