Can you break that down so I can understand better. It sounds bad.
The PH levels in your blood are going to decrease, reducing storage for necessary elements of metabolic reactions (calcium, phosphorus) in the medium. This is going to impact children and the elderly first, where cellular death is going to slowly cascade across their bodies.
There is no evidence blood pH levels are affected. This is alarmist media. Are we going to ban soda?
There absolutely is, and you can do a simple experiment at home with some water, indicator solution (one can be made with red cabbage juice, but we used to use methylene blue when we did it at the science centre) and a soda water maker (or dry ice) to see it happen.
It's not completely representative, obviously, but blood is mostly water and the same pH change we can see in carbonation water will happen to blood plasma.
so we should ban carbonated beverages or not?

Biochemist here. People on Lemmy should read links they post.
As with any buffer system, the pH is balanced by the presence of both a weak acid (for example, H2CO3) and its conjugate base (for example, HCO−3) so that any excess acid or base introduced to the system is neutralized.
A lot of academic labs love to get attention with alarmist claims, and assume the actual data was done properly.
See DTT, see BPA, bullshit that never dies.
Too much carbon dioxide vs oxygen in the air. Your body cannot power itself and unless you find a supplemental source of oxygen, you asphyxiate in the destroyed atmosphere.
Like trying to breathe on Mars.
