Even places like Dubai and qatar there will be air pollution and not only becouse of oil the heavy raining but now the war Will couse Also not balanced climate.
There is large establishment of emirates in London UK so the wealthy ones can go there while war is in middle East.
Btw....the air will become bad there it's not healthy you pay some huge money for Dubai Luxury but you can't breethe clean air ..only way will be stay indoors with filtered air.
The bombs smoke might be causing some pollution but in long term it would be pivotal in reducing pollution as it reduces the number of people. People are the ultimate cause of pollution, the less the better.
