Eating one wild fish same as month of drinking tainted water: study
by Daniel Lawler

Locally caught fish in rivers and lakes could be a major source of exposure to "forever chemicals" PFAS, new research has warned.
Eating one freshwater fish caught in a river or lake in the United States is the equivalent of drinking a month's worth of water contaminated with toxic "forever chemicals", new research said on Tuesday.

The invisible chemicals called PFAS were first developed in the 1940s to resist water and heat, and are now used in items such as non-stick pans, textiles, fire suppression foams and food packaging.

But the indestructibility of PFAS, per- and polyfluoroalkyl substances, means the pollutants have built up over time in the air, soil, lakes, rivers, food, drinking water and even our bodies.

There have been growing calls for stricter regulation for PFAS, which have been linked to a range of serious health issues including liver damage, high cholesterol, reduced immune responses and several kinds of cancer.

To find out PFAS contamination in locally caught fish, a team of researchers analyzed more than 500 samples from rivers and lakes across the United States between 2013 and 2015.

The median level of PFAS in the fish was 9,500 nanogrammes per kilogram, according to a new study published in the journal Environmental Research.

Nearly three quarters of the detected "forever chemicals" was PFOS, one of the most common and hazardous of the thousands of PFAS.

Eating just one freshwater fish equalled drinking water with PFOS at 48 parts per trillion for a month, the researchers calculated.

Last year the US Environmental Protection Agency lowered the level of PFOS in drinking water it considers safe to 0.02 parts per trillion.

The total PFAS level in the freshwater fish was 278 times higher than what has been found in commercially sold fish, the study said.
Non-stick pans are among the products that use PFAS, which have been linked to a range of serious health issues.

'Greatest chemical threat'
David Andrews, a senior scientist at the non-profit Environmental Working Group which led research, told AFP he grew up catching and eating fish.

"I can no longer look at a fish without thinking about PFAS contamination," said Andrews, one of the study's authors.

The findings were "particularly concerning due to the impact on disadvantaged communities that consume fish as a source protein or for social or cultural reasons," he added.

"This research makes me incredibly angry because companies that made and used PFAS contaminated the globe and have not been held responsible."

Patrick Byrne, an environmental pollution researcher at the UK's Liverpool John Moores University not involved in the research, said PFAS are "probably the greatest chemical threat the human race is facing in the 21st century".

"This study is important because it provides the first evidence for widespread transfer of PFAS directly from fish to humans," he told AFP.

Andrews called for much more stringent regulation to bring an end to all non-essential uses of PFAS.

The study comes after Denmark, Germany, the Netherlands, Norway and Sweden submitted a proposal to ban PFAS to the EU's European Chemicals Agency on Friday.

The proposal, "one of the broadest in the EU's history," comes after the five countries found that PFAS were not adequately controlled, and bloc-wide regulation was needed, the agency said in a statement.

All the more reason to eat beef.
 
Yeah, I saw this. Unfortunately, his way out of The Predicament is also "technology will save us".

Right, but he believes that the reason the drop off on your graph is occurring is because schools are focusing on all the woke crap rather than educating on the sciences.

The fall of the innovation empire and its possible rise through open science

Abstract
There is growing concern that the innovation system's ability to create wealth and attain social benefit is declining in effectiveness. This article explores the reasons for this decline and suggests a structure, the open science partnership, as one mechanism through which to slow down or reverse this decline. The article examines the empirical literature of the last century to document the decline. This literature suggests that the cost of research and innovation is increasing exponentially, that researcher productivity is declining, and, third, that these two phenomena have led to an overall flat or declining level of innovation productivity. The article then turns to three explanations for the decline – the growing complexity of science, a mismatch of incentives, and a balkanization of knowledge. Finally, the article explores the role that open science partnerships – public-private partnerships based on open access publications, open data and materials, and the avoidance of restrictive forms of intellectual property – can play in increasing the efficiency of the innovation system.

Keywords: Innovation, Research productivity, Open science, Intellectual property, Patents, Research incentives, Public-private partnerships, Networks

And correlates inversely to this.

Now, obviously the solution isn't to cut out education, but maybe we should be pushing our students more towards STEM than towards Liberal Arts, Equity Studies and Philosophy?
 
Science and technology will save us...

I'm sure gutting education budgets in lieu of corporate tax cuts because of "scary CRT" and "too many low income households" in an encroaching attempt to privatize education all the while slashing public research budgets because libertarians tell us "Elon et. al. can do it better and cheaper" as we approach 1T$/yr in defense while education and healthcare debt balloon to comical levels has nothing to do with it.

Imo, STEM without the guidance of the liberal arts and humanities is just a machine running for... itself, monstrous.

Humans survive because through technology we mitigate the effects of weather change
110 million live below sea level ,expected by year 2100 to rise to 190 million....I think we can fugue out how to keep 80 million more people alive below sea level
We cant wait for the Earth to fix itself
------------
The upshot of the study is that 110 million people worldwide live below the high-tide level; that includes many partly protected by sea walls or other infrastructure, as in New Orleans. Even under a scenario of very modest climate change, that number will rise to 150 million in 2050 and 190 million by 2100

You're not wrong. But clearly the cost of perpetuating this civilization, its maintenance much less its growth, is rising. So far we've been able to throw cheap fossil fuels at every problem and win a measure of success, but with a concomitant measure of pollution (I use that term broadly). This approach is unsustainable.
