Unfortunately your kind of argument is what often comes up in ecological debates. I am not denying the impact of microplastics but raising the point that it is a complicated equation. Banning plastics is just a silly comment. What about tires, medical devices, plastic jugs to get water to people with no access to clean water. It is an easy argument to make if you might be in a place of privilege and you can hand wave most of those problems away. My posistion is that yes microplastics pose a possible issue on a go forward basis, I don't know the totality and I believe that humans are still better off than we were before plastics.

Banning micro-plastic sources from consumer purposes isn't so silly if it contributes to dementia and other neurological issues long term.

They're finding they stuff embedded in utero lining; your argument strikes me as the same old rebuttal to the things we can't political agree to study. You can't deny there is a lot of business momentum to keep plastics in production, no? And yet the more we learn the more checkmarks in the minus column for petro-chemicals accumulate.

Not sure why you are bringing politics up. This has nothing to do with it.

We most definitely need to fully study the impacts of plastics on the human body. We don’t know the full extent of what it’s doing and it’s important we figure it out.

It’s a complicated equation that we do not fully understand. It’s easy to say just ban it but there is are a lot of other negative consequences that will come out of that decision. That’s my point, none of us know the exact outcome either way so it’s silly and all too easy to just make proclamations like yours and then sprinkle in some dementia with it. I am certain you can pull out a study that has a link between the two but I suspect we still don’t know the true origins of dementia and we do not know the full impacts of plastics on human health.

I bet you don’t even know the source of microplastics fully. I sure don’t. For all I know it is from car tires that makes it into the water ways and we eventually drink it or consume meat that has drunk it.

We don’t know the equation enough to know what concerns we should weight heavier on a global/population scale.

> Not sure why you are bringing politics up. This has nothing to do with it.

Politics is the struggle to gain, retain, and use power. The use of plastics creates a huge amount of wealth and power for many, by definition anything that could affect this is political.

Sorry but that drags this conversation in such a wild direction. You have gone so off track that it no longer makes sense.

But we should keep producing more year on year until it's studied properly?

Studied by whom? Petrochemical companies have studies on their stuff back for decades. They'd never endanger the public to improve their bottom line. Plastics are fine, dontchaknow?

I think this has taken too much of an emotional turn instead of logical. You will not be able to get plastics banned until there is conclusive evidence that a significant portion of the population is dead from it. Ignoring corporations, I do not believe you can get any large enough portion of population to ban it or even limit it in any meaningful amount.

I personally am excited for the coming years and hopefully us having a better idea how we can use plastic more efficiently. In the near term we should be able to get a better idea of major contributors to microplastics and maybe be able to reduce those.

I'm not talking about just banning plastics (it should be banned involving anything food related IMO) but actually taxing these materials as the hazardous materials they surely are.

Why would you ever expect a bottling plant to move away from plastic when there is no incentive? Why would anyone move to better materials or continue researching when there are cheaper alternatives that aren't rightfully taxed against their externalities?

Why are we as a society, one which has banned lead from gasoline (resulting in lower crime rates across the world) or banning CFCs to repair the ozone layer, feel so helpless trying to hold these corporations accountable for not polluting our world around us today?

Is it really that impossible?

I don't think I generally agree with a plastic tax but lets imagine there was one. I am honestly not even sure how you would set the price, my whole point is the externalities are hard to measure. I also suspect the cost of the implementation will be on the shoulders of the consumer. We can hand wave it away and say we can create more rules to prevent it but at the end of the day that is most likely what will happen.

There's no reason the tax needs to directly reflect the environmental impact. We figure out an amount that is enough to change corporate behavior without bankrupting them, maybe with some kind of sliding scale to put more responsibility on larger businesses who would otherwise benefit from regulatory capture, throw in some exceptions for the aforementioned medical devices, etc. "Pricing the externalities in" is a nice political justification but in reality this kind of thing happens because we've already decided that plastics are significantly worse than the alternative and we want to incentivize change.

Regarding consumers shouldering the cost - well, yeah, regulation drives prices up; even my liberal self agrees that that's broadly true. Those same consumers will be shouldering the cost of an environment permeated by toxic microplastics, which we are increasingly being driven to believe will be a greater impact than that of more expensive consumer goods.

and when they jack up prices, we use the tax revenue to subsidize the poor so only the well off pay that assholery, we can do this for carbon in all forms.

For someone so skeptical, why buy the 'cost increases will be passed on to the consumer' BS? Clearly that's not true.

First, price increases depend on elasticity. I'm guessing that ketchup demand is pretty elastic; it's not diabetes medication or higher education.

Also, we can assume Heinz, being sophisticated, has already priced it for the highest possible marginal return; there's not necessarily room for increasing the price without reducing return (by driving down sales).

Yeah that will never happen in many countries.

It's possible but there is no voting solution to achieve it

Biologically it is. You could argue on long term effects of microplastics but it's clearly less of a risk than food poisoning.

People die from food poisoning. No one has died from microplastics, so far as we can tell.

you don't actually know that. if, imagine, the increase in dementia or cancer or any major illness is increased at all by microplastics, and we will find this out before long, and it will indict Big Plastic and Big Oil, we will learn it's killed far more of us that you whoring for Big Oil and Big Plastic suggests.

These subthreads from my comments are absolutely bonkers, people are willing to give companies that routinely lie to us again and again sometimes lying for literal generations to us!

and people STILL give them the benefit of the doubt.

People willing to allow others to poison us so they can earn money.

Do bottles shed microplastics?

Manufacturer > store > pantry > garbage can > dump.

Isn’t the majority of this buried in the ground in dumps that are sealed off from groundwater?

I suspect our clothes, cars/tires, houses, and other things that live outside contribute more to microplastics than food containers.

Yes, they shed plastics:

The question should be reversed, is there anything made of plastic that doesn't shed particles? It seems likely not, they all tend to shed.

Do air molecules in gaseous form colliding with the plastic contribute to micro-plastic production? Oxygen is a notoriously active element....

I don’t know the exact sources and that’s what we should be studying. For all we know it’s tires to roadways to rain runoff that makes it into ground water or bodies of water that we eventually treat for drinking.

Fair point. Needs more study before dummies like me make assumptions.

(Still not buying any Tupperware, though).

Me too! I use glass at home.

That’s a fair point reusable containers are a great candidate for replacement with glass. You are right overall though we definitely seem to be polluting our environment with plastics that will never go away.

Use the same rule for tupperware that you apply to shirts! I store and buy food in plastic containers often, but I always move it onto a ceramic dish before I microwave it.

Ditto here but only recently. Currently working all the plastic I can put of my food prep workflow. Insidious situation we find ourselves in.

Most microplastics in your environment are from tires and textiles. Blow molded PE is way down the list on what I'm worried about.

> Should plastic containers shedding millions of nano particles be considered sanitary?

It's not really on the scale of sanitariness. It's a pollutant and a problem. You can even say it's not worth the tradeoff. But no, plastics are not unsanitary because they can produce microsplastics.

I've read the main contributor to microplastics is car tires. Do you have an idea if these types of consumer containers are a significant source?

Agree the incentives are screwed up, and that could help.
