Sorry people, but you can't stop it: 1. https://www.euronews.com/green/2022/04/11/how-much-plastic-d... 2. https://www.theguardian.com/environment/2022/mar/24/micropla... 3. https://www.theguardian.com/environment/2019/apr/15/winds-ca... Because humanity and capitalism's incentives are just wrong. Bottling companies like Coca Cola and Snapple have long switched to plastic bottles, and externalized the cost to the env…

I've read that the majority of microplastics come from tire wear (national geographic quoted 28% of the total), and because there's no good alternative to wheel tires, it's unlikely we'll see a decrease of pollution here. So even if we found an alternative to bottles, plastic bags, clothing, etc, it still won't make a dent in pollution unless we convince the world to use a form of public transit that doesn't make use…

I also learned in a Not Just Bikes video that the US tire lobby prevents regulation on quieter car tires. I bet there are ways to make tires that shed fewer microplastics - it's just that we don't do it.

Changing the container your soda comes in is like sanding off splinters from the sharpened stake you're about to stab into your leg.

It's a lot more complicated than that. And I will note that I drink a lot of tea and fruit juice, which also come in plastic bottles. Most drinks come in plastic or metal containers these days. Most of the time, I buy mine in plastic containers. I wish it were different and I've lived without a car for more than a decade in the US. Try advocating for a less car dependent infrastructure in the US. It gets you mostly p…

But do people buy those drinks daily? I drink mostly just tap water - because it is convenient - as it is almost everywhere.

I live in a 100 year old building with lots of plumbing issues. I don't trust my tap water. I limit my consumption of it.

So, yes, I buy such drinks -- and consume them -- daily.

This is possibly a class issue. Lots of people in the world lack reliable access to clean water. There are entire charities devoted to trying to remedy that fact.

Tap water contains about 1.67–2.08 ug/ml of nanoplastics on the larger side ( https://www.sciencedirect.com/science/article/abs/pii/S00139... ) So this article was working with concentrations 10x larger on mice (usually worse ability to filter). Beyond that, they admitted that microplastics did not induce an effect which is most of the plastics found in the ocean, etc...

"1.67–2.08 ug/ml" is incorrect. Your link states "1.67–2.08 ug/L". In other words, the paper is about the effects of nanoplastic concentrations which are 10,000x greater than in tap water.

Yeah ok, I'm going to keep drinking tap-water and stop reading clickbait "science" articles.

They do these kinds of studies on mice because mice have a high homology with humans, and a huge number of the findings extrapolate to humans.

Yes, and as a model organism they're fantastic. But I feel any and all studies on mice need to have "on mice" always in any published study or news report about that study. But it's one thing to pump a 100g/100g of micro plastics to bodyweight directly into the brain of a mouse and another to study mice in a mostly natural environment filled with plastic dust in similar proportions to what we find in our human lives.…

Reminds me of those "mobile phone radiation is bad for you" studies. I read a few and calculated the energy they exposed those mice with in joules per kg, and it was like putting your head in a microwave oven for a few seconds. No wonder the mice had some issues afterwards...

Make it easier for her by taking on the chores of washing them and preparing them. If you're insisting she do something differently, ask her if there is anything you could do to make it easier for her to do it -- since this is clearly a more important change for you than for her (at this time).

I did offer to do that but the main problem is she doesn't want to carry the items and it can be heavy for her with all the tools she carries (she's a piano technician). Really only solution would be finding lightweight alternatives, but haven't had luck with that.

Metal? Lighter and less prone to breaking than glass. Also less inert maybe, but probably better than plastic.

What is with putting superfluous place names in front of things? Are you trying to sound fancy? You have steel and wood food containers.

American cheese is different from other kinds of cheese. Canadian bacon is different from other types of bacon. English muffins are different from other types of muffins. OP isn't trying to be "fancy", they're trying to communicate. This is a weird thing to get agitated about.

What we have here ... is a failure to communicate.

(I'll see myself out)

My mum when I was a kid in the 90s: we don't store things in plastic, glass or ceramic only Me when I was a kid in the 90s: mum is a f'ing idiot wtf is wrong with plastic this hippy shit is dumb My mum 2020s: so plastic huh? Me 2020s: ugh.

I think the bigger problem can be that it is present in drinking water. Both bottled and tap water. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9103198/

Of course it cannot be positive to store food in plastic containers either. But difficult to avoid.

Lacquer is resin from trees, not plastic. I don't know if it's better for you than plastic or really anything about its chemical composition, but it's not plastic. Edit: After reading more, there is an acrylic lacquer that was developed in the 1950s that contains plastics, but outside of that, normal or traditional lacquers are typically biological in origin. https://en.wikipedia.org/wiki/Lacquer

When you say "normal", does that mean "common"? As in, if I buy lacquered wood, can I expect it to be synthetic or biological? Is there a way to tell, or do you just have to trust the source?

By Normal, I mean "Non-Synthetic" as it regards to lacquers.

For the lacquer you buy in the stores, you will have to examine the contents to see if you have actual lacquer or synthetic petroleum lacquers.

As far as wood products, if it was made after the early-mid 80's, assume that if it was lacquered it was done so with a synthetic, or if it is some form of manufactured wood.
