Extracting tar from these sands amounts to cleaning them. So, this is not polluting : it is cleaning !
…please change my mind because I am obviously completely wrong here 😋 ( I should also read the article )
P.S. : Article say it creates bad air pollution … honestly, I was expecting severe water contamination lasting for decades …
P.S.3 : Such a rabbit hole ! Reading the science paper what I understand is they sample air while flying a plane through the area downwind. Then, they heat this air sample to burn all those hydrocarbons and finally what they analyze is the carbon dioxide combustion product which is one PPM above the normal air concentration or 400 PPM so they measure 401 PPM and on top of this maybe they did this while in Canada there was those huge forest fire that change the air to orange smoke for many months … Well, I don’t know if this is good science or not but I have doubts.
