Is it a critical issue?
I'm not read up on the effects of microplastics. I keep hearing they've been found in more things, but what does that mean?
Is it dangerous? Are there actual diseases or medical side effects like we saw from lead for example?
From limited understanding, it causes inflammation as your body reacts to any amount of stimulis.
And since we cant digest them, our bodies try to fight it, causing inflammation
You may as well consider it the lead of the 21st century.
Children in 3045 will be mockingly deriding us in history class for how flippant we were about plastics.
Really? There doesn't seem to be much evidence of any sort, and I don't have a horse in the race. Other than my body.
Theres plenty of evidence that it causes inflammation, and your body cant break it down. So if it wiggles itself into a spot in your body that isnt easily flushed, its going to stay there causing inflammation basically forever.
On top of that, "microplastic" is a catchall term. Rubber dust from car wheels is a microplastic, that you breathe in any time youre within hearing distance of a road. All that rubber in your lungs, alone, cannot be good.
Thats not even thinking about all the other forms of plastic, or their degredation chemicals, or the films and chem linings they carry.
Sure, particulate matter of any sort isn't a good thing to inhale. I'm just wondering if there's anything specific to plastic. Some of the additives are proven to be awful but e.g. polyethylene has so little available surface energy I wonder if it can be doing much, chemically speaking. If it's not this it'll be something else, I'm sure.
From this article...
Okay, yes, that's my current understanding.
Bold of you to assume there will be a 3045 for the human race.
Oh, easy, we are functional cockroaches of survival.
Maybe we will be a different species by that point, but our descendants are still in many ways us.
Decent point but I also wouldn't put it past us to completely extinct ourselves one day.
the diversity of microplastics is enormous
most of it is from the plastic that they wrao bread in because they feed it to animals as is
Or from tires, as they shred and grind themselves into a fine plastic compound so light it floats in the breeze off roadways.
Yes it's not good, but research is lacking.

Given my druthers, I would rather not find out the hard way.
