Fortunately, microplastics seem to be more like dihydrogen monoxide. Great many studies show how DHMO is toxic and dangerous at both cellular and macro levels. This is a problem, because DHMO is even more ubiquitous in the environment than microplastics. There's kilograms of it in you and me right now!
Yeah, microplastics, an industrial byproduct, are totally like dihydrogen monoxide, something essential for life, which we and all other species, evolved for billions of years to need for basic functioning.
I mean, this kind of thoughtless rooting for any tech and tech byproductto the level of this comparison, similar to the chavinistic "my country, right or wrong" , is like those who were consuming radioactive stuff in the early 20th century to prove "it's completely safe".
and "any tech is always good" is about as much scientific as flat-earth.
