Although plastic particles in the air are increasingly coming into focus, knowledge about their distribution and effects is still limited. Chemical analyses from Leipzig now provide details from Germany for the first time: Around 4% of the particulate matter consists of plastic. Around two-thirds of this comes from tire abrasion.
Then you gotta ask yourself how you’d compare microplastics vs other types of pollution.
Tricky question, gets back to the whole, “I’m a part time internet shit poster and not a pollution expert” bit. I think that the impacts of microplastic pollution is serious and needs to be reduced where possible and regulated when it can’t be reduced. I also think that the concern about MPs is valid and serious, but a bit overblown. I’ll leave you with the last bit to think about as well: There will never be another person born on this planet without microplastics in their body.
There’s always a trade-off of harm humans are causing themselves and the planet. My hope is that one day we are plastic and we will be enriching ourselves instead.
