A place for optimism, relentless positivity, anti-doomerism, and snuggle sessions.

We're all in this together, and a better world is possible!

This is now also a space for organizing tips for our collective survival as we confront climate change and everything else. Still no doom-posting. We're here to work together, support each other, and boldly face the future.

Rules:

  1. Familiarize yourself with the site-wide Code of Conduct

  2. No doom, no gloom, only bloom. There's plenty of room for doomerism elsewhere. This community is solely for having a positive outlook on the future and spreading good vibes.

  3. Be kind to your fellow users. This also means no arguing in the comm. Arguments and negativity are not conducive to blooming. Constructive discussion is good. No interest-policing. Support your comrades in their joy!

  4. Always share good news. We can't exactly enforce this one, but if you have good news, please share it with us! Keeping happiness and positivity to yourself is the twelfth type of liberalism.

It turns out the world may not be quite so contaminated, it's just the research laboratories.

Scientists may have been unknowingly inflating microplastics pollution estimates, and the surprising source could be their own lab gloves. A University of Michigan study found that common nitrile and latex gloves release tiny particles called stearates, which closely resemble microplastics and can contaminate samples during testing. In some cases, this led to wildly exaggerated results, forcing researchers to track down the unexpected culprit.

I love science. I don't mean that disingenuously . I do kinda love that years of research on this topic asking the big important questions, and it all gets tripped up by someone eventually asking the small, easily forgettable, procedural question.

Homo Plasticus on Arte and DW is a great doc, and the team in Italy addresses the challenges of lab equipment beung mostly plastic. The numbers they find in food are still shocking.

I believe there are studies where the gloves and other equipment were overlooked, but pushing this narrative and discrediting them all seems a bit too convenient for one particular interest group.

"We may be overestimating microplastics, but there should be none," said McNeil, senior author of the study and U-M professor of chemistry, macromolecular science and engineering, and the Program in the Environment. "There's still a lot out there, and that's the problem."

ya i'm pretty sure it's still a big problem

Please be true! Please be true! Please be true!

I'll be honest, I've always been a bit suss of the whole "microplastics" thing.

It feels like something that'll end up in a future "Adam Ruins Everything" episode where he reveals it was never a big issue and really just distracts from other more serious pollutants. Plus, "plastic" has always been a bit of a New Age boogeyman, and while I agree we make a lot of shit out of plastic we shouldn't, I don't think we should demonize polymer materials. They actually have a lot of benefits when it comes to medical and sanitation technology. Yeah plastic waste is bad but lets not throw the baby out with the bathwater.

It has its uses. Though, food packaging has really gotten out of hand.

Oh definitely.

But I think a lot of people don't realize how much plastic is used by the medical industry, and for good reason! Turns out if you're really dedicated to sanitation and antisepsis you gotta throw a lot of stuff away all the time.

But that's a much more justifiable use than buying a hamburger in a bag from 7/11.
