Depends on what is in the smog and if it precipitates out in the rain, if it rains before it blows away. The moose in Maine had the same problems over 30 years ago from industrial polution from the midwest that blew northeast and rained out as acid rain. Sounds like a hysterical rant from a treehugger. Too soon to tell what will happen. Probably nothing. Look at the Global Warming crisis. Nothing but lies usually for some hidden agenda.
