I say they are full of it.
Difference here is, I actually tested it.
Their test used "fine black carbon" not smoke. Big difference between "fine black carbon" and smoke that has drifted for miles.
Also I noticed there wasn't a control so this doesn't appear to be scientific at all. So for all we know the "fine black carbon" could also be settling out all on its own.
And now I proved they are full of it.
Remember the same government said all the koof vaccines were safe and to run out get the jab don't worry about side effects, if you had a bad reaction or maybe allergic to it, that's because you're a racist anti science bigot.
