MODERATORS
Then maybe we need to examine "modern day life" with a more critical eye. Some sacrifices may need to be made, because they are worth being made.
There are also measures that lie between "ban" and "use freely". If we cannot eliminate the use of these chemicals in chipmaking, then we need to reconsider the disposability of these chips, or we can even consider if less effective processes result in less damaging chemical use, and accept a bit of regression as a trade-off.
One of the main uses for PFAS is electric vehicle batteries. So if "modern day life" means reducing CO2 emissions, then it will inevitably mean increased use of PFAS.
Four words: Investing in public transportation.
Public transportation depends on buses, and buses require either fossil fuels or batteries.
Orders of magnitude less than mass private vehicle usage.
Of course. But if we want to reduce CO2 emissions then buses will still need electrification - and therefore require PFAS.
Furthermore, public transportation will not be able replace all private vehicles. Or at least, it cannot replace them all quickly enough to avoid catastrophic climate change. By the time the necessary infrastructure was built, it would be too late. Therefore, electrification of private vehicles will be necessary, which will also require PFAS.
Basically, we are at a late enough stage of CO2 emission that the only realistic hope of avoiding catastrophic climate change requires mass production and adoption of EVs.
Very all-or-nothing response.
Okay. But again. My comment was that if elimination isn't possible, reduction should be pursued.
So saying "we still require this" is completely irrelevant.
Nowhere has anyone even hinted that replacing all private vehicles is the goal.
Once again. Reduction is the goal.
So saying "we can't replace all" is completely irrelevant.
Buses require almost exactly the same infrastructure as private cars.
No. What the hell. Why would that be true?
Public transport is a better option for basically every major population centre. And for those centres, we should not be encouraging private vehicle ownership, but rather replacing that as much as possible with public transport. Hell, even if that public transport is on-demand low-occupancy shuttles and ride sharing, that's still better.
Electric private vehicles are better than internal combustion, but they are still awful.
I think it's relevant to the person you were replying to as well as the original point of the article.
PFAS are critical to some modern technologies. In some cases, they cannot be replaced. Any time we replace cars with buses, we will need PFAS to electrify the buses. And likely we will need more PFAS in the future than we are using today.
I was the top comment. So no.
Which is why I was talking about reduction in cases where elimination isn't feasible.
Bloody hell man.
You're right, you were quoting the article not another person.
Regardless, you asked for a critical look at the necessity of PFAS and whether it is possible to reduce usage. My original answer is the same, namely:
One of the main uses for PFAS is electric vehicle batteries. So if "modern day life" means reducing CO2 emissions, then it will inevitably mean increased use of PFAS.
Who would have a problem with us returning to an average lifespan of 40 years?
Yeah, me I do, which is why I want to get rid of these forever chemicals because that's how we're going to end up with 40 year lifespans again.
We aren't getting rid of our nutritious diets and vaccines which are the two biggest factors in history that have extended average lifespans. Not Teflon pans and firefighting materials.
I think you overestimate the toxicity of PTFEs. You know they are used in implants?
You underestimate the toxicity of PFAS chemicals and their manufacture. I work in a toxicology lab, I know a lot of people researching PFAS right now.
To make PTFE, they used to use a chemical called PFOA, which causes multiple types of cancer and other pathologies. Everyone has been exposed to it, especially since they have been found to just dump it in whatever river is convenient. They had to stop using it after getting sued, but now they just use a different chemical that had been show to have the same effects. And again, they're just dumping it into rivers knowing the fines for polluting won't be as bad as actually containing the chemical properly.
That is one PFAS chemical. There are so many others. Do not let corporations poison you for profit and then lick their boots for the privilege.
Seems like the problem is the lack of proper environmental protection and enforcement.
Love the closing personal attacks. Really drives your point home.
Your mamas so fat , oops I mean PHAT.
My comment was about how if elimination of these materials is impossible, then we should figure out how best to reduce their usage in an acceptable manner.
Jumping straight to black-and-white "So you'd send us back to the dark ages?!?!?!" type of response is kinda wild.
not the people insisting on the chemicals, clearly.
