"Toxic atmosphere" definitely implies something that I don't seem to be finding in the actual paper. We regularly sit in environments that are 2-3x the levels of atmospheric CO2.

Not saying the paper isn’t AI, but “for example” is an extremely commonly used phrase that you should not be using as an AI indicator

This is such a bad paper. They take the NHANES data, average it for all participants, don’t bother controlling for things that have far more direct relevance to individual bicarbonate levels (e.g. diabetes, antacid use), and just assert that an observed correlation is causative.

Complications of diabetes can lower serum bicarbonate, not increase it.

In general, it is true that there are many causes of a rise in bicarbonate, but doesn't this only makes the situation more precarious?

Should not be a surprise since we have know about CO2 Levels and fossil fuels for many decades. The surprise is nothing was real was done. Compare what our generation did with this knowledge against the sacrifices the WW2 generation did. In WW2 many items were rationed in the US for the war effort, including gas . We knew something had to be done to be done in the 70s, but did we sacrifice our lifestyle for the good…

I assume you mean boomers? Might time to stop blaming them, since at this point some of them are great-great-grandparents and the following generations do not seem to have shown any more appetite for changing course.

Earlier quoted context omitted.

It's not a good idea because while one can avoid eating red meat, collagen hydrolysate is mainly obtainable only from bovine sources. Fishes are polluted. As one gets older, collagen becomes necessary for remaining healthy, and no synthetic amino acid mixture comes close in effect. Also imagine that meat can in theory be lab grown.

No thanks. I'd rather not get prion disease. Also:

1. Eating collagen supplements has not been established as a necessary dietary requirement. Your cells synthesize collagen from amino acids, with vitamin C serving as a required cofactor. Some trials report modest improvements in wrinkles, skin hydration, joint pain, or bone measures, but that supports collagen as an optional targeted supplement, not something everyone must consume to remain healthy.

2. Bovine is common, but commercial collagen also comes from porcine skin, chicken cartilage, fish skin/scales, and jellyfish. A randomized clinical trial, for example, used pork-skin collagen, while another tested fish-derived collagen. Actual collagen is animal-derived unless produced through recombinant biotechnology.

3. “No synthetic amino-acid mixture comes close in effect.” This lacks evidence. In a 2025 randomized double-blind study, participants received 30 g of collagen hydrolysate, a free-amino-acid mixture precisely matching collagen’s amino-acid profile, or placebo. Collagen and the amino-acid mixture produced similar blood amino-acid increases, and neither increased muscle connective-tissue protein synthesis versus placebo over six hours.

Look at your CMP (Comprehensive Metabolic Panel) blood test results. It has a test named Carbon Dioxide. This test may have a reference range of 20-32 mmol/L. Subtract your value from the max value -- that's your leftover buffer as the atmospheric CO2 rises, although serious intermittent problems are risked at a level of 31 itself. There is a more specific blood gas test that only a hospital can perform. Fwiw, my val…

Mine was 26 mmol/L yesterday, but the reference level is given as 22-29 by my lab, not 20-32.

As a software engineer, what can we do to help with anthropogenic emissions? I want to know how I can use my critical thinking to protect the future for us.
