PFAS: Last Week Tonight with John Oliver (HBO)

bremnet says...

Howdy - I don't know if "addressed" is the right word. Commented on, but not given sufficient perspective. Having said that, the problem is incredibly complex, so there should be no expectation that Mr. Oliver's video or any other single thesis on the topic could possibly suffice.

Your "one chemical bond difference" is an appropriate consideration, but with recognition that once we reach on the order of C20-C40 length dispersable or emulsifiable molecules as surfactants / surface energy modifiers, the insoluble polymers come into play, with not 30'ish bonds growing one at a time, but leaping to 20,000 or more. No doubt the pool has already been irreversibly pissed into by the irresponsible producers that convert small molecules into very, very large ones, but with some control, responsibility, and integrity in our industrial process owners (yes, hell just froze over) there is no reason why we could not safely continue to produce the polymeric forms of PFAS. We do so for substantially more toxic chemical conversion processes today.

It's interesting to note the (usual) examples brought forward by others in this post (Teflon cookware), just waiting for someone to mention Gore-Tex, but by far the biggest impact won't be on consumer goods that we all touch regularly and recognize the name brands of, but will be on the industrial / commercial uses of these polymeric families that are pervasive in the systems / processes that we all derive benefit from every day. Ironies exist, that perhaps confuse the "all PFAS are bad" premise ... consider - effectively every seal, gasket and control valve in a water purification plant is most commonly made of a PFAS polymeric compound, PTFE included, all tested to rigorous specifications and compliance by specific agencies that do nothing other than deal with potable water (thankfully not the EPA - it's National Sanitation Foundation (the other NSF), or Water Research Advisory Scheme (WRAS) in the UK etc.) .

So my contention and the view of many in the end user community is that it's not the final form of some of these compounds that are bad, it's the horrendous messes we leave producing them. We can't unwind our Clock of Dumb, but killing the entire crop just to get rid of the long ago seeded weeds doesn't solve the actual problem, it makes it much, much larger.

Thanks for your comments.

To be fair, most of your complaints were addressed in the piece.

For instance, medical implants, fairly stable, yes, but not in extreme heat like cremation, so as used they’re toxic to the environment despite being considered stable and inert.

The reason to ban them all was also explained, banning one toxic substance at a time means one chemical bond difference and the company can go ahead with Cancer causer 2.0 for a decade until it’s banned for being toxic, and then repeat. It’s how they’ve operated for decades.

I’m fine with outlawing the entire class and putting the onus on the chemical companies to prove any new variants are safe instead of forcing the hamstrung epa to prove they’re unsafe. I also think any company that dumped it into waterways should be instantly and completely forfeited to pay for cleanup. No company has the funds to pay for cleanup, but their assets are at least a start.

What Are You Doing With Your Life? The Tail End

StukaFox says...

I don't often say this, but fuck this video.

If you're 25, the end of your life is an abstraction and the whole "there's time to change things!" is a nice balm. When you're 55, your death isn't an abstraction, it's a fact of life that dominates more and more of what remaining time you have left. The awareness of impending mortality is insidious once you're passed 50. It creeps into every part of your life and every decision you make.

Let me teach you one of those amazing words the Germans come up with for describing various forms of existential agony: weltschmerz. Loosely, this is a form of sadness when one realizes what is versus what could have been. This is the compound interest of regrets and choices not made, or made poorly. Not only does weltschmerz grow with each year, its very presence amplifies itself because the more you know what could have been, the more you see what the cost of that absence is. Then, if that's not evil enough, that knowledge focuses the mind on the time remaining and how little you can do to negate the harm done, which then re-amplifies the weltschmerz.

You can slap whatever Hallmark bullshit you need on this to get through the day, but weltscmerz never goes away. It's always there. It's there at 3:00am when you wake up in a silent house and look at everything around you as consolation prizes for races not won. It's there when you see your friends succeeding in a million different ways that you didn't. It's there when you look at 6 million lines of text you wrote and realize you're not going to be Hemingway after all.

So fuck this video. I don't need a cutesy animated memento mori, I've already got a wall clock in my death row cell.

Here endth the rant.

(Nick Drake nailed weltschmerz perfectly in "When The Day Is Done". Here's the video to that song:

World First 360 Double Backflip Tailwhip on BMX

luxintenebris jokingly says...

stuff like this makes me think about what his obit will look like. because if he leaves it up to someone else, his double spin, counter-clock-wise, twisty, world's first thingy might end up as "liked to do tricks on a bike".

Brave Men Save Pelican Tangled In Fishing Line

StukaFox says...

I love 84!

I had some friends into exotic cars and we'd take 84 over to the coast now and again, mostly because we had a shit-ton of money and a shit-ton of spare time to kill -- the Dot-Com fucking rocked!

There's a bend in the road just outside La Honda on the coastal side that's a 15mph hairpin with a tree at the apex. It's a lovely goddamn thing, especially when you forget it's there. So here we all come, lane-trading and exercising general assholery in cars that cost what a nice single-family home does.

Oh FUCK, the turn!!

My friend in the 911 does this beautiful trail-brake and swings through the curve. Elise follows suit, complete with smoking tires. Next up is Countach. He BARELY holds it together, but gets through without any real drama.

Now it's my turn.

Did I mention I was driving a '97 Camaro Z-28? Yeah, Camaros of that year are good at exactly one thing: driving very fast in very straight lines. Corners? Yeah, not so much. I realize I'm in trouble and I'm coming into the turn WAY too fast. I grab the shifter and get ready. My plan is that I'm going to slam it into first, let the rev limiter do its thing to save the engine, pull the e-brake and swing the tail, then punch it and swing the ass-end around and launch out of the curve with smoking Z-rated tires and all!

And HERE WE GO -- grab the shifter, yank it all the way down and...

That's when California emissions standards fucked me.

You see, when you buy a Camaro Z-28 in California, you don't actually get first gear. You get what's called a California First, which is actually SECOND gear, because if you were actually able to use FIRST gear, the goddamn car would belch enough emissions to make a farting Brontosaurus blush. And second gear ain't exactly gonna work for my little plan.

tl;dr is that I hit the no-lock brakes hard enough to get my speed down and was able to bring the ass around with the little e-brake trick. I wasn't out of the woods because I over-corrected on the way out and spun. The same God that I spite and don't believe in actually saved my ass and I didn't end up going off the road. Apparently, he loves fools and Z-28 Camaros.

I honestly had more fun in that car than the law allows: sometimes literally, like when I got clocked at 110 coming onto the straight at King City. Good times, man, good times.

newtboy said:

I love that stretch of coast.
As a teen I used to party at hidden beach a few miles North. The only access was a sketchy 6" wide path on the cliffside, so we knew cops wouldn't bother us there.
Should've taken 84 home, less time driving in the stink and you could've gotten great BBQ in La Honda. ;-)

Trumpfeld

newtboy says...

Just to be clear, Trump thinks you are so dumb you could never count backwards by 7s, or identify the day, month, year, city, and state you're in, or what a clock face looks like at 2:45.

He believes knowing things like this makes him a genius, ahead of everyone in intelligence, and he just can't imagine any questions that might be harder or that anyone else on the planet is intelligent enough to score a 30/30 on a dementia test.

He also brags that not one person who knows him expected him to pass it. *facepalm

Re-contextualizing Tucker Carlson

Police fire (paintball?) at residents on their front porch

newtboy says...

Shoot back with black tallons. Where are all Trump's "ready to go" 2A people? Certainly they would stand against this tyrannical thuggery....unless they're really all babies cowering behind and threatening with their guns but only when only they have guns to threaten with. No. Couldn't be.

Fucking violent thugs shooting people peacefully sitting on their porch.
They have zero authority to make you be INSIDE, only on your property.
This is not policing.

Shoot those thugs in the head like Trump said to. Presidential order through Twitter, shoot the THUGS. Burn their hideouts too...police stations. They aren't policing, so they don't deserve them.

I won't piss on a cop if they're on fire, or use my breaks if they're in front of my moving vehicle. By far, they're the most violent gang in America.

@bobknight33, does giving someone a nice ride on the clock excuse this? Or illegally arresting the press? Or repeatedly unannounced, shooting people dead in their homes, or repeatedly suffocating people in public using banned control methods, and how about lying about all of it until civilian video goes public?
Edit: You patriots aren't doing a thing to stop this tyrannical clampdown, gangs of THUGS shooting peaceful citizens on their porch backed by tanks, I guess all that "our guns protect us from a tyrannical government takeover" is definitely bullshit, we're sending those thugs to your house next to collect your guns, you don't need them anymore since you're all snowflakes.

Cop Drives Man Over 100 Miles After Traffic Stop ...

BSR says...

I don't think you can put a price on being a good example of public servant these days. I get the feeling he would have done it off the clock with his personal car, but I digress.

newtboy said:

Since it was pre-approved, my only remaining minor gripe is being labeled a super Samaritan for something he was paid to do.

Cop Drives Man Over 100 Miles After Traffic Stop ...

newtboy says...

It took a while, but it seems he was on the clock according to the highway patrol spokesperson, but got permission so wasn't derilict. No idea if he got golden time or regular pay, or for how long, but he got paid, so personal kudos rescinded, kudos to the department head that OKed it.
A gofundme to pay the department back might be good, but I'm not starting one....I wouldn't know how.

BSR said:

You could find out if a Go Fund Me has been set up to reimburse the money cost. If not you could start one to make your point. Who would be the hero then?

Cop Drives Man Over 100 Miles After Traffic Stop ...

newtboy says...

Are you saying we did pay him 4-8 hours of overtime then?
If you dropped your job to do something nice on the clock, you would get fired, doncha think?

If we went off the clock, kudos.

Sure, more good than bad, but 100 good deeds don't erase one horrific crime. Ask Pablo Escobar, the Robin Hood of Medellín. He's not a good guy because he helped the poor, right?

bobknight33 said:

You just love to shit on cops.

I know this is a un believable story to you because in you small little peanut mind all a cop can be is bad.

There is more good than bad but you narrow minded head is blinded by your own prejudice .

Anderson Cooper Struggles With Las Vegas Mayor's Logic

newtboy says...

1) Do you see protesters practicing social distancing? Hint, they aren't, because the virus is a liberal hoax to bring down Trump. So moronic, but fine as long as they're only infecting each other. Open businesses and they'll restart the outbreaks and restart the clock on quarantine, wasting all the gains of the last 6 weeks.

2) open or not you'll have no tourists. Tourism is on hold for the moment, and large gatherings too. Casinos would have to rebuild themselves first, they are designed to make social distancing impossible. If no tourists guarantees failure, they Damn well better prepare for failure, because there are no tourists.

3) if they go to work and force a second, longer, more strict quarantine, all that happens anyway plus a few tens of thousands more dead.

4) agreed, and the black and white choice made solely on the basis of improving the economy must ignore the obvious health risks that themselves threaten the economy further. Opening early sets us back months, back to the start of stay at home orders, back to before the economic crash and massive losses, but without first restoring the market or economy. Do you think the economy can handle another crash? Because that's what you'll get if Trump and Trumpsters open before the minimal guidelines have been met....two weeks of declining infections and deaths. Those are Trump's guidelines, probably insufficient, but better than the "we'll be the control group in a pandemic experiment....and better than Trump himself who abandoned his own recommendations days after releasing them and now supports protesters. *facepalm

bobknight33 said:

If you open, even with limited capacity, social distancing you may stay afloat.

If you don't open you will have ZERO tourist. That guarantees failure of business, city, county and the state.



If the employees stay home they will run out of $, go broke, loose the house and car and the job that let them keep it.

Seeing thing as a black and white choice is not allays a good thing. And this is not one of them.

Finally a Doctor on the News Talking Fucking Sense

greatgooglymoogly says...

If everyone somehow isolates and we get down to only only 10 new cases a day, and we let everyone out, that only resets the clock to February with the addition of a million or so people already infected and immune. Everything goes back to shit in another couple months. People's behavior changing will help slow the spread, but will not prevent it. There's plenty you can do outside the home a safe distance from other people with minimal risk, certainly less than just going to shop for food. It's ridiculous they are shutting down beaches where it's simple to walk 20' away from anybody else. To limit crowds just close down parking spaces.

Antibody tests should allow recovered people back into regular life, but the only way we get a lot of recovered people is to have a lot of sick people first. Keep the elderly and high risk people confined, and let everyone else out with reasonable precautions(no gatherings over 20, etc). The only other alternative is a 6-12 month lockdown and 100% testing, which is simply never going to happen. You would still have to lock down the borders until the rest of the world has it under control too.

newtboy said:

Because some states aren't quarantining and interstate travel isn't restricted, you need to stay home 3 weeks AFTER the entire country finally quarantines, otherwise it's all for nothing and the outbreak will restart with a vengeance and that 100000-250000 dead will become 6000000+-.

Why The Right Wing End Game Is Armageddon

shinyblurry says...

The bible was written almost exclusively by Jews, both the Old and New Testament. Jesus was a Jew and so were most of His apostles. The events of the majority of the books in the bible happened in Israel. Christianity is a Jewish religion. So, it shouldn't really surprise anyone that the bible has a lot to say about the Jews. Where they came from, how they got there, and what happens to them in the future.

Christian support for the Jews is a relatively new phenomenon. During the reign of the Catholic church, Jews were persecuted by Catholics and forced to convert to Christianity. The Jewishness of Jesus was lost to history; this is why you see much of the art during the middle ages depicting the Lord as a European man.

What changed is that the Jews returned to the land of Israel in 1948, something that many scholars of time past assumed was impossible. The general teaching was that God had broken His covenant with the Jewish people because they rejected Christ and that the church was now the new Israel. This is called replacement theology.

Yet, the Jews did return to their own land, a unique event in all of history. Never before had a people group been displaced from their own country, scattered all over the world for thousands of years, and then regathered to their original land with their cultural and genetic purity intact. This is a true miracle which anyone can plainly see is evidence of the hand of God working in the Earth on behalf of His chosen people.

The video makes it seem like the idea of Israel being integral to end times prophecy is some kind of leap, yet anyone who has studied the bible seriously knows that nearly everything predicted about the end times revolves around Israel, and particularly Jerusalem. There are numerous prophecies in the Old Testament stating plainly that God will scatter His people and gather them back to Israel in the last days.

The scripture predicts that the Jews will build a third temple. At this moment the Dome of the Rock, the golden domed building you see in photographs of Jerusalem, stands in the place where the third temple must be built. You could sum up the entire tension in the middle east in two words: "Temple Mount".

Not only are the Jews ready to rebuild their temple in a moments notice, they have created all of the implements of the temple and have been training priests to serve in the temple. The scripture declares that for end times prophecy to be fulfilled there must be a third temple. I can confidently predict that this will happen sometime in the future and the Dome of the Rock most likely be destroyed.

I also wanted to mention one other thing. The name "Palestine" was given to the area by the Romans. The Palestinians are not a people group, they are Arabs who settled in the area after the Jews were dispersed around the world. The video really does you a disservice by neglecting to mention the fact that it was the Arab nations that attacked Israel unprovoked on multiple occasions and the Jews against all odds defeated them. It was their right to take that territory and they are under no obligation to return it.

In the end, there will be much more conflict in the middle east, all revolving around the Jews and Jerusalem in some way. You may doubt the scripture but you will see this unfold with your very eyes. One day a charismatic man will come on the scene who will negotiate a peace in the middle east between the Jews and the nations of the world. He will seem at first to be someone who can solve all of our problems but eventually he will establish a one world order and rule the world with an iron fist. He will go into the Jewish temple and declare himself to be God. This is who the bible calls the Antichrist.

So, if you want to know where we are at in the end times, watch Israel and Jerusalem. Jerusalem is Gods prophetic time clock. When you see the Dome of the Rock being replaced by the temple, know the Lord is near, even at the doors.
