I wonder if anyone has actually data-mapped all the known (even)
volcanoes and underwater geo-thermal vents and calculated how much
'pollution' they produce?
Then there are all the lightning induced forest fires ...
That said, I don't think we mammals 'enjoy / benefit' living in all
this pollution so any *real* improvements along those lines should be
a 'good thing' (so not electric cars or PV panels etc).
