  • Yes agreed, all of the PFAS just keeps adding up and we know it’s causing all sorts of issue. I hope we can get that legislation in the near future where manufacturers are required to clearly indicate what products have PFAS in their end-product or in the process of making it. Because PFAS is in so many things and most people don’t even realize it. They might know about the non-stick pans, but it is in many more products, some surprised me to learn it was in it. If it’s clearly labeled, hopefully people will chose the product without the PFAS instead of the one with.


  • YSK the finished PFAS in the end product like non stick pans is perfectly safe. The long molecules with strong carbon-fluoride bonds don’t interact with biology at all. You can cut it up into tiny pieces and eat it, it will just come out the other end. Even if you were to implant it inside your body, it would do nothing. Actually materials like PTFE are often used for medical implants, specially because they are so inert and safe.

    So why is PFAS bad? Because in the production of the long molecules, short molecules are required. Those molecules are a waste product after use and are usually dumped. In the past they were dumped in huge amounts. However these short molecules are very dangerous, they do interact with biology and cause all sorts of issues including cancer. The people at Dupont figured this out very quickly, but chose not to report on it. It took a long time for the issue to become public. With their waste material giving the company a bad name, they said they invented a new short molecule to use, which was much safer. Except it wasn’t safer at all, they knew it wasn’t and they again didn’t make that info public. After they were found out a second time, the governments classified all such chemicals under the PFAS family and regulated all of them.

    Unfortunately our world runs on stuff like PTFE, so it’s still widely used, without any substitutes available. And we keep on dumping those dangerous short molecules into our environment. And because they don’t decay over time (hence the nickname forever chemicals) they are here to stay. We’ve also found out even a little bit of it can be dangerous and we’ve dumped a lot of it into our water supply. So that’s why PFAS is bad.

    TLDR: If you own anything with PTFE or similar materials like non stick pans and cutting boards, don’t worry they are totally safe. Since the damage is already done, keep using them as much as possible, so the damage wasn’t for nothing. If you are going to buy new stuff: avoid any products with PFAS as a waste product. Governments are working on regulation to make this clearly visible when purchasing a product. The less we buy, the less we produce, the less we pollute.


  • This is super dumb, it’s the same logic all those movie studios used to have the government crack down on piracy (destroying our rights in the process). Just because someone uses an alternative, does not mean that company has lost anything. It doesn’t mean it was a sale and that sale was removed by the alternative. If the alternative wasn’t available, the sale might have been there, but it might also have not, there is no way of knowing (and my instinct is most of the time there would not have been a sale).

    For example with movies, just because someone pirates the movie, doesn’t mean they would have gone to see the movie in theaters. They could have for example not bothered watching the movie (most likely), since they deemed it not worthy. They might have waited to watch it till it aired on TV or for cheap on a streaming service. Or might have watched it with friends on a streaming service for example.

    And with software, just because someone uses GIMP doesn’t mean they would have bought Adobe tools instead. For example they might have simply not done the thing, if it costs money they wouldn’t have bothered. Or they might have used one of the dozens (if not hundreds) of alternative tools. They might have paid someone else to do it, who might already have the Adobe tool, so not an extra sale for Adobe there. Or they might have used butterflies to change air currents, which focus down cosmic rays to directly flip bits on their computer to edit the image (C-x M-c M-butterfly if you are using Emacs).
